Coloring triangles/quads individually?

Hello everyone,

please forgive me if this is a silly question and/or answered in the tutorials - even though I did watch most of them, I could not find out how to do what I need to do.

I have a 3D object created with Alibre, exported as an STL, converted (via MeshLab) into an obj file and imported into zbrush. For the purposes of this question, let’s assume I’m talking about an open box - think of a hollow cube, cut off one side, and you’ve got a box you can put stuff into. This object consists, obviously, of a very small number of faces, vertices, triangles.

What I want to do is to make the outside walls blue, the inside bottom red, the inside walls green. In other words: I want to assign precise colours to precise triangles.

I’ve tried polypainting to no avail. How can I assign a color to a specific triangle/quad? I’ve been trying to use masking, but still couldn’t manage to assign a color to a specific primitive.

Any help would be greatly appreciated!

Thanks,
flyingcat

That will not work because polypaint is essentially vertex coloring - the points are colored not the polygons, so you get some interpolation across polygons. You need a dense mesh in order to get good results.

You will have to assign UVs and then create a texture map to get the result you want.
