I saw that Flipper Zero on your desk, you bold boy. but I imagine its a tool that would help with slime network mapping, with everything on wi-fi or some wireless signal?
Another reason the shipments were delayed was due to the FCC getting in the way. They claimed the chips were to be used in phones, not in VR Trackers, and denied the shipments. This led to them having to ship everything back to their main facility, get all the paperwork done, get approved by the FCC, change the labels on every single tracker, repackage it all, and then ship them back out. It has been an absolute mess. I have a slew of emails explaining the whole situation. They have been VERY good about keeping me fully up to date.
Just to clear up a few things: 1. The skating can be heavily mitigated by our anti-skating option, which can be dialed up or down depending on personal preference. The better your skeleton is, the less you will need this. 2. The autobone never needs to be done after you get your proportions correct (unless your are growing). The 4 moves only need to be done once in the thirty second window. 3. Joycons are really, really bad. Try not to judge slimevr on its tracking fidelity after using just joycons. Its the bottom of the barrel in terms of IMU performance. 4. 5 slimes are needed, minimum, to track lower body. It wont work with only three (for maths reasons) 5. We have regular events if you want to come ask questions or get your tracking ironed out. If it seems like a big scary thing, just come lean on the community a bit! We love new people
I would like to add that on personal experience joycon tracking is decent with 2 joy cons on each leg + a phone on hips, and I'd say they work perfectly as long as you don't crouch or crawl, any fast rough movement or sitting position that is not a chair will break the tracking, and the wrangler takes a very long time on recognizing the 4th joycon, but it's a nice last resort if you don't have anything else (like me)
I've had problems with firmware updating on diy slimes and the community was fast and responsive at helping me out. It's like the ideal tech support we could only dream of!
I'm not even into VR, I don't have a headset, but now I'm really interested in slimeVR, it looks like a great project, I would love to build them myself and Play around with maybe coding something non-vr using the tech
(1/2) for anyone else who noticed the floatyness in clips like 12:19, that's to do with head/waist lock settings in Vrchat 90% of the time, i had that issue before and fixed it by changing the headlock/waistlock settings, if your slimes have high latency it would be displayed in the server, and would be more likely to present as the entire system going out of sync with itself, like half a leg moving before the other half rarther than the entire system seeming to lag behind together as one, love yall :)
holy shit you've solved like all of my problems ever. i dont use slime but i have crazy floatiness all the time and i didnt even think this would be an issue. i feel like a lot of tracking problems are on vrc's end
I have slimes and this is a pretty good overview! I will say though: once you get your body measurements correctly you never need to do the little hula dance ever again. When your trackers move position you can just do a full reset and mounting reset which are consistent and take about 20 seconds combined. So your extra calibrations after you got it right werent even needed!
I understand it's been a year, but I have a few questions. 1, is Slime really worth it, even after all this time are there any issues. 2, how long was your shipping? That is all, thank you.
Meta is obsessed with inside out. That goes with tracking and the experience itself. They focus on standalone but barely talk about the PC part of VR. They'd rather use headset cameras to track the upper body and make estimates of where the legs are instead of designing some external body trackers.
You don't need to redo autobone or proportions ever again once your body proportions are correct, even if you mount them differently! As long as they are on the same part of your body, you only ever need to do the full and mounting reset at the very start, which takes all of 20 seconds while standing. Then when you notice drift, which takes at least 20-30 minutes with a lot of physical movement, you do the yaw/fast resets which is done in like 3 seconds. And when you do the yaw/fast reset, you do not need to stand up in a t-pose or recalibate your VRChat avatar tracking! You can do it while standing, sitting, or laying down, as long as your torso, arms, and legs, are facing the same direction as your HMD.
The Wii controllers used IMU based tracking, and there is an IR camera in each controller that is used to re-calibrate the controller position using the sensor bar as a fixed reference point. The distance between the lights and the angle of them give the Wii remote the info it needs to find its position. We could probably do something similar with a camera looking towards the slime trackers to re-home them when they come into view to automate the calibration process.
In theory that should work. Most headsets with inside-out tracking basically work like that: their controllers have lights on them in specific patterns that are easy to recognize on a camera (usually IR LEDs which emit light that's invisible to the human eye, but visible to the headset's tracking cameras), and whenever they're within view of one of the headset's cameras, it can automatically recalibrate the position.
@@IkBenBenG With my reverb g2 at least, I think it only has a gyroscope and inside out tracking but no IMUs. Unfortunately, tracking an object with cameras is hard and inaccurate, and would require a ton of development. You would also need at least 2 cameras in different (known) locations both looking at the same object to obtain its position in 3D space.
I’m an XR developer and XR/IT support agent. Seeing you admit, your struggle really resonated with me and make me feel a little bit better about when I get a little “five headed “. I’ve never heard that term before.😂🎉 this looks like a great solution and I’m glad that you’re sharing it with us. Thank you so much.
