Rendering speed needs to be improved
Administrator Posts:
ssjenforcer, it works progressively. The user first opens the IPR and see how the noise goes, then adjust the max iteration count to the number that gives better speed for desired noise based on few experiments on a given scene with a given lighting.
Default 32 iterations is an example, of course very often a smaller number of iterations is enough. When I will recover the feature of adaptive rendering based on per pixel noise then these 32 iterations will finish very quickly if for example 8 iterations are already enough. It will look much faster for the scenes where the most part of image has much less noise that the other part.

Shadow catch pass (multi-pass) does not work under any settings, shadow catch never shows up, and I have tried many combinations of settings
Administrator Posts:
In case you use node material editor there is an Emission material node that can be used to plug into Output node or it can be combined with Material using MixMaterial.
Otherwise you can use simple not-node based materials, this way an Emission channel is available inside the Standard CentiLeo Material together with Reflection, Diffuse, Alpha and other channels.

1) Sky + HDRI using CentiLeo environment tag, it has shadow weight. 2) Directional (Infinite) regular light with CentiLeo light tag, it has has shadow weight. 3) Regular light of Omni type with CentiLeo light tag, it has has shadow weight. Other types of light sources (area, spot) don't produce shadows on the shadow catcher plane. If you want to exclude some lights from producing the shadows then just make shadow weight equal to zero. Or make it a smaller number to make this shadow weaker compared to others. This feature is nice itself and has potential to future improvement.

Animated image sequence or video file mapped to material? Is this possible or coming later?
Administrator Posts:
This video file sequence will be supported in the future. At this moment only static images are supported as bitmap.

That remaining shadow in front of the tree is probably casted using the light source that is not switched off. The bottom line status bar says there are 8 light sources in the scene.
How did you implemented the colored light sources on the tree? 1) If they are regular cinema omni lights with centileo light tags then by default they will cast shadows on the shadow catcher. In this case you can set shadow catcher matte weight to zero for all such lights. 2) If you have implemented the colored light sources on the tree with the spheres and emission material then they will not produce the shadows for the shadow catcher object and will not affect it. This is a preffered way for render speed for this scene if you don't enable imprortance sampling for such emission materials because their lighting is local. If you want the shadow catcher object to receive the shadow only from the one light source or Sky HDRI then only this object (using CentiLeo light tag or environment tag) should have shadow catcher / matte weight equal to 1. And all other unwanted light sources should have shadow catcher / matte weight equal to zero.

Русский язык, Перевод centileo

Hi Vlad! Welcome to CentiLeo! Here we prefer speaking English. Thank you for the question! In the future we will certainly translate CentiLeo to Russian language, the challenging part will be to translate the documentation, there will be lot's of work.

Why does IPR lighting never look the same as final render? (too dark in render)
Administrator Posts:
Enable Transmission channel for glass, it has IOR for refraction. Alpha channel has no refraction IOR and has no roughness.

Have a look at this post:
And this In short, there can be Filter settings in PV turned on/off. There can be "Send raw AOVs to Picture Viewer" enabled in AOVs tab of CentiLeo render settings. Just check these options

IPR renders fine but Render to Picture Viewer generates black images?
Administrator Posts:
Do you animate the brightness? How many light sources are there in the scene? Btw, it's not easy to detect the issue without the scene itself.

Can it convert assets into centileo shaders in batch?
Administrator Posts:
Hi Ivan.Huang, and welcome here! I know automatic material converter is surely very much needed for us. We will start working on it soon, I hope it will be released in 0.67 release and it will include standard C4D materials, Octane and Redshift to convert from.

You may test what settings really work for example by testing the animation in lowres just to get quick renders, then apply denoiser. Denoisers behave this way on extreme low sample counts.

It looks like you use denoiser and low sample (iterations) count. That's why it flickers. CentiLeo doesn't use biased techniques inside.

Actually only experiments will help to find the right settings here. On CentiLeo side we will implement a lot of AOVs (extra images), mask images, some funtionality to combine them in the output. It's all possible because we have a very good architecture to support the render and output of really many images at once.

Thank you very much for this free Plugin

Hi S1512, thank you very much for kind word! Welcome here! We work with great enthusiasm! A lot of very important features are on the roadmap. Volumetrics are there too, but they will appear later than other important things

It looks like you are doing a very good AI progress! Actually I can't believe such cools things are coming to life! Hope to test them at some point.
Blender is a good path, but I would also recommend not to forget Cinema 4D, first of all because it's also very cool and progresses nicelly, and also because CentiLeo is there
Looking forward to see you animations!

Glad, you fixed this! Btw there are also options in C4D file saving something like "Straight Alpha", "Pre-multiplied Alpha".
Also in CentiLeo render options (in AOVs tab) there is "Transparent Background" option that also kills the reflection of background on reflections as far as I remember
