[QUESTION] How add decals to textures

Hello,

Thanks for developing this awesome tool.
I was wondering how to add decals to textures in BlenderProc. If there's no way to perform this, I'd like to request this feature.

What I want to achieve is to randomly place dirt or damage decals (also randomly generated) on a model texture to simulate imperfect objects. I'm aware of [MaterialUtility.infuse_texture method,](https://dlr-rm.github.io/BlenderProc/blenderproc.python.types.MaterialUtility.html#blenderproc.python.types.MaterialUtility.Material.infuse_texture) but this rather "blends" two textures together. I'm looking for a method that overlays one or multiple small textures over another texture.

I'd appreciate if you could share any insights on this topic. Thanks in advance!


Start with the MaterialUtility.infuse_texture method referenced in the issue and review how BlenderProc handles material and texture operations. Determine whether overlaying one or more decal textures is supported; done requires either a clear usage explanation or a scoped feature proposal for randomly placing generated decals.