You don't need to do the autobone/automatic proportions dance each playsession, because people's body proportions don't change. Only the automatic mounting calibration needs to be run each time, which only takes a second (the one where you squat). So no hula dance necessary, once you get your proportions down to your satisfaction :)
I ordered Slime VR (7+3) in March '22 Original Shipping date was the end of August' 23 First delay to end of September '23 Second delay to November' 23 And now with the last post update they got delayed to the end of December '23 I am a very patient person, but if it gets delayed one more time, I'll cancel the order... Yeah, that my experience with Slime VR so far 😢
oh i already canceled it and made my own. got a 3D printer and the parts for literally the same price, but now i can learn a thing about them, got a free printer bascially and am able to fix whatever breaks. DIY slime is the way.
Hey, you still blame developer for unseen problems like FCC and Corona? You didn't even look around how many people are happy with SlimeVR? Then you should have more trust and patience. They even found new problems and make them even more better. You will get improved version at least.
I've been using SlimeVR (via phones) for about 2 years now, and it's been amazing! There are some downsides to it, like how often I have to recalibrate, but overall, I love it! Thanks for the new video, Thrill!
@@FAKEAXISwould you say they're worth buying? If so, how many trackers should I get. I play vrchat, and I don't do nothing crazy, just want to express myself without having to speak.
Yippee the slime revisit! Ordered mine during the initial crowdfunding campaign and I’m so excited for when mine finally ship home. I’ll finally be able to join my full body friends in VRC and stare at a mirror all evening lmao
Awesome video on an incredible technology! Great editing and presentation. SlimeVR has improved dramatically since the last video you did on it, for sure. There's things regarding setup and autobone that still need to be tweaked (autobone can be just wiggling around as long as the heels are planted according to the dev who made it, and animations will be added for simplicity), for sure, but overall it's way better than back then - that flashback sequence made me laugh, as well as the Level 99 Autobone bit (I got assigned that role in the discord server!) This is really giving me a nudge on showing all the tips and tricks I know about SlimeVR, so thanks for that - I really want people to have the best experience they can with these! Much love to both you and PHIA!
@@a_british_lass_stream_archives I just saw this now, but yeah! I'm doing good, I am actually working on my first commissioned avatar based off of Deira! It's very cute, kind of a gothy build.
@@ZRock35VR oh thats brilliant, i still need the funds to comm a avatar from scratch of my sona, unsure if you've seen her or not, it's been months my memory is foggy
i have close to 7k hours in VR but i could never justify buying trackers and everything just for FBT (ive only used oculus headsets), this gets me very excited for the future of FBT im glad you covered the good and the bad.
They need to make all in 1 suits for tracking and vibration and stop this nonsense of strapping together 8 units. They can make different tier suits for preffered price points, medium priced being likely most sought after.
It would be cool to merge slime tracking with an xbox kinect. It can roughly estimate your position in 3d space, so it could be a continuos calibration.
You could probably use the FaceID sensors on an iphone to get better accuracy. It's sad that no other phone brands have implemented a similar sensor. Edit: Actually, I looked it up and apparently the company that made the sensor for Microsoft was bought by Apple, who used it in their FaceID sensors.
That crazy part is, I know someone (you actually showed them at 11:13) that is working on a next generation prototype using IMU's that are newer then the retail SlimeVR trackers that are newer, that is exciting. What is also interesting is the failed units you have. The same said person I mentioned above constantly gets completely faulty units they must discard.
The SlimeVR setup wizard is nautical miles of a colossal improvement for ease of setup, but the calibration is still per-person and too specific, so the product is not great to share the Full body VR Experience with a family member, friends, at a convention, etc SlimeVR deserves to become the king of accesible FBT, but they should keep working on that setup wizard, and turn it as plug-and-play as possible
I just finished building mine a few weeks ago and I love finally being able to MOVE! They work pretty well too! 😊 Glad to see you revisit slimes and talk about them again!
I built my own Slime's over a year ago and I still use them. Im actually getting ready to upgrade the IMU's within the week. But All in I first built mine for less than 50$ and I couldn't be happier
Nice video. I’ve been waiting on my trackers for a couple years but it’ll be worth the wait. The devs have been very open and honest with all the issues they’ve encountered. Thanks Thrill!
Vive made an Instagram story that said something was going to be announced on the 28th. It had a digital outline of something that looked like the inside out tracker. I’m pretty sure that’s when it’s coming out in a couple days. I’m definitely going pinky up into that. So you’ll have to throw those in your comparisons as well!
Calling them inside-out trackers doesn't really help distinguish them from existing Vive trackers as those are also inside-out. Better to say markerless inside-out vs marker-based inside-out, camera-based vs photodiode-based, or camera-based vs lighthouse-based. I am very sceptical of marker-less inside-out trackers for FBT. Each tracker knowing where it is in space isn't enough for FBT - they need to know where they are relative to eachother and the headset. That relies of them all seeing the same parts of the room and sharing "landmarks", or seeing the headset, or the headset seeing them, or each tracker seeing (and somehow being able to recognise) at least one other tracker. The Quest Pro trackers that work in the same way reportedly exhibit some weird behaviours and problems and they have a clear view of the headset most of the time. Something attached to your feet doesn't have that luxury. I'd expect HTC are going to market them more for tracking a single arbitrary object like a camera for the purposes of virtual camerawork.
