Good Morning Jim . . . 8^) I had a similar problem when trying to apply a bitmap to a terrain. When I attempted to apply the bitmap to a terrain, I would get a patterned surface on the terrain, where it should have been smooth, because the bitmap was one solid color in these areas. I sent e-on a message & all the files for this problem, but haven't had any replies, in two weeks now, so I don't know what's going on over there? Have a good one . . . Mark. ;^)
