I have hundreds of animations/poses I've purchased for iClone 8/CC 4. I want to use these in Unity. How do I batch export all of these animations to a universal format like FBX? I don't see any options. 

Once you have all your animations saved as Motions or Motion Plus from iClone, go into Character Creator. -> File -> Export -> FBX -> Clothed Character.

Change preset to Unity 3D. Under the Include Motion tab, click Custom, then Open File. You should be able to drag in multiple animations.

The animations export with the character model when added to Unity.