@@zig131 it's definitely an interesting problem that I can't wait to see how they plan to address. My best guess is that there will be something like a calibration paper or tag which you would point all trackers towards and they reference in relation to that, but it still wouldn't solve the issue of misalignment with the headset itself
@@zig131 Yeah, that's just me misquoting HTC's words "Self-Tracking trackers. I don't really know what you're going on about in the paragraph, not that tech savvy. However here's some words from what looks like one of the people working on it. "1 dongle for 5 trackers. All 6dof uses IMUs. It’s just easier to use. Much more accessible. In an ideal environment, inside out HMD tracking is as good as SteamVR. We built the new self tracking trackers so there’s a solution to tracking outside the FOV of the headset, without needing external sensors or base stations. Remember lighthouse is still limited to 10m*10m." Hope that helps.
I ordered some diy slimes off the marketplace in the slimevr discord and they got delivered in under a month. They use slightly worse imus (BMI160 compared to the BNOs in official slimes so more drift) but the tracking quality is insane. With 11 trackers its so hard for my friends or most people to spot the difference between me and vive users. Love this project thanks for covering it again
As someone not in the slime community, but with Both 10+6 slimes, and 3 vive trackers, I can say this is a fairly accurate comparrison. Personally, I still use my Vives more often, because there's less trackers, though i will say the slimes are more comfortable (they're so much lighter and thinner!). I've added just one slime as a chest tracker to my daily use setup, and that works great. It wouldn't take many more to add arm tracking, but trying to get everything set up absolutely can be a hasstle. I also want to note that I didn't have any issues with any of the 16 of my slime trackers, at least, that i've found so far. As Thrill noted though, the biggest issue was setup time. When i got my Vives for the first time, I was already in VR, and it took maybe 15 minutes to get them up and running, including a mute friend of mine walking me through the in-game settings for my first time in full body. When i got my slimes, it took me maybe an hour to pair everything and get the setup done. I then spent another two hours messing with calibration trying to get it to a nice place so it doesn't feel messy (and sometimes it wanted to be sideways, which was very weird, but i fixed it in the end). Now that both are set-up, It really does come down to a preference of lighter weight and no occlusion vs time to put them on, and i am a lazy fucker at times. Overall, I can and do thoroughly recomend them to basically anyone. They're definately worth it.
The slime trackers shipped again today! They were held up in customs then reviewed by the FCC and had to be recertified and reshipped but in theory they should be out to backers soon. They also contracted with a manufacturer to get faster and more consistent boards built. Fingers crossed this makes everything from shipping to QA more reliable.
The trackers arrived just over a week ago. I got the set with 5 trackers and 3 extensions. Chest extension to waist tracker, thighs, then ankle trackers with extensions on feet. The good: Simple to recalibrate just stand feet close together facing forward and double tap the chest piece, surprisingly accurate tracking and people can't tell it's not vive or tundra, doesn't need lighthouses so they're portable, straps are comfortable, AMAZING BATTERY LIFE VS COMPETITION. The annoying: Initial setup takes longer, if smaller straps for extensions shift I need to recalibrate, needs more trackers for the same amount of accuracy, if a tracker gets turned off by mistake I have to take them off lay them all flat and reset them. Recommendation: Go with the full set and don't use the extensions. Still cheaper than a pair of lighthouses with the other trackers and you have greater movement range around the house due to not needing the base stations but if you already have the base stations go with Vive or Tundra.
@@UczuciaTM Calibrating is a pain in the ass. Just a fair warning lol. I was doing the movements for hours trying to get it accurate as possible. I eventually just UA-camd a much simpler way
I was an early buyer of SlimeVR, over 2 years waiting for mine so I DIY built 2 sets in the meantime. They're pretty great but the better IMUs in the official Slimes are something I'm looking forward to
I'm genuinely considering it. The prices seem fair for the quality and the quality looks pretty worth it by itself. Glad to see Slime coming back again
If you're ok with some waiting time (all actual orders are planned to be fulfilled by end of April so not so long to wait anymore), it's definitely worth it, especially if you don't have base stations!
@@naomie2680 Thanks for the confirmation! I've been stuck on VR Chat for a while now, so I think I might invest in it for the craic, it helps that I don't need to buy base stations alongside them-
I've got my parts on the way, and with the amount of electrical parts I have laying around, 6 trackers only costs me about $110 USD. If you've got any experience with electronics and parts lying around, Slime might be even cheaper and easier for you than anything else.
Ooo! Exciting, I'm definitely gonna solder up a handful of these and give them a spin, I even have like 90% of the components in stock, I'll just have to order the unpopulated PCBs.
So tempted to sell my VIVE trackers and base stations and just build Slimes. VIVE trackers are just so hard to set up in a way where they will give you even decent tracking.
Hey man! This might be a super dumb question, but I'm new to this side of VR so bear with. Is full body tracking just a way to track my body in something like VRChat for aesthetics? Or could I use my actual legs to walk around in some games? Because going for a run in Skyrim or moving around in Blade & Sorcery using my legs would be awesome! Cheers :)
Not sure what are the odds but I built my own 7+3 and they just worked first time🤪. I had spares too. Followed instructions and never really soldered b4. Followed UA-cam guides to solder correctly. After the last update its worked great! Highly recommend DIY.
