Hello, I have a question about an animation I was attempting with POV-Ray.
In the animation, the pixels are seen to dance from frame to frame. It is
definitely NOT a problem with the video compression, becasue I scan scroll
through the individual bitmaps and see the same thing. I know POV-Ray says
NOT to use jitter or crand if you are doing animations. I was using a bump
normal to create a concrete texture, which I am beginning to think is the
problem - even though the documentation does not describe this as a random
texture. Is this likely to be the problem? Is there a better way to get
rough-looking textures without running into this problem?
