Bump maps - one side raised, the other lowered?
just watched a texturing tutorial from Digital Tutors. When he made the bump map, one side of his object had raised bumps, the other had indentations (he'd copied the bump for each side).
To get around this, he inverted one of the bump maps in photoshop, and this solved it. I've watched other tutorials on the same subject though and never seen this before, and in the little that I've done never came across it.
Anyone heard of this - could it be in an older version of maya?