I feel like the final solution is just a camera with a trained AI that takes video feed and turns that into full body tacking data, there's been a few studies already.
That really shouldn't be the final solution, at least in my opinion I currently use a Kinect sensor for full body tracking, and while it works well for facing the sensor directly, turning doesn't work very well, even with the algorithms it has for dealing with that Trackers that are able to track themselves are for sure the way to go, since they don't have to get calibrated or anything, they just get turned on
@@davidlewis2171 Generative AI is a powerful thing, kinect doesn't have that, it's old tech. AI can do so many things, look at anything from the 2 minute papers channel like the ones that generate procedural animations, or other that track movements perfectly in 3d with just a video.
@Raulikien That is a fair point, and I agree that the algorithms for determining poses are getting better all the time. However, the other half of it is that while you can have a camera doing that for you, unless the camera is on the headset itself, you're very limited in where you can use FBT. This isn't the case with standalone trackers, where you could use them in any room. With a camera, you have to stand a certain distance away for it to be able to track your whole body.
Thank you for addressing the shipping problem If I had known that it was going to take so long I would seriously re contemplated other options. I order mine march 19 2023 and I’m personally estimating that they may arrive around jul of 2024 hopefully
As a VR dancer and content creator coming from 10 months of using camera tracking to BMI160 14 points! To now BNO085 IMU's all DiY. I have landed on 12 points as the golden point, the neck completes the chest (chest+neck = 1 vive chest, waist+Hip = 1 vive hip). I only do porportions once (got tutorial on it), since u dont grow ;) Also highly recommend straps with rubber on the inside (Trilancer 12'
Slime being twice the work for half the price for similar really good result sounds like just my kind of thing, specially when I can build them myself, it'll be x4 the work for ¼ the price of a full body set, i'm in
I made a friend in VrC and he told me that he bought Slime a while back and can't wait for them to arrive. It's been a year+ since he told me and they still haven't arrived yet. I would love to get me some slimes as well, but if I have to wait a year+ until they arrive then that's just not for me sadly
(7:20) FINALLY I KNOW HOW TO DO THIS PART, I was touching my feet with only one hand and was wondering why it thought I was like 9 feet tall. THANK YOU SO MUCH!!!
To me, the most important thing is I think IMU based tracking will be the future of VR. Not as it currently is, but Pico is working on IMU tracking, Valve is working on IMU tracking, even meta if I remember correctly is working on body position estimation with no or almost no tracking. Laser solution definitely works best, but they're a goal, it won't move further from there. At some point I do believe IMU's will reach that point. By the way, magnetometers (included in the IMUs) can be used to completely negate the drift, but you need a magnetic free environnement which can be hard to achieve sometimes
Where should I look to try and set this up with some joycons? I have like 4 laying around and 1 of them has a broken joystick, so I might as well put it to use.
I’ve been with the HaritoraX for a few years now, and it’s worked decent to pair with the Quest and not need to worry about basestations. I’d love to move to something with far few cables and wires though, it’s easy to get everything all tangled up haha
The power of open source! I want more people to see this so they can understand what it trully means for communities and customers to get a mature open source hardware and software and invest more money in such projects :3
second backer on the slime project: for my set that I bought, 2 of them died within 4 months due to a: with HEAVY drunken use along with horrid temp changes in my room, and b: possible fuck ups with the IMU company that they sourced stuff from, but that's just what I could see when probing my dead trackers for errors. Right now the slime team is currently in agony with the US FCC due to someone getting pissy with papers, they are working hard to fix there fuck ups and the community team are helpful when your shit breaks. just takes a while (thanks US customs :3)
Yep, ordered in Q1 2022, still waiting, now hope to have them in Q1 2024 but hard to keep hopes up just to waiting for the next delay update to come down the wire.
i know the video was months ago, i had no issue with the setup aside from me not knowing what to do, but im now using slimes and never used the body proportion bs! just ignored it and it works like a charm for me, just wished more standalone apps were able to use this feature like blade and sorcery nomad or more, i will say ofc the wait for a big issue, but after getting it, i really cant complain for what ive got
I certainly can say since I have experience. It will take them a long time to get you the trackers. There is a high demand and very little supply. They doing the aseembly all by hand so there's a limit to how many they can push out. I waited 2.5 years for my trackers.
Hey!, just to tell you those cheap ones are actually five for that money, which considering the tracking i've gotten out of mere manual calibration, it's genuinely amazing for the price.
5:18 not a big deal for this specific instance but iirc certain blurring tools can be reverse engineered to recover the original info. recommend blocking it out entirely just in case
Thrill you need to replace that head strap with BoBoVR M3 pro battery extension strap and OMG it changed VR gaming for me!! My brother has your strap for his quest 3 so I compared them both and BoBoVR is far superior! So much more comfortable and I can legit play for hours comfortably.

