This is an interesting post, but I have a serious problem with it - I can't really confirm it. Above you see four pictures, left to right. From left to right, number 2 is the Poser4 bumpmap conversion of number 1, and number 4 from number 3. If you look closely, then number 1 (the black circle on white background) is *not* converted as reported above, while number 4 is actually the "repaired" version. It looks like that (at least) my version of Poser converts them very different to gillan's copy, and - to my knowledge - the appearance of my samples is indeed the correct conversion. Could this be a PC-only problem that doesn't show on Mac?
