Hello everyone!

Finally we are releasing the 0.58 update of CentiLeo for Cinema 4D R16-R21. It was a very complex development with a lot of changes and novel methods. We have got 2x - 10x rendering speedup. The render speed is always at least 2x better than before and depending on the lighting complexity the speedup is even higher. See below!
Some polishing and issue fixing still should be done but results are already very cool!

Change Log: cntlc4d 0.585 alpha (2020 January 27)
[core] 5-10% rendering speedup
[core] Fixed shadow catcher weights in case of many light sources (makes shadows of different intensity per light source on the Matte/Shadow Catcher object).
[core] Fixed shadow artifacts in case of very small area lights.
[core] Bitmap file paths now support Unicode strings (not just English).
[core] Fixed camera Auto Focus in IPR ([AF] button).
[core] CentiLeo updated to CUDA 10.2.
[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.
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 0.584 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.
[cntlc4d] Cinema R21 support.
[cntlc4d] Installation instructions are changed a bit, read them again!

Change Log: cntlc4d 0.581 alpha (2019 November 21)
[core] Fixed bug with multiple lights sampling. Now scenes with many lights have much lower noise than 0.580.
[core] Fixed rendering artifacts in case of rendering out-of-core geometry with near/far clipped camera.
[core] Fixed a couple of other minor issues/artifacts.

Change Log: cntlc4d 0.580 alpha (2019 September 23)
[core] Rendering speedup from 2x to up to 10x:
- Render iterations are around 2x faster almost always (base speedup);
- Render iterations become smarter and reduce the noise better for global illumination, in some cases it is required 2-4x less iterations to get same noise level as before. These improvements are best visible for interiors and night scenes especially for regions with dominated global illumination and lack of direct lighting. This improvement work for all area lights, mesh lights and environment HDRI with portals.
- Mesh lights with complex shapes (more than few polygons) generate 3-4x less noise than before.
- The new algorithm should be always better and more robust than the previous one (less noise per iteration and faster iteration time).
- And there is no cache, no blur, no yet denoiser, no aditional settings, no additional memory consumption 8)

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

Some comparisons.
First one: grey interior, 1920 x 1080, HDRI + portals and spot lights inside. 4 iterations (256 samples per pixel).
Noise in dark GI regions is reducing at much faster rate than before, and it is more uniform across the image.

Another test with interior. Indirectly lit area has noticeably less noise for the same number of render iterations. And iterations are 2x faster. However the spot light spread angle looks different due to changed falloff function.

Test for mesh lights. There are around 70 cylinders with emissive parts. 2x faster iterations and 10x less noise
 
Awesome :D .. the pictures look very promising ..unfortunately i am not very familiar with Cinema4D :cry: .. gonna have to wait for the 3dmax version ;)

Hi, I am doing the plug for Max currently on the side of plugin code. Pushing hard to finish it early even with few bugs :)
 
hi Kirgman,
did you do something with rounded edges/corner feature?
thanks

Hi xxx, no yet, there is no yet round edges support yet. Will do this feature of course, but currently have priority to make R21+nodes, massive particles and AOVs.
Have you tested the last 0.58 version?
 
not yet but I will this weekend, I ws already impressed with the former release I've just tried on some renders but fore sure with round edges I could start to think this would be my major rendering software, for cad users it is a lifesaver feature, please do something about it ;)

I know I know about how important is it :) Thanks for promoting this feature!
 
Does it work with R21? I've almost switched completely to R21 now. Also Is it going to work with teamrender or some other networking solution? Thanx!

Hi Konstantinos, currently I am working on R21 and want to provide support of it's nodes. As for teamrender - currently not yet, it's in TODO list.
 
Hi Kiril! all the Centileo Tags are broken in R20.
 
also render to Picture viewer seems not working because when you change to Centileo in Render preferences the tabs are empty.

Hi Rodrigo, thanks for bugreport! Do you find any files in the Cinema 4D R20/plugins/CentiLeo/res/description folder? There should be cntl_tag_envmap.h, cntl_tag_envmap.res, cntl_tag_light.h, cntl_tag_light.res and etc. Basically .h and .res files for shaders, materials, tags and render setttings. Also there should be Cinema 4D R20/plugins/CentiLeo/res/strings_us/description folder containing .str files for shaders, tags and so on.
If you don't find such files in these folders, then try again copying them from downloaded CentiLeo RAR-archive. They are all in the folder CNTLC4D 0.580/C4D R20/plugins/CentiLeo which has CentiLeo.xdl and res/ subfolder. I have found some extra not needed files there from my tests. But all needed is there.
Also what language do you use in Cinema GUI? Non-English? However should work anyway.

Rodrigo Bitencourt Rodrigues, please test again, I have reaploaded the archive removing non needed resource test files (some even had some Russian symbols in the names). Tested in R20 - it was ok, all tags and render settings are in place.

in R21 intel denoiser work perfect :) Except AOVs .
but sun doesn't work

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.
