ynsaen, "scale up..." I kinda see the logic of where you are going, and it comes back to my idea that there is a 'rounding' problem in the math somewhere..the rendering this high density complex situation at 30 fps is somehow exposing too-truncated math when the shadows are deep or something. I guess. Maybe "bigger numbers" after scale-up would relieve the pressure of something. Okay, I am going to keep experimenting. I might try a test at 20 or 24 fps, try the scale up, and also try some of the settings moochie suggests. I have to keep plugging, if there is no solution, I can't use Poser for this project, at least at this level of photorealism and high-pack animation. ::::: Opera :::::
