Here is the problem. When I render scene in the editor everything casts shadows as set ( all global). But in the keyframer only the first frame casts shadows, then they all dissapear. In any resolution. It is driving me NUTS! I have checked every light, every object. It is a very large scene. 120,000 faces, 124 objects, 15 lights. I have 32 meg on a P5 90. I get a report on the current status of 83000 page faults whatever that means. I have a deadline, please help! thanks Arturo