The slime knows where it is at all times. It knows this because it knows where it isn't. By subtracting...
Still surprised that Meta doesn't have its own IMU trackers, it would instantly solve all their leg problems
meta doesn't believe in legs
because meta is a faceless soulless corporation that doesn't believe in human expression
@@bongwatercrocodile315yeah they do?
They just believe it should be expensive. Look at Quest Pro (face tracking)

Just have a shortcut button and yaw reset takes just a double tap on B button , super fancy when dancing and need to yaw reset ;)

You don't need to do the autobone/automatic proportions dance each playsession, because people's body proportions don't change. Only the automatic mounting calibration needs to be run each time, which only takes a second (the one where you squat).
So no hula dance necessary, once you get your proportions down to your satisfaction :)

I ordered Slime VR (7+3) in March '22
Original Shipping date was the end of August' 23
First delay to end of September '23
Second delay to November' 23
And now with the last post update they got delayed to the end of December '23
I am a very patient person, but if it gets delayed one more time, I'll cancel the order...
Yeah, that my experience with Slime VR so far 😢
oh i already canceled it and made my own. got a 3D printer and the parts for literally the same price, but now i can learn a thing about them, got a free printer bascially and am able to fix whatever breaks. DIY slime is the way.
Hey, you still blame developer for unseen problems like FCC and Corona? You didn't even look around how many people are happy with SlimeVR? Then you should have more trust and patience. They even found new problems and make them even more better. You will get improved version at least.
@@mrdummy_nl uhm, where did I say anything bad about the developer???
I am keeping the order mainly because I got other projects to tend to, and Lynx R-1 is still being shipped out in batches.
@@mrdummy_nl are you okay?
I've been using SlimeVR (via phones) for about 2 years now, and it's been amazing! There are some downsides to it, like how often I have to recalibrate, but overall, I love it! Thanks for the new video, Thrill!
If the 16 dollar chinese trackers actually work fairly well, it's going to take VR chat into the future overnight.
I ordered a set that looked just like that on Amazon and never received my package. I looked into it and it appears I got scammed.
Just tried them, they needed serial to usb patch bc they used counterfeit serial chips. I can't complain for what they are tbh.
@@FAKEAXISwhat are they called
@@FAKEAXISwould you say they're worth buying? If so, how many trackers should I get. I play vrchat, and I don't do nothing crazy, just want to express myself without having to speak.
Yippee the slime revisit! Ordered mine during the initial crowdfunding campaign and I’m so excited for when mine finally ship home. I’ll finally be able to join my full body friends in VRC and stare at a mirror all evening lmao
Yo thrill i appreciate you using part of my video about my old phone full body .You're amazing
like any other full body tracking method, it’s a bit wonky, but I can’t lie. The open source nature of it is insanely cool
Awesome video on an incredible technology! Great editing and presentation.
SlimeVR has improved dramatically since the last video you did on it, for sure. There's things regarding setup and autobone that still need to be tweaked (autobone can be just wiggling around as long as the heels are planted according to the dev who made it, and animations will be added for simplicity), for sure, but overall it's way better than back then - that flashback sequence made me laugh, as well as the Level 99 Autobone bit (I got assigned that role in the discord server!)
This is really giving me a nudge on showing all the tips and tricks I know about SlimeVR, so thanks for that - I really want people to have the best experience they can with these!
Much love to both you and PHIA!
Always happy to see you being so engaged with SlimeVR. Much love!
woah, wild to see your name again, hope all is well
but yeah this video was awesome
still super excited for my trackers .... well when they ship ;~:
The wiggle dance killed Z
@@a_british_lass_stream_archives I just saw this now, but yeah! I'm doing good, I am actually working on my first commissioned avatar based off of Deira! It's very cute, kind of a gothy build.
@@ZRock35VR oh thats brilliant, i still need the funds to comm a avatar from scratch of my sona, unsure if you've seen her or not, it's been months my memory is foggy
i have close to 7k hours in VR but i could never justify buying trackers and everything just for FBT (ive only used oculus headsets), this gets me very excited for the future of FBT im glad you covered the good and the bad.
They need to make all in 1 suits for tracking and vibration and stop this nonsense of strapping together 8 units. They can make different tier suits for preffered price points, medium priced being likely most sought after.
It would be cool to merge slime tracking with an xbox kinect. It can roughly estimate your position in 3d space, so it could be a continuos calibration.
You could probably use the FaceID sensors on an iphone to get better accuracy. It's sad that no other phone brands have implemented a similar sensor.
Edit: Actually, I looked it up and apparently the company that made the sensor for Microsoft was bought by Apple, who used it in their FaceID sensors.
I really like the quality of Thirlls videos, he goes into so much detail and cares so much. 😂
That crazy part is, I know someone (you actually showed them at 11:13) that is working on a next generation prototype using IMU's that are newer then the retail SlimeVR trackers that are newer, that is exciting.
What is also interesting is the failed units you have. The same said person I mentioned above constantly gets completely faulty units they must discard.
