I never actually used bump_maps before. Now I try to use one, but not
seeing any effect. Can someone assist me?
The scene contains a stratosphere helium balloon, and the bump_map
should have created the typical balloon surface. However, I don't see
the surface changed. Before posting any images, I show you the scene
file. is there any error the way I do it?
