Hmm I just opened the textures in Photoshop and it said 72dpi. Dunno about that. The real-time display of Poser (any version) won't work with texture maps 5000x5000. That doesnt affect the final render. The FireFly renderer itself, as far as I know, won't render any texture and bump that is 5000x5000; or so a friend tells me. I was told that the program is running out of memory, and that causes the crash. I am not sure if that person is right or not. P4 has different memory handling so that might account for the fact that it doesn't happen there. As far as why we went with the large texture size? I decided to UV map as map parts as possible in one section to get the fewest seams. And the resolution was chosen incase of close-ups and the possibility of poster print makers. Most renders don't need that kind of texture resolution, but its easier to go down in res than up, so we shot higher. My suggestion for anyone having problems is to reduce the image sizes by 20% or 4000x4000 and 1600x1600 respectively. I apologize that anyone's having problems, but neither Mab or I have Poser5 so we had no way of knowing about the problem, having assumed P5 would do everything p4 is capable of and more.
