Valem I love your videos! But I should say that with a little work one could use your custom hands tutorial to create hands, then hide the rigs hands and have the wrists match up haha. I'm sure your pateron is a much better solution though if anyone wants a quick solution I found that worked nicely
@valem watching you code the hell out of this, is like watching some kind of renaissance master paint the Mona Lisa. How the hell did you get to this level of confidence? Are you figuring out all those lines yourself? This is sometimes so incredibly complex, and after years of trying to learn C# I couldn't do 1% of what you're doing each episode. Just mindboggingly mindblowing. LOVE you.
@@ValemVR Yeah I get that of course. But to come up with that logic in the first place - no matter how much time you got - is still incomprehensible to me. Pure genius. And on top of that so generous. If people like you would run the world, everything would be alright.
This tutorial is great, as was part 1. The only real problem is that you have used a completely different structure on your rig to the first video. It does not appear to contain the constraints you made in part one, but instead, three other game objects named HEAD, LEFTHAND, RIGHTHAND. This causes a huge disruption in the consistency and flow of information when the video indicates it's a continuation. Thank you for the video though, it is very much appreciated.
Man, this whole series has been amazing stuff, I have been waiting for, for so long. I love this series. If you ever get time would love to see you do a series if possible on fps arms using this, I got the arms working but hand animation requires a different approach. Also, put the cherry on top in the form of Body physics for the VR body lol. Yeah, I am going to be that guy, but still gonna ask lol.
When i add the animator avatar, my mode just flys towards but past, were it should be in correlation with the head set. If i start without adding the avatar it snaps to were it should be but when i add the avatar it just stays still even if i move the camera, ik targets or controlers
I found one small problem, my hands don't align because the rig is unable to stretch, so it's assuming the player is VERY short... This makes it look super funky...
Can you make a tutorial on how to track full body legs in this using vive trackers? I get that we have a walking animation, but I wanna move my legs freely
Could you attach a second set of hand controllers to your feet to track foot and leg movement? Thanks! Great video. (I know I could get the Oculus pro if i could afford it for leg movement)
Same thing is happening to me. I think it is the hands interfering with the Raycast. I tried having them ignore raycast, but it didn't help. I would love a solution to this problem as well. :)
Thank you very much for this great tutorial. I'm a VIVE user and use STEAM VR instead. I found out that if I follow steps in the video, at the end, my Robot would continuously fall under the ground. This got on my nerves. Could you give some solutions to this? Thanks a lot:)
I didn't notice that the issue is actually in this video and thought it was my project that was the issue. But as can be seen here, the hands curl up, or bend inwards a bit. What's the deal with that? And how would you go around solving it? The hands are not bent similarily in the animations used from what I can tell. And this is quite breaking the whole point of only animating the lower part of the body.
Hi Valem or anyone that can help, can I use the IK hand setup while also using the animator for moving the legs? Because when I add an animator controller with an avatar my IK hand setup stops working. Not sure what to do to work pst this. Thank you , and awesome tutorials!
I can't move Robot Kyle by selecting him when in game mode like you can. I can only move him if i move the OVRCamera rig. When i start game mode, he also jumps a few spaces ahead of where i spawned him. And I've done all the code, but his feet still go through the floor. And i went back over part 2 just in case i missed something, i can't find anything. Can you help me? EDIT: Nevermind, I had one line of code wrong, and i didn't delete the OVRCamra rig from when i watched part 1. Without that camera, its working just like in the video.
I am trying to create a player with SteamVR but I cannot add the walking animation to my Robot Kyle, I completed the first demo successfully...to my knowledge. I am not really certain what I am missing.
This worked perfectly, thanks Valem ! But still how can we move while having a native standing height over the ground ? I mean, the body follows the vr camera, so the position of the camera define the height we should have while standing. I was thinking about coding a raycast from the vrcamera to the ground, if the size exceed a certain height value, resetting the heigt of the vrcamera to that height value. What do you think ? Is this the best way ? Thanks
I know nothing about coding so could you please help me and my friend on how to make a model from scratch that works well in vr. (That has arms a legs.)
Going through this tutorial, I noticed that with a walk animations and the Robot Kyle model... EVEN with the upper body mask, the hands still curl like they are being animated somehow. If I turn off the VRFootIK script and the animator, the hands return to normal. Any idea as to why this is happening?
@Plastic Bag Just as a FPS game allows you to walk (lower body) & Aim (Upper Body) at the same time using masking, the same should work with any body part including hands. You don't simply swap an entire animation just because you don't know how to mask something.
Hello again I just had a quick question,when I import the walking animation from mixamo to unity I dont get an animated walking preview only blue caution symbol and im not sure how to fix this as I've tried things I red online but they haven't solved my issue
I tried to create the walking animation and it broke my character's rig, making the whole body fly off to the side, and now after stopping that it says this - UnassignedReferenceException: The variable headConstraint of vr_rig has not been assigned. You probably need to assign the headConstraint variable of the vr_rig script in the inspector. UnityEngine.Transform.get_position () in :0 vr_rig.LateUpdate () (at Assets/scripts/vr_rig.cs:45) even though the rig works regularly
When you apply the avatar, the tracking is horribly off center and the model won't match up, removing the avatar fixes the issue but we lose animations D: any fix so far? @Valem
Are you able to capture and record this kinematic data for later use? Like have a performance in VR. Record data. Have that data played on another model or animator.
Hi no worries yes you can use this and record the frame zt runtime using in an animation using this : github.com/newyellow/Unity-Runtime-Animation-Recorder Its quite simple And you will have yourself your own motion capture studio 😊
At 10:04 the code entered is related to right foot rotation (before copying to the left) - I have this copied exactly but am getting a red underscore on the last written "rightFootRotation" that reads: "Argument 2: Cannot convert from UnityEngine.Quaternion to UnityEngine.Vector3" Anyone have a fix for this? Thanks!
Love your tutorials. I followed this one (multiple times) but once i set the avatar on the animator to be the robertkyleavatar the IK does not work anymore and the whole character freezes in its current position :( could you please help?
@@ValemVR I'm using Unity 2019.2.17f1. Also, do you know what could be the issue that my hand tracking is too low? its perfectly fine in Oculus. Thank you so much for the answer
@@ValemVR Yeah. If I put my hands in front of the VR headset for example. In Oculus I see the controller right in front of my eyes. Yet in unity the hands are at my chest :/ I can't figure out why.

It's really confusing and yet I'm wondering why nobody else noticed. Looks like it's an improved version of Part 1 to me.
I would recommend using a layermask and uncheck the playerbody layer.
