Here > http://www.3dmoss.com/Fume%20Flicker.rar is my file demonstrating the problem. Its 3 clouds lit by 3 lights. Each cloud needs to be simmed to frame 8. If you then render a sequence from frame 8 you will notice the first frame rendered on a computer will not render the shadow on the middle cloud. Or you can render frame 8, then render the region of the middle cloud, and the shadow will appear. Maybe it is a memory management issue since the shadow appears when a smaller region is rendered?
