Well...there certainly were a lot of words and opinions in that string, but no real concensus on anything (from what I could make out) and Aleksander never got back to the string with any thing positive regarding the suggestions made. I have a great, fast, stable, roomy system and I should be able to render animation on it. I've never had any problems with Bryce 4. I have a number of intense programs (Bryce 4, After Effects 5.5, Premiere 6 w/Matrox RT2500, Flash MX, etc.) and there is no problem rendering animation or video on any of them. Any other thoughts, anyone? I really want this program to work because rendering animation is why I bought it. Besides this problem, it looks like a great program. Oh, BTW - my C drive is a bit low on space, but Vue 4 is not on my C drive and the drive I am rendering to is not my C drive.
