Hello guys, it seems that in my bumpmap there is a weird line. First I thought it was the camera, but even though consulting my manual and 'Advanced Maya Texturing and Lighting', I think it could be the bump map. I doublechecked the bumpmap itself, but to no avail.

I included the url to the full rendered image. There is a little line running though the 8 for 1, it makes a 30 degree turn at the 1 and I can't find the cause of this line.
