Actually, Pete is both right and wrong.
You can't use Acculips and iPhone live motion with a 3DX character, but you CAN apply saved motions you created with Acculips and iPhone Live motion on ANOTHER character to a 3DX one, as long as the 3DX one is mapped correctly.
For example, I have done this with the Daz cat, created an Acculips script as well as captured my iPhone face for emotions and saved the whole thing as an iMotionPlus file, which applied fine to the cat. So there IS a workaround.
(I don't think there's any way to uses Explus, though -- 3DX would have to allow us to be able to create the proper morphs for it. Although, now that I think about it, I DID use Explus on the character that I created the motions on. Hmmm, need to play some more with that).
