If I have three shapes, is it possible for wherever they ‘overlap’ from the camera’s point of view, that the resulting shape is a different colour? Like this:
They’re not necessarily intersecting physically. My first thought was some sort of glass refraction…?
You’ll have to use compositing masks (cryptomatte) for this
If they are Grease Pencil layers i suppose you can mask them. I made an example, each shape has the other two as inverted masks and the white background uses all three shapes as mask.But in 3d i would not know how.
