Hi,
We were about to use a bitmap as bumpmap in a project. The bitmap was supposed to be mapped in "screen" type, so that we could draw some cracks on surfaces directly on a preview render to have them on exactly these positions later on.
While if I take the map for example as a mask for a blendmaterial it works fine, but when I try to use it as BUmpmap, vray throws errors about invalid bumpnormals. When using the VRayColor2Bump the errors are gone but the map has no effect at all.
