Yeah, sorry for diverting the topic a bit... :-) I believe that it is a sort of bug which the PC Poser seems to suffer from, all that I can say is that it doesn't show on my testing config. To clear things up a bit: Texture references are indeed handled very differently on PC and Mac (Poser even uses a different method to store the references inside a file), so this could explain why it works on Mac but not on PC, but in this case it doesn't really. The emulation I was talking about is a 100% (well, 99.99% :-) simulation of the PC hardware, with an original unmodified bona fide vanilla Windows running - if you install it from the Microsoft CD it even identifies the environment as a real PC hardware. I have a clean W95 installed, and I have a clean US Poser 4.0 (unpatched, I never bothered to get the PC patches because I don't really work with it, of course), and all I can say is this: On this config, the texture "substitution" does work, so your bad experiences are neither fate nore a basic disability of Poser, but something affected by other odds on your computer - otherwise I would experience the same behaviour when I try it out.
