I'm rendering as movie (.avi) This because i've test that the network fails on the start, but if it don't fails on the first frame... it go to the end without problem. (I Hope... i'm rendering now!!!) Rendering image by image is a problem, because after this i need to add all images to a movie and after this i can compose the film... so in this way i've another step in the making of. (and i've short time) xman
