The uv-mapped wall would be a simple, box-like geometry. Bricks and 
plaster would consist of two different textures, bricks with an 
image_map and plaster as a pigment pattern. In a more complex way, both 
could be made of two different geometries of course (more naturalistic).

I was thinking of dirt as identical for bricks and plaster. I shall have 
to experiment with your suggestions.

Thanks Jaime! Some thoughts for experiment and thoughts.
