Hi folks, this is what I'm trying to accomplish: Making an asteroid space station with walls a different texture than the asteroid using boolean substraction.

I made my insides and corridor going outside using boolean union, that portion is a different texture than the base asteroid.  When I insert it into the asteroid and do my boolean substraction all my textures go default.  Is there a way the retain the different textures so that the walls, floor ceiling takes on the texture of the inserted part without attempting uv mapping?  I'm using Carrara 7 Pro.  Jan
