Hey guys, was curious if anybody knew of a way to affect the full scene roughness values through post-process? The idea would be to make it so that we can create full-scene effects like rain, snow, dirt and dust without actually having to add anything at all to the existing materials.
We can obviously read from the scene’s roughness, but there’s no way to write to that. We can affect the overall screen image, but we still have to visit every existing material if we want to achieve full screen effects that need to adjust individual channels.
I realize this is more of a feature request, but just think of the possibilities and I was kinda hopin…you know since we can read roughness? Maybe there’s a chance one day we can write it?
