LuxCore Render for Blender Crash Course | Download and Installation
Вставка
- Опубліковано 31 лип 2024
- This is the first of a series on the LuxCore Renderer for Blender plug in covering the download and installation of the engine as well as uninstalling old versions, basic settings and some general information on the engine. I will show you how to activate the engine, activate your GPU settings, quick render setting presets and how to enable the light tracing method. This is not a full crash course on the engine as there is a ton to go over but this should give you a starting point.
Make sure to subscribe to the channel for new videos on this engine as I go through all of the facets of the engine.

Brilliant video, so well thought out, perfect speed and really really informative.
Very good, congratulations on the initiative. It will be great.
These are amazing! I'll work my way through them, the effort is much appreciated. Subbed immediately
Thank you! You’re amazing!!!
wow! this is not only free but also open-source! gigantic respect to all the contributors. this is very cool.
Many Thanks, DJ!! Best Wishes
OMG, I am so gladful that you made this!

Excellent Video.... Very useful info with easy explaination. Thank you.
Thanks for the great stuff here.
Hello ! Starnge, I don't have all the elements you have in the shadow of the disco glass ball. Light tracing is enabled
works fine on Mac fwiw - macOS 10.15.7, Radeon 5300M 4 GB, Blender 2.91
Update: 2.5 BETA 1 appears to actually not resolve all the AMD GPU issues. Apparently the viewport had been set default to CPU with a different setting. I will be testing out some items to ensure amd users can use these newer builds.
Great video. Btw, theres a way to mix cycles and luxcore passes?
@@hugoantunesartwithblender yes- you can render assets as layers then composite together. I would recommend using Natron. I will be working on some Natron basics videos in the future.
❤
Yes!
Indeed!
I hope that the Blender guys are working close with the LUX guys.
I would like to see tighter integration.
I havent had much luck with using my older Blender scenes so I guess its more than a matter of hitting render and hoping the materials are okay. Its still a hell of a lot more bug free then ProRender right now
Sometimes the entire API is rewritten. It often is the case that repairing nodes is essential. But baking out textures helps too.
Thnak you...
Of course!
Interesting ill take a look at this engine, the lighting looks amazing, but most probably ill use it for final renders or just the lighting passes and then combine it with render results from pro render.
It is really a great engine but has a lot of stuff that's a bit quirky. I'll be releasing 1 or 2 videos a week so I'll try and get you up to speed as quickly as possible.
ive tried ProRender but it doesnt like my intel and nvidia setup. A lot of the time it will leave huge areas only half sampled.
@@TheUninstaller2000 which render option are you using? 2.0 (New FULL setting) or Legacy (Old FULL setting)?
Maybe you should also make a tutorial on how the denoiser works. Because it is a bit confusing for most people I think and it is also an essential function.
I'm going to be going into detail on many aspects of this engine. It's very complex and powerful. I'll work on this for the future.
Thanks for these, I tried to join the forum but no response email. Is the discord more busy? Hope this project does not die as those caustics are the best. Goood work and much appreciated.
Not sure…. I hope it continues being worked on as well. Thanks!
In addition, regarding those who are working on Mac products, LuxCore 2.3 was working fine in Blender until Mai-July 2020. With MacOs Catalina, some big updates arrived around July and September and the "Metal & Open Cl & graphic drivers codes" changed. Upgrading Blender to the latest version and installing LuxCore Render V2.4 was not enough to solve the problem in 2020. Since this January 2021, Apple reworked a lot based on Pro-Users feedbacks and it appears that actually it solved some issues. I've just tested Blender 2.91.2 and LuxCore 2.4 (both Mac OS 64) It works now but remain less stable than Radeon Pro Render 3.0.8 with Blender here. Definitely, I wouldn't recommend for any 3D lovers, fans, or artists to choose Mac Products fro 3D. The value between the price and the benefits on a daily use isn't worth it if you compare the speed, the reactivity with PC Windows. Actually, I would switch from Apple to Custom Build Machine with two Nvidia RTX 3090 ;))) Keep it up guys with your passion. Thanks.
Indeed. My build is has a threadripper 3960x with rtx 3090. Very good value.
I have Mac and pc and am platform agnostic. both are custom built for their purposes. I think if someone is going to dish out that much money for either they should already know what each machine is capable of. blender utilizes computer "areas" for different purposes, many wont make a difference. i would never render on my MacBook and I would never attempt a heavy video edit on my PC. in fact I have a separate opteron PC just for Maya because it was coded on one and im superstitious :). in general not knowing the tool for the job is bad all around.
AMAZING TUTORIALS! PC specs=?
CPU: Ryzen 3960x
GPU: RTX3090 (at the time of this tutorial it was 2XRadeon VII)

