You're welcome... what goes around comes around :) System restore can only be done with XP, so unfortunately that's not an option as you're on Win 2000. I realise you're using the same render settings as you were before with the old .pz3s. But I was wondering if something in your system that's changed had affected either the P4 renderer or the Firefly renderer. Do you usually only use the P4 renderer? Can you try with Firefly and see what happens? Also could you try ticking "ignore shader trees" in the render options for P4 and see if that makes any difference? Also, if you turn off shadows in the render, will it render then? If it does, then it might indicate a problem with memory allocation? The final test would be to reinstall Poser 5. However if you then find it hasn't solved the problem, then okay, you've performed an important diagnostic step and now know the problem is with your system and not the program, but you've gone to all the hassle for nothing. Much better if you can solve it first! I recently did a reinstall as I was having problems with crashes. It didn't totally solve the problem, but it did improve it a little. (Still looking for the cause, which I now think is hardware related, probably memory.) So I guess sometimes Poser can just become unstable. But I took that opportunity to divide my content up into separate runtimes and reorganise it ruthlessly, so it was a good thing anyway :o) If you do reinstall, it's not such a huge job with P5, as you can back up your content libraries and then link to them from within the fresh P5 program.
