Hello Blender Community,
I have a scene where i want to generate a texture on mesh A by letting it interact with another mesh B. The goal is that i don't have to animate the texture by hand and everything is in real-time so i only have to keyframe Mesh B.
You can imagine it like when you're writing on paper: the part of the pen that touches the paper will turn it into another color.
In my case the Pen would be mesh B and the paper is mesh A.
Currently I can't think of any way to do that within Blender so i was hoping that somebody could recommend me an addon or a phython script.
Kind of like in the picture shown below:
