Okay before I say "Uncle" on this let me ask you one more question - but admittedly I am not so optimistic now. You said antimated lights were not present, therefore the shadows being generated should be the same through all frames according to how the lights/shadows are set in frame one. Go back into the Animation window and expand all the lights (click on the arrow thingie) and see if you have any key frames showing after frame one. If so try the same thing as you did with the shadowlit with the lights and clear all the frames but frame one and make that light constant. (If I understand your setup correctly this should not affect the lighting for the scene - only any changes to the lighting and shadow occuring after frame one) I have also had to do this before as well, but usually the fix to the shadowlite gets it. Also, I don't know that it would have made a difference but it might, normally after I apply the "fix" to the shadowlit (and/or lights) I save the file, close Poser, reboot my Computer, and start Poser clean. I do not know that this matters but I do know that I have had problems similar to this and these are the things I did to fix it - and they have worked for me. So I wish you the best of luck, and hope it might work for you this time as well. I'd say give it one more try. Do the shadowlits again (just to be safe) along with the lights this time, close down and reboot - and run another test avi and see what happens. Less that optimistic, :o( Rob
