Hello - I am trying to over-ride certain shader inputs (specifically base color and roughness) by overlapping one object over another in world space.
- Flat ground plane, base color white, roughness 1
- overlap a sphere, where the overlap happens, change base color to black, roughness to 0
I have been playing around with a number of different things but I can’t quite seem to figure it out, and the documentation doesn’t seem to mention anything like this. I feel like I need to end up with something like this:
However it feels overly complicated.
Does anyone have any ideas or could point me in the right direction for what I am trying to do? Would be very much appreciated, thanks!
