Hi
iPi Mocap Studio includes motion transfer (retargeting) function. Thus you can import your character in any of the supported formats (including FBX) into Mocap Studio as target character, set bone mapping and export animation retargeted to your character.
http://docs.ipisoft.com/Animation_Export#Motion_TransferAnother option is to use retargeting functions of 3ds Max to apply animation of actor's model exported from Mocap Studio to your character. Consult with 3ds Max documentation/community to get more details.
