I’ve modified Joshua Goldberg’s donut emitter so that a movie with alpha is texture mapped on multiple planes which works great. The problem is the alpha ordering I suspect: some video planes’s supposedly transparent part are masking other video planes non-transparent video part, but some are actually transparent as they should. To test you’ll need a video with alpha channel ex: quicktime animation… I’ve tried everything that had the word alpha in it, different blend modes, I’m not sure what to try next… Any pointers? Thanks.

Typically for transparency, you’ll want @depth_enable 0, or else the depth buffer will prevent seeing objects further from the camera drawn after objects closer to the camera with transparency.
