I was having a problem scanning out this sequence with the default scanline renderer where it would lock up the program in the middle of rendering a frame forcing me to skip the frame, so I decided to switch to Final Render which was working great until a little bit after the sequence started, where it began to “scramble” my textures on my object. Below is a sample. Does anyone know why this is happening?

Assign a matte material to it when you render the clouds, and check the ‘apply atmospherics at object depth’ option.
