I am using photo view 360 to render an animation. It is a simple 360 degree rotation of an assembly, and after successfully rendering as an avi file, halfway through the rotation the animation goes black, and then after rotating to the side the black screen goes away. I thought this had something to do with shadows, so I chose a background of none and turned off the shadows. Not sure what to do now As this did not fix the problem. Any ideas would be greatly appreciated!
