Hello there! I don't know if any of you has ever encountered this problem but it has troubled me several times until now. I couldn't find any messages in the archive conserning it. Still I'm going to tell you the solution hoping that it helps at least someone since I've faced it so many times. I've discovered that images that have large black areas create flaws on the surface when used in the bumpchannel. As you you can see in the face of the clock is filled with black artefacts while it should be clear and white with only the numbers and the name of the creator raised and black. The problem was fixed by changing the value of the black in the image (to be used as a bumpmap) in Photoshop(or whatever you use) from 0 to 1 i.e. red, green and blue all to 1. -Hannu Kulju
