How do I export a scene from particleIllusion with an alpha channel for use in Flash?
Render out as a PNG sequence, and check the Save Alpha button. In Flash, go to File>Import and choose ‘Import to Stage’. Select the first image in your PNG sequence. A pop up will appear that says “This file appears to be part of a sequence of images. Do you want to import all of the images in the sequence?” Say yes, and the clip will load up on the stage.
