Can I render single frames frome Video Post? When I try, it goes through the regular render cycle…"setting up lights", "setting up normals", etc. But when its finished rendering the frame it starts "setting up lights", etc. again. If I press ESC to stop the repetition, no picture is produced. I've also had problems with background images not rendering from VP that show up fine if rendered from the Keyframer. Any suggestions? Ian.
