EDIT:Sorry, I realize I made no sense. Let me try again.
-----------------------------------------------------------------
I have created a wall and floor texture. I want the wall to be 3D. As of right now, it is just a flat wall and floor.
I have both milkshape and sketch up to work with. I have imported the flat wall into Milkshape.
-----------------------------------------------------------------------
I want to apply my texture to the mesh in Milkshape. Then, I want to mold the mesh with the texture still applied to align with the texture. Hope this makes sense.
