I have been wondering for a long time, if there is an easy way to convert Trapcodes 3d strokes, created in AE, to vectors for use in Flash. I need to use the strokes for masking other objects in Flash, so it´s not enough to just import them as a swf or flv with an alpha channel.
Right now I am exporting my 3d stroke-animation from AE as an image sequence, importing each frame into Illustrator where I live-trace them to vector objects. Then I must paste and position each object on the stage (and timeline) in Flash, rebuilding the animation, and then finally using this animation as a mask. A very time consuming and tedious proces :(
