Bitmap rotation error

[VASLAVO]

Hi guys, i just want to share about an error that i have on some images, if i had a bump map applied and i rotated lets say 90 degrees it appears to not work at all, as if there was no bum map but if i leave it at 0 degrees it work and everithing its ok, i thought it was because the bitmap applied was a tif but i change it to a jpg and it happens to, ill try to post an image about it.

images for reference

If you want to rotate a bitmap, only use the W parameter in the map's coordinates rollout, U and V won't give you the effect you want in that case. If it doesn't work, post a pic.
