either that or is there a texture problem, do a single frame render, see if you have a problem, If not its the codec you are useing, there are many free ones out there that do a better job then stock poser ones. DIVX is one on them. I like to render my avi full frames uncompressed. then use an outside converter program to make them mpegs. It works alot better and you dont have to worry about haveing to rerender if the compressed version is messed up. Famine
