mountainmaster, Thanks for the link. I already knew about that thread. In fact, I posted in it. The problem there seems to be more with suspect MAT files than poser 5, although I'm not ruling out the possibility that there's a problem. At least half the people beta-testing for me will be doing it in poser 5, so I'm already taking precautions in that department. I'm reluctantly coming to the conclusion that I may just have to dumb down, even if it makes the pack more awkward to use. Ainle, I'm very suspicious of the Face library myself. I've had a couple of odd results with it and that put me off, at least, as far as anything for sale is concerned. mac
