Is there a way to get a mask rendered for decals?
For instance, in the attached image is there a way to render a mask for the pink parts which are a Corona Decal in this case?
Material ID, Object ID, or anything else dont seem to work.
Previously in situations like these, I would have to make a second render with a black material override for all the materials in a scene, and then turn all the label/decal materials into self-illuminating materials to get a black and white render to use as a mask in post. I was under the impression that Corona Decals would spare me the second render.
