hi, i made an emissive map in my material and masked out the emissive areas by an ID map. (material is used in UE4)
when double checking the masks by copying them into a new file and use levels, i can see that they are 100% clean.
however, when i export the flats and double check the emissive by leveling it to high contrast i can see artifacts.
for any other map this wouldn't matter so much since the artifacts are barely visible, but the emissive will be multiplied in the shader by a very high value and then the low value pixels will also be visible very much.
question: how would i properly mask out the emissive areas, without having to process the emissive again after the flats export?

Have you tried lowering the opacity of the other masks, that might be the culprit!
