Hi vblackrender.,
I am writting the new docs now. At first there will be information about materials, projections and shaders. Just stay tuned, initial things will be out in the coming days.
I recommend to use R21! It's nodes are so cool and we have made our own nodespace for it.

Hi vblackrender., welcome here and thanks for warm words! Yes, you didn't know about CentiLeo because the shape of our features was too fluid and so no any adverticement... Implementation could simply change in any direction.

Currently there is an ongoing work to improve the knowledge about us, such as making an online documentation. This should help to gain more downloads.
Btw CentiLeo should be fast in darker interiors which are not very well lit. And right now there is development for particles/massive instances.

What version of Cinema are you using? The is a lot of attention on the new Cinema nodes starting from R21. Soon we will make them for S22 too.

Your questions are welcome!
The topic such as this is ok for images. Any questions are ok in Discussion forum (for some more general ideas that can be relevant to more people) or here (with questions specialy important to you).

Change Log: cntlc4d 0.591 alpha (2020 April 08) - currently for R21 only
[core] Fixed broken Absorption property
[cntlc4d] Fixed bug for lost frames during animation rendering in PV
[cntlc4d] Fixed bug with wrong geometry translation when IPR doesn’t account for some deformers (such as Surface Deformer and few others)
[cntlc4d] Fixed few bugs which caused some crashes.

I got several crashes while I was developing node editor integration for CentiLeo. Everything was done with Cinema SDK rules. Not too many places to make own bugs. When things were done for 0.58 the crashes during node editing work have ended.

But currently I still get random crashes when modeling (applying boolean operations, deformers, generators, bevels, etc.) while working in IPR with enabled scene auto-reload (IPR button with circle arrows and "auto" label). Will investigate further of course and fix other bugs too.

What operations were you doing before hang appeared? E.g. did you have opened IPR? Did you have enabled "Auto scene reload"?

Still not getting any crashes at this model. However, there are no textures there. Can you send them too pls? Eg. a link to email info@centileo.com

I have similar setup. Please, can you send me this scene and tell what to do to cause the crash? Does it always happen or randomly?

Hi Aimar, this is not a complex node, it's an ordinary one. So under some conditions this node was crashing? I am interested to know some conditions: what nvidia control panel settings, driver version, what GPU, what Cinema 4d build version (115 or 207)? Everything.
However, the bug may happen not on CentiLeo side, but on Cinema node side which is still not yet very stable (without CentiLeo).

which one? can you describe? is that always reproducible?

Keith, yes I know about this. Not very convenient at the moment with non-docable window, it was re-used from our Max plugin. Will try to fix this re-writting the IPR for C4D GUI controls if will be able to quickly develop particles / very massive instancing support.

Hi Keith! Welcome here! Thanks for hint... I always tested the plugins directory inside Cinema installation folder. But have now tested the directory located at "Open Preferences Folder". And it has "plugins" folder. It's like "C:\Users\User\AppData\Roaming\Maxon\Cinema 4D R21\plugins". I have copied "CentiLeoR21" from downloaded archive and it works too. Have you done it this way? It should be ...\plugins\CentiLeoR21

Proof

Hello everyone!

We integrate with Cinema Node-based GUI for materials and shaders in CentiLeo 0.59 release!
It works for Cinema R21.115 and newer versions.
Maxon Cinema has very cool Nodes engine which we are happy to integrate with! It's a lot more powerfull than Slate editor in Max.

Currently there is no yet converter from old CentiLeo materials to new Node-based.
Note that in these new nodes we have organized materials a bit differently:
1) Emission is moved from CentiLeo Material to a separate own material
2) Displacement is also moved to the root Output Material.

Attention! Must Upgrade to:
- Latest NVIDIA Display Drivers: Game Ready Driver 441.87 or Studio Driver 441.66 (slightly faster).
- Minimum Cinema R21 build is 115

Change Log: cntlc4d 0.590 alpha (2020 February 24)
[cntlc4d] Native C4D Node-based GUI for CentiLeo shaders and materials! Only for Cinema 4D R21.115+.

Known issues to be solved (temporarily broken features)
- Dirt shader;
- Absorption property of material;
- Directional/infinite light source;
- Adaptive noise-based image rendering (where pixels are no longer rendered when specified noise level is reached).
- May not initialize if AMD GPU is in your computer together with NVIDIA GPU.
- Very limited material converter tool (diffuse color + texture of C4D material).

Please, test it on you setup and share your renders!
Best regards,
Kirill

Hello Juan, the multi-layer output for exactly EXR is not yet there. Currently in area of AOVs we can output:
1) up to 8 light pass images (light groups) for changing lighting in post
2) and decomposition of beauty image into reflection, diffuse, transmission, sss and other passes.
This works but not yet a complete AOV solution. Will dive back into this area in a couple of soon to release versions. E.g. also would like to have Cryptomatte

Hi Aimar, I have updated the plugin. And also fixed denoising AOVs issue in R21. Check the Render Settings -> AOVs tab. It has 2 new checkboxes: "Denoise AOVs", "Keep raw and denoised AOVs". They enable/disable denoising for all CentiLeo output images. These settings doesn't affect Main Beauty image in case the central Cinema Denoise Effect is active (which supports only single Main Beauty image and process it by itself). Everything is based on Cinema / OIDN denoiser.

[cntlc4d] Added support for Cinema/OIDN denoiser in R21 for CentiLeo AOVs (see 2 new checkboxes in CentiLeo Render Settings -> AOVs: 1) “Denoise Images”, 2) “Keep raw and denoised AOVs”). If Cinema denoiser is not enabled with Denoiser Effect (which works only for Main Beauty) then CentiLeo settings enable this for it’s AOVs.

Hi Aimar! Pls, can you post example images with/withot denoiser and AOVs? Anyway there will be a dedicated release for AOVs and denoisers too!
As for Sun - I know. It's noted in the change log that it's broken in 0.58 (because it's the same as directional/infinite light), but will fix it at some time.

Hi Juan, thanks! The wheel is very nice, I like it a lot. However, there are duplicate polygons on that previously problematic area. Now things work well in this area. Currently I am working to fix another (more rare) crash bug which is still there

Change Log: cntlmax 0.584 alpha (2019 December 31)
[core] Fixed z-fighting render artifacts for coplanar polygons in the scene, precision is improved.
[core] Fixed few rare crash-bugs.
[cntlmax] Installation instructions are changed a bit, read them again!
