The biggest part of the new things in Poser 5 seems to be the materials system. The only time I needed anything like that was an army camouflage texture for my man in boilersuit (in a Sea Patrol scene), and I did that thus: In Bryce look straight down, texture the ground plane, render, save, use the result as a Poser 4 color texture map. Also, thank God that I had already copied my Poser 4 and Bryce 4 serial numbers onto another piece of paper, as I could not find the original boxes with them on, but I found that copy. (I have now copied them on again onto another piece of paper.) Of the people who ask for serial numbers, I suspect that some are genuine and not warez'ing.
