Hi...
Unfortunately ActorCore characters are not compatible with Character Creator 3 but will be in Character Creator 4.
If you want to export multiple motions then the best way to do it is to use 3DXchange. To do this just send the ActorCore character to 3DXchange, import the motions you want exported with the character, and then add them to the Perform list in 3DXchange. Then you can export the character along with all the motions to FBX.