The SlimeVR setup wizard is nautical miles of a colossal improvement for ease of setup, but the calibration is still per-person and too specific, so the product is not great to share the Full body VR Experience with a family member, friends, at a convention, etc
SlimeVR deserves to become the king of accesible FBT, but they should keep working on that setup wizard, and turn it as plug-and-play as possible
UA-camrs who timestamp sponsors are underrated immediately.
I just finished building mine a few weeks ago and I love finally being able to MOVE! They work pretty well too! 😊 Glad to see you revisit slimes and talk about them again!
Oh, you can export your proportions so you only need to do it once and then just slap it back in woth the file it gives you
11:32 the slime clones need a video immediately
I built my own Slime's over a year ago and I still use them. Im actually getting ready to upgrade the IMU's within the week. But All in I first built mine for less than 50$ and I couldn't be happier
Nice video. I’ve been waiting on my trackers for a couple years but it’ll be worth the wait. The devs have been very open and honest with all the issues they’ve encountered. Thanks Thrill!
Vive made an Instagram story that said something was going to be announced on the 28th. It had a digital outline of something that looked like the inside out tracker. I’m pretty sure that’s when it’s coming out in a couple days. I’m definitely going pinky up into that. So you’ll have to throw those in your comparisons as well!
Calling them inside-out trackers doesn't really help distinguish them from existing Vive trackers as those are also inside-out.
Better to say markerless inside-out vs marker-based inside-out, camera-based vs photodiode-based, or camera-based vs lighthouse-based.
I am very sceptical of marker-less inside-out trackers for FBT. Each tracker knowing where it is in space isn't enough for FBT - they need to know where they are relative to eachother and the headset.
That relies of them all seeing the same parts of the room and sharing "landmarks", or seeing the headset, or the headset seeing them, or each tracker seeing (and somehow being able to recognise) at least one other tracker.
The Quest Pro trackers that work in the same way reportedly exhibit some weird behaviours and problems and they have a clear view of the headset most of the time. Something attached to your feet doesn't have that luxury.
I'd expect HTC are going to market them more for tracking a single arbitrary object like a camera for the purposes of virtual camerawork.
@@zig131 it's definitely an interesting problem that I can't wait to see how they plan to address. My best guess is that there will be something like a calibration paper or tag which you would point all trackers towards and they reference in relation to that, but it still wouldn't solve the issue of misalignment with the headset itself
@@zig131 Yeah, that's just me misquoting HTC's words "Self-Tracking trackers. I don't really know what you're going on about in the paragraph, not that tech savvy. However here's some words from what looks like one of the people working on it.
"1 dongle for 5 trackers. All 6dof uses IMUs. It’s just easier to use. Much more accessible. In an ideal environment, inside out HMD tracking is as good as SteamVR. We built the new self tracking trackers so there’s a solution to tracking outside the FOV of the headset, without needing external sensors or base stations. Remember lighthouse is still limited to 10m*10m."
Hope that helps.
I ordered some diy slimes off the marketplace in the slimevr discord and they got delivered in under a month. They use slightly worse imus (BMI160 compared to the BNOs in official slimes so more drift) but the tracking quality is insane. With 11 trackers its so hard for my friends or most people to spot the difference between me and vive users. Love this project thanks for covering it again
Great video! Thank you for testing these thoroughly
Hello Thrill!! Thank you for your contributions to the VR Community!!!
As someone not in the slime community, but with Both 10+6 slimes, and 3 vive trackers, I can say this is a fairly accurate comparrison. Personally, I still use my Vives more often, because there's less trackers, though i will say the slimes are more comfortable (they're so much lighter and thinner!). I've added just one slime as a chest tracker to my daily use setup, and that works great. It wouldn't take many more to add arm tracking, but trying to get everything set up absolutely can be a hasstle.
I also want to note that I didn't have any issues with any of the 16 of my slime trackers, at least, that i've found so far.
As Thrill noted though, the biggest issue was setup time.
When i got my Vives for the first time, I was already in VR, and it took maybe 15 minutes to get them up and running, including a mute friend of mine walking me through the in-game settings for my first time in full body.
When i got my slimes, it took me maybe an hour to pair everything and get the setup done. I then spent another two hours messing with calibration trying to get it to a nice place so it doesn't feel messy (and sometimes it wanted to be sideways, which was very weird, but i fixed it in the end).
Now that both are set-up, It really does come down to a preference of lighter weight and no occlusion vs time to put them on, and i am a lazy fucker at times.
Overall, I can and do thoroughly recomend them to basically anyone. They're definately worth it.
I'm so happy to see slim get this huge upgrade and stable tracking, i hope everyone can get them and enjoying it, have a nice day people! 🤗
Excellent video, so glad to see a revisit to the SlimeVR trackers!
6:58 bro just did the club penguin dance over and over again just to calibrate some trackers
The slime trackers shipped again today! They were held up in customs then reviewed by the FCC and had to be recertified and reshipped but in theory they should be out to backers soon.
They also contracted with a manufacturer to get faster and more consistent boards built. Fingers crossed this makes everything from shipping to QA more reliable.
They're really good at updating us on the Discord server
The trackers arrived just over a week ago.
