I remember some dot3 normal bumps looked somewhat inverted on the left-or right part of the model.Maybe its my idea only.
Also i remember i always had to invert the heightmap before converting it to dot3,otherwise rf rendered the whole dot3 normal bump inverted.
This guy says that many engines dont support mirrored UVW's,and describes three different cases.
RF supports any of these three?

Was the dot3 inverted because i had mirrored uvw's -or RF renders anyway dot3 normal bump inverted?
I will avoid to mirror or flip uvw's.
