I just began learning Blender Python API, not sure if what I am asking is possible. I want to write a script to distribute objects on the surface of a mesh based on RGB value of a generated texture. Similar or identical to the way Blender already does it with particles emission. To do that, I assume I need to have a way to get RGB value at all the points on the faces of the mesh.

If that fails, what about just the vertices colors?

  • $\begingroup$ Not aware of a way to read the color value at a surface point directly (wish I did - if anyone does please lemme know! looking for this for a while). However you can bake from blender internal to vertex colors (not so in cycles as far as I know), and reading vertex colors in Python is fairly simple (if not entirely straightforward) as you can easily find here: blender.stackexchange.com/questions/909/… $\endgroup$ – TLousky Dec 13 '16 at 16:06