I got the set with 5 trackers and 3 extensions. Chest extension to waist tracker, thighs, then ankle trackers with extensions on feet.
The good: Simple to recalibrate just stand feet close together facing forward and double tap the chest piece, surprisingly accurate tracking and people can't tell it's not vive or tundra, doesn't need lighthouses so they're portable, straps are comfortable, AMAZING BATTERY LIFE VS COMPETITION.
The annoying: Initial setup takes longer, if smaller straps for extensions shift I need to recalibrate, needs more trackers for the same amount of accuracy, if a tracker gets turned off by mistake I have to take them off lay them all flat and reset them.
Recommendation: Go with the full set and don't use the extensions. Still cheaper than a pair of lighthouses with the other trackers and you have greater movement range around the house due to not needing the base stations but if you already have the base stations go with Vive or Tundra.
Just got mine yesterday 😁 Ordered mine on December 1st. Them delays are no joke
Mine is coming Wednesday, I might explode
@@UczuciaTM Calibrating is a pain in the ass. Just a fair warning lol. I was doing the movements for hours trying to get it accurate as possible. I eventually just UA-camd a much simpler way
@@xtremeninja8707 they came a day early and I got the tracking to be decent enough!
I was an early buyer of SlimeVR, over 2 years waiting for mine so I DIY built 2 sets in the meantime. They're pretty great but the better IMUs in the official Slimes are something I'm looking forward to
I have built mine on the BNO085 IMU with the mag it autocorrects and is perfect.
Man if I actually played social games and liked talking to people these would be awesome
I'm genuinely considering it. The prices seem fair for the quality and the quality looks pretty worth it by itself. Glad to see Slime coming back again
If you're ok with some waiting time (all actual orders are planned to be fulfilled by end of April so not so long to wait anymore), it's definitely worth it, especially if you don't have base stations!
@@naomie2680 Thanks for the confirmation! I've been stuck on VR Chat for a while now, so I think I might invest in it for the craic, it helps that I don't need to buy base stations alongside them-
I've got my parts on the way, and with the amount of electrical parts I have laying around, 6 trackers only costs me about $110 USD.
If you've got any experience with electronics and parts lying around, Slime might be even cheaper and easier for you than anything else.
Ooo! Exciting, I'm definitely gonna solder up a handful of these and give them a spin, I even have like 90% of the components in stock, I'll just have to order the unpopulated PCBs.
I'd dig into that DIY path, building stuff is way more fun that fighting customs for international shipping xD
These look like they could be vastly useful for motion tracking in creating 3d animation, if that's an available option.
So tempted to sell my VIVE trackers and base stations and just build Slimes.
VIVE trackers are just so hard to set up in a way where they will give you even decent tracking.
Hey man! This might be a super dumb question, but I'm new to this side of VR so bear with. Is full body tracking just a way to track my body in something like VRChat for aesthetics? Or could I use my actual legs to walk around in some games? Because going for a run in Skyrim or moving around in Blade & Sorcery using my legs would be awesome! Cheers :)
I am so excited for when I DO finally get my SlimeVR but yes, I have had them preordered since December of 2021 lol
They should pair it with the quest inside out body tracking....just like they did with the quest 3 controllers
Not sure what are the odds but I built my own 7+3 and they just worked first time🤪. I had spares too. Followed instructions and never really soldered b4. Followed UA-cam guides to solder correctly. After the last update its worked great! Highly recommend DIY.
I feel like the final solution is just a camera with a trained AI that takes video feed and turns that into full body tacking data, there's been a few studies already.
That really shouldn't be the final solution, at least in my opinion
I currently use a Kinect sensor for full body tracking, and while it works well for facing the sensor directly, turning doesn't work very well, even with the algorithms it has for dealing with that
Trackers that are able to track themselves are for sure the way to go, since they don't have to get calibrated or anything, they just get turned on
@@davidlewis2171 Generative AI is a powerful thing, kinect doesn't have that, it's old tech. AI can do so many things, look at anything from the 2 minute papers channel like the ones that generate procedural animations, or other that track movements perfectly in 3d with just a video.
@Raulikien That is a fair point, and I agree that the algorithms for determining poses are getting better all the time. However, the other half of it is that while you can have a camera doing that for you, unless the camera is on the headset itself, you're very limited in where you can use FBT. This isn't the case with standalone trackers, where you could use them in any room. With a camera, you have to stand a certain distance away for it to be able to track your whole body.
I love following the technological advancements with full-body tracking, but I have no reason to buy any cuz I’d never actually use it 😭
Really good review, im really happy that you stay transparent in this video.
Thank you for addressing the shipping problem If I had known that it was going to take so long I would seriously re contemplated other options. I order mine march 19 2023 and I’m personally estimating that they may arrive around jul of 2024 hopefully
I NEED that autobone dance to be made into an animation that I can put on avatars, it looks too funny
As a VR dancer and content creator coming from 10 months of using camera tracking to BMI160 14 points! To now BNO085 IMU's all DiY. I have landed on 12 points as the golden point, the neck completes the chest (chest+neck = 1 vive chest, waist+Hip = 1 vive hip).
