Material with No Albedo, Only COMP and NORMAL?

[LHSimulations]

I think vertex color could be used like that. You leave the albedo empty and apply some kind of vertex color and use composite and normal.

I think in this topic they talk about this exactly:

Using vertex color for projected meshes

I am making a large projected mesh for my EKCH Copenhagen Airport package and I texture and map everything in 3ds. I try to limit the number of textures for performance reasons, and it seems that using vertex color is a good way to create color variation and at the same time keep the number of textures down. The screenshot shows a test projected mesh with four asphalt color shades using vertex color, only one asphalt texture. In relation to performance, is extensive use of vertex color for large…
