Hi, I have a cube with a bumb map and the bump is showing nicely on the front of the cube but not showing at all on the side. I have 4 others cubes in my scene with differents texture and they all show correcly. This is not a scene I did but a scene a friend did at school that asked me to figure out why it was doing that and I couldn fighre it out. She was using an unwrap for a 6 faced cube with the exact texture on each sides and having all the faces over lapsing inside the unwrap. I taught this was the problem but wasnt. I woul like to post the file or a picture but I will only see her at noon. Hopefully I will have a answer by then by the little info I can give you all out here.

If anyone know the reason it could cause this plz let me know )

Sounds like it may have Planar UVW mapping on it, Box mapping is best suited for a box.
