I've recently installed the Unity 4 Pro Beta (7) and am having problems retargetting MOCAP data to an avatar. My process is 1. Import avatar then configure it using the Mechanim avatar bone mapping screen. Works Fine 2. Import CMU MOCAP Walk fbx animation from the asset store Problems is that the MOCAP data does not have a simple avatar integrated with the animation data. Really why should it as its simply unimportant and wasteful. (The demo videos of Mechanim show simple avatars integrated with the fbx data). Can i have an answer from Unity team why this is neccessary? Seems no aparent reason why it should have. 3. WIthout this simple avatar i dont get the option to copy over to the avatar i imported thus i can't preview anything. When i run the game the animation walk does not get applied to the avatar. Can someone help me where i'm going wrong please?
