illustrator import without a background

hi. Anyone know the best format to import from illustrator into toonboom. I exported an object from tb (as pdf) into illustrator and dressed it up a bit. It seems I had to rasterize it to get rid of the background to get it back into tb. I’ve had trouble getting an eps file in tb also. Anyone know good settings to use from the illustrator export window? thanks. mm

from Toon Boom Studio to Illustrator, I export from TB to swf - import in Flash - export to .ai-format - open in Illustrator.
From Illustrator I save as .ai-file - then import in to TBS.

If you export from TBS to PDF - it will be rasterized.
