I hope that blender is far away from solutions like this. Last thing could be making any materials emissive and change ID´s. Not the one easy colored layer like in VRAY?! This way of work is not possible in the scene with 300 objects. If you export to EXR from blender and import with EXR_IO, you get lot of layers with alpha masks. I tried Cryptommate for object or material picking and exporting. I just need to get a perfect material Id Image. I also read this article How to achieve a flat colored render pass from material id/index for maskingĪnd for me It does not matter, If I have to use a python script. I tried to change the film Options - but it also destroys the render quality, so you have to render twice and the solution is still not antianalized, so it can´t be comparable with _output at all?! Exactly it was this article: Cryptomatte doesnt output nice clean edges I read another similar question in this forum and tried do my best. But the output in Blender-Cycles- Cryptomatte is very pixelized and not desired quality at all. After that, I want to import it in photoshop for postproduction. Blender people, please, does exist a solution to make a clean render pass for ID colors - materials? I want to achieve a same solution like in VRAY - material ID.