How can I get output without background?
in blender
Jump on the discord. I can do screen grabs for you
hi. i use gt1070 and using cuda for rendering doesnt give light tracing effect, only on CPU it works. and denoise destroy picture, make it blured and ugly. what do i do wrong? need help pls.... i wont use luxcore but cant....
Light tracing used CPU even if the GPU rendering is turned on. Make sure that you have both render devices turned on.
Denoiser in Lux is my problem number one.cycles render is now pretty fast and get Nice and sharp results.luxcore Has better lighting but is so slow refresh time is 5 seconds in blender...and denoiser completly destroy details in render
I already had my scene created in Cycles with lights and all. And then I installed and used LuxCore and still get the light blue on the entire scene. I'm using Blender v2.92.0
How do I fix that ? Im using OpenGL on a GTX Nvidia 1070-Ti because for some odd reason CUDA doesnt want to work properly. And yes I did activate Devices button :)
So i left it on OpenGL and using the GPU and it works pretty fast, Just wish my scene I created would come to life, instead of the all light blue......lol
The lighting I used in the scene when using Cycles are in the Nodes using IES files and Nodes specifically for Lumens and Kelvin. Im controlling everything via Nodes on the light-bulb.
Jump on the discord and someone can help you
This should be default stock in Blender. Screw damn Cycles. Devs are too busy with stupid grease pencils and geonodes instead of proper rendering quality. Unbelievable. Thank you so much for your tutorials, I really need this for work as I render a lot of alcohol/drinks/bottles in Blender and this is a game changer.
I agree but I’ve heard that Blender devs have some kind of beef with LuxCore. I dunno.
Aha. Yes. Fun plugin. Looks cool. I am struggeling with noise though. I have lots of spots in the renderings. maybe i need more samples. hard to guess. but the denoising in the viewport looks way better than the denoising in the render. very weird.
Turn on Denoising checkbox in your render settings and make sure that in the compositor you view through the denoise output
@@djtutorialscgi yay! that sounds like the solution yes. ....just not sure how to do that yet.... i watched your tutorial about glass, dispersion, caustics.... but you didn't cover it in there.... i will look further....
@@djtutorialscgi aaaaah ok ok i found it. in the render window you can select the DENOISED view layer. i seeeeee. cool, cool.
but ehhhm,... how do you make sure when you 'render animation' it saves the denoised layer in the folder? ....i'm not sure it does right now....hmmm
ok. add the 'denoise' node in the compositor, simple! got it....
Using Blender's Eevee or Cycles I can import a vertex painted model and render it by adding a Node for Vertex Colour (or similar name). Would this be an issue using LuxCore? I'm assuming I can still use Nodes and then render using the Lux? No worries if you don't immediately know the answer to that. I guess I'll find out eventually.
There is an option to use Cycles nodes or LuxCore. Whether it’s supported or not is another matter. If you import your scene then check the box for Cycles nodes in the shader menu, you can see if it works. Not all nodes are supported though even through that method.
Also- I don’t use vertex color often as I tend to bake out the materials when using other engines but LuxCore might have its own vertex color node. Check the manual on the LuxCore website.
@@djtutorialscgi Thanks for your replies. Not that experienced with Blender so lots of learning involved.
Definitely. I recommend getting on the discord to share ideas and get questions answered.
@@djtutorialscgi Got LuxCore installed and I can confirm that imported models with painted vertices do indeed render fine with the addition of a Vertex Color Node.
Can I get a mirror download for the .zip file? For some reason when I download it, it keeps stopping at random times and it is marked "Forbidden". Is that normal or do I need to do some stuff before downloading first?
That’s weird. You’re downloading from the LuxCore website?
@@djtutorialscgi Yes
That’s really weird. Jump on the discord server for the channel and me or another artist can help you there.
@@djtutorialscgi I'll try some methods first. I'll join the discord if I can't really figure it out.
I got it downloaded! Apparently I can only download it via WiFi. Looking forward to luxcore rendering since I Iike working with glass materials.
When I try to enable the add-on, blender crashes (I use mac)
I would recommend checking their forums or going to my discord and asking there.
does thi work on blender 3.4.1?
You might need to check the developmental builds
Is that faster than cycles?
It can be!
Hi, have you (or anyone) take a look at Appleseed www.appleseedhq.net/? How it is playing in the render engines landscape?
Hi there- I installed it and took a quick look. Ended up with tons of interface and render errors. I will need to look further into. Join the discord server to share ideas!
@@djtutorialscgi I'm already on Appleseed discord channel. I'm also on LuxCore discord server. Appleseed looks like a decent render engine but the development is super slow, at least compared to LuxCore. I can't even run the latest blenderseed version on my Linux system. Like you said, If you look further into it and find something interesting, please let us know.
Anyone using this with Blender latest releases?
Yep
so are we working in blender 3?
I’m not %100 sure if LuxCore has a good release/dev build for 3.0 yet. I think they have a dev build but you can check
the idea looks great but unfortunately it is too buggy with my created scenes on cycles with an RTX graphics cards, some textures won't load correctly, other will render completely different than they do in cycles, and I mean like diamonds look red as if they were ruby jewels, character skin rendering wrong in only some of the parts, HDRi way darker than it was in cycles... I hope it gets better in the future but for now it is unfirtunately no valid alternative for me :(
I understand the issues- it uses more real world and professional colorspace with images which is why you are seeing the some of those problems with it being darker. As a professional, you’ll need to learn more engines like this to keep up so I would recommend learning it just for the experience. Jump in the discord and chat with other artists- each engine has its positives and negatives.
Cycles will get you used to shortcuts and cheats which don’t work in the “real world”. It’s a fantastic engine but to be a true professional, knowing others like Octane, LuxCore and ProRender will help you!!!
@@djtutorialscgi thanks a lot for the quick answer, I really want to use a better rendering engine than cycles, at least for some of my projects.
My current problem is that I'm mixing content from different sources, like characters from Character Creator 3 and jewelry pieces that a frined makes in Rhinoceros then I import them into Blender and often also other add-ons or substance for additional work and I'm not sure if I'll be able to make all of them together in LuxCore, specially the CC3 characters textures since these are already very complex and I wouldn't want to have to build them from scratch all over again for LuxCore rendering, not sure how to overcome this issue but I'll definitely try it, specially because the jewelry part is very important in one of my projects and cycles doesn't really do that work very well.
Anyways thanks for the answer and the hint to the discord channel, I'll try to connect and ask there for advice :)
Definitely jump on the discord- a lot of people will be able to help you out.
10:30 Why doesn't my work hit the ground?
Not sure what you mean
@@djtutorialscgi Well, I can do it Thank you for your reply.
@@djtutorialscgi I'm not very good at English. 😭
@@erebus7989 that’s okay. I’m not good at English either. Good luck!
