Can you screenshot your scene and upload? Maybe one of your object sidebar/menu as well?
you have the proper lighting I assume?
AE any objects cloned or instances?

Did you look at your task manager and see how much memory is actually being used?

Also, when you post here there is am option to upload files directly ("Upload files" link button). So you can put them right here in this thread.

Looking at the density here, I think I may have exported from zbrush with too many polys... Maybe I can re-export, re-rig, and get the animations still to work. Will try this tomorrow and if this doesn't work will send project file. Many thanks.

> Btw what's you system CPU RAM size?

32 GB. Currently going through the process of retopologizing and re-rigging. As you said, might be more of a cinema issue than a centileo issue, in the editor I assume there is one level of memory requirements but when you press render and C4D "assembles the scene for render" (not sure what this is called in practice) I could see where exploding memory could be an issue. I do machine learning stuff too and exploding memory can be an issue there where you change a couple of parameters and the whole thing comes down, with the solution being "lower the resolution/model size" etc.

Thanks for CentiLeo, really nice project.

This issue was fixed by lowering the poly count on the models I imported from zbrush. As you say, probably more a C4D issue than Centileo. Everything is working fine now.

I am doing machine learning in a separate application, I use python with GPU integration. I prepare and train models on a freelance basis for companies. I would like to use it for EG mesh generation, texture generation, or motion capture from 2d video, but there's not enough time in the day. Soon enough you will be able to point at a 2d picture or drawing of something and say "now generate a mesh for this". Or take a clip of someone dancing in a video and say "generate animation" and it will add that animation to a rig that can then be attached to other models. Although if I was going to make a plugin to do this, I would probably target blender at this point.

I did see you added matrix color attributes in the update, thank you sir!

I am working on a spaceman shootout sequence that is coming along nicely.

This isn't my work but saw this today and thought to post it in case you are wondering about some specific example of machine learning for mesh generation -- it is rapidly progressing, so I expect to be able to use this in "plugin form" at some point in the future: https://twitter.com/jasonyzhang2/status/1467949093829988355.

> How many polygons in total? Maybe your loader adds polygons each frame without releasing memory for ther previous frame? If that's some kind of Alembic it looks strange. What is your RAM size and what's the memory consumption in the Windows task manager during the PV render?

170k per model with alembics for the animations. I reduced model polys to ~17k and applied the same animations and it worked. Ram usage not that bad, when I was rendering before it would immediately crash with the memory error, but now it's fine.

Here is the animation I was working on.

Still needs a couple scenes at the end and one at the beginning and to add audio, but you get the idea. This was all rendered with CentiLeo. One question, in the hall scenes, there is a lot of flickering on the lighting and reflections from frame to frame. Any idea what might be causing this? Should I increase the generated samples rate? I currently have it set to 1 sample per frame (compared to ~3 which I used to use, but of course this takes 3x as long). Been going hard on this for a couple of weeks.

Ahhh, the denoiser, that makes sense. Will try increasing sample rate and turning off denoiser and rerendering.

Trying with 4 samples and no de-noising and I notice there's a lot of variation in the lighting where I wouldn't expect from frame to frame. I have importance sampling turned on on the emissive light material, could that be doing it? Starting to think it's something to do with my scene. I'm attaching some screenshots with examples. Maybe I can find a temporal de-noising method or something, not sure what the latest state of the art is on that.
