Hi! Task: spread different geometry objects on “ground” plane at one time using 3D Paint Tool(Paint Scripts Tool) and color map("mask") assigned to “ground”. geometryPaint.mel script works well but it is useful to spread one kind of mesh only.
What kind of object must be paint depends on color sample “under brush”.(For example, green area on map is for spread grass geometry, yellow - for sand, etc.) How can I pickup such color sample on object with MEL?

p.s.: sorry for my English

You can bake the texture onto the verts of the geo. then loop over the verts?

rendering --> lighting/shading --> batch bake (mental ray)

That's good idea to use vertex color data. Thank you!:)
I found a command polyColorPerVertex.
One more problem - how to calculate face and check its vertexes color values. Geo is square divided with mesh grid just like chess board or map for turn-based strategy. Object must be placed at center (normal) point of face ("cell").
