I'm trying to render an image which is abt 6 megs (I've been rendering much bigger files....) At a certain point everything stops, I hit Ctrl-Alt-Del and it says tha Bryce is blocked. I have no desktop image and no other programs running. Most of the mats are waters,only 2 "lenses" are glass but they are small. I also tried to render one small piece at the time, but it still keeps stopping. I have a Pentium II 233 Mhz with 64 meg ram. I had no problems before....How can I solve this problem?
