movie file as an opacity map in maya08'
so yeh, the title pretty much sums it up,
basically my idea is to have a face appear in smoke and start speaking...
I would like to use a movie file of some sort to portray a moving image as an opacity map. but click the transperency tab>file> only lets you do .iff and other image files.
any ideas/ alternate approaches would be helpful
i hope i'm not being vague lol
