Hi, I already went through many messages re. problems with rendering. Nothing worked. I haveDell, Win 98, 1GB processor, with 20GB free space on C, and 512MB Ram. You can say that my puter is overqualified for Poser4, but here is my problem: basically I can render only small and simple stuff. I have to turn off "use bump maps" and "cast shadows", otherwise the program tells me that I'm out of memmory, or it freezes trying to render. Occasionally it corrupts my files. Does anybody have any new idea or solution to my problem?
