I began using Bryce 5 recently - and had what I thought was a decent animation idea. I set up all the parameters and began the animation rendering process. The animation was calculated (by myself) to render for about 6 hours - too many glass transparent textures and light sources possibly. I run this software on a virtually new PC with windows XP. Somehow, when I return to examine the progress - the program (or something else) has seized up and could not finish the rendering job. I killed the screen saver, in advance of this job - but still without success. Any one out there have any helpful hints? Be merciful - for I am but a beginner in this realm. For your consideration - I thank you.
