Hey there.
This is somewhat hard to explain, but I´ll do my best.
I have a scene with many simulated flexible rubber balls falling into a glass fish tank-like container, and I want them to change color in the areas where they are in contact with the tank´s walls to simulate a cartoonish effect of them getting flat when they are pushed against the glass.
Can anyone please point me toward a node that can recognize that some of the geometry of one object is in contact with another object? I remember C4D´s standard shaders have an effect called Proximal that could do something like that.
Thank you.