I only do porportions once (got tutorial on it), since u dont grow ;) Also highly recommend straps with rubber on the inside (Trilancer 12'
YAY FINALLY VIDEO IM SO HAPPY
every video is a BANGER
Slime being twice the work for half the price for similar really good result sounds like just my kind of thing, specially when I can build them myself, it'll be x4 the work for ¼ the price of a full body set, i'm in
I made a friend in VrC and he told me that he bought Slime a while back and can't wait for them to arrive. It's been a year+ since he told me and they still haven't arrived yet.
I would love to get me some slimes as well, but if I have to wait a year+ until they arrive then that's just not for me sadly
You’ve convinced me I’m buying
(7:20) FINALLY I KNOW HOW TO DO THIS PART, I was touching my feet with only one hand and was wondering why it thought I was like 9 feet tall. THANK YOU SO MUCH!!!
An exoskeleton that measures joint deflection is another FBT option. You could also add large feedback systems to such a thing as well.
I wanna know what the clones are so I can look into them myself
You know it's good when the video ends with a presentation in Cybertronian
To me, the most important thing is I think IMU based tracking will be the future of VR. Not as it currently is, but Pico is working on IMU tracking, Valve is working on IMU tracking, even meta if I remember correctly is working on body position estimation with no or almost no tracking. Laser solution definitely works best, but they're a goal, it won't move further from there. At some point I do believe IMU's will reach that point.
By the way, magnetometers (included in the IMUs) can be used to completely negate the drift, but you need a magnetic free environnement which can be hard to achieve sometimes
You’re the GOAT thrill ! Thank you for the update 👏
Where should I look to try and set this up with some joycons? I have like 4 laying around and 1 of them has a broken joystick, so I might as well put it to use.
Slime VR being so inaccessible for so long is the reason I personally jumped onto the HaritoraX Wireless trackers.
I’ve been with the HaritoraX for a few years now, and it’s worked decent to pair with the Quest and not need to worry about basestations. I’d love to move to something with far few cables and wires though, it’s easy to get everything all tangled up haha
The power of open source! I want more people to see this so they can understand what it trully means for communities and customers to get a mature open source hardware and software and invest more money in such projects :3
i ordered a slime about 2-3 years ago - i still havent got it but im so hyped forit .....
cool to see my world at 12:42 lol
I got my diy kits within a couple weeks
never thought i would see my trackers in a Thrill video even if its for a few seconds xD
Please do the Oculus Rift cv1 body tracking!
in the video 2 years ago, I seem to remember you did something with the software. Did you try the Mocopi with the Slime software ?
I might have to look into full body tracking. Just got full bhaptics. Now down the full body tracking rabbit hole. Fck this sht is expensive.
second backer on the slime project: for my set that I bought, 2 of them died within 4 months due to a: with HEAVY drunken use along with horrid temp changes in my room, and b: possible fuck ups with the IMU company that they sourced stuff from, but that's just what I could see when probing my dead trackers for errors.
Right now the slime team is currently in agony with the US FCC due to someone getting pissy with papers, they are working hard to fix there fuck ups and the community team are helpful when your shit breaks. just takes a while (thanks US customs :3)
I just realized I've been waiting for my SlimeVR trackers for over 2 years, kinda forgot about them tbh
Man that preview at the end of your video has me hyped! I cant wait to see what you created
Finally, a vid that doesn't revolve around quest 3
11:12 I have no idea what site that is and would very much like to know.
a mix between something like tundra and slime would be the perfect fbt with our current technology but i dont know how wed achieve that
much love all!
So did the eBay ones work?
Yep, ordered in Q1 2022, still waiting, now hope to have them in Q1 2024 but hard to keep hopes up just to waiting for the next delay update to come down the wire.
What model is your avatar? It’s really cute! Is it a rindo?
The updates are great and consistent.
i know the video was months ago, i had no issue with the setup aside from me not knowing what to do, but im now using slimes and never used the body proportion bs! just ignored it and it works like a charm for me, just wished more standalone apps were able to use this feature like blade and sorcery nomad or more, i will say ofc the wait for a big issue, but after getting it, i really cant complain for what ive got
I certainly can say since I have experience. It will take them a long time to get you the trackers. There is a high demand and very little supply. They doing the aseembly all by hand so there's a limit to how many they can push out. I waited 2.5 years for my trackers.
Hey!, just to tell you those cheap ones are actually five for that money, which considering the tracking i've gotten out of mere manual calibration, it's genuinely amazing for the price.
5:18 not a big deal for this specific instance but iirc certain blurring tools can be reverse engineered to recover the original info. recommend blocking it out entirely just in case
Thrill you need to replace that head strap with BoBoVR M3 pro battery extension strap and OMG it changed VR gaming for me!! My brother has your strap for his quest 3 so I compared them both and BoBoVR is far superior! So much more comfortable and I can legit play for hours comfortably.
Kkcobvr q3 and bobovr S3
Are better now
I look forward to seeing your review on the $16 trackers! xD
WHERE AND WHEN CAN WE GET QUEST BENCH?!???!!!
