Hey Brian
I did it just now, and create caps is selected on default, but once I add some extrude, the back texture goes completely out of whack, as in, it is multiplied 50 times on the backside of my extruded polygon plane. Once I hit a negative extrusion number, making the extrusion go the other way, the front texture is multiplied. Do you know how I can add the depth, and have both front and back textures appearing normal again?
