Hi...
To be able to use iClone's animation tools requires you have a Standard character (such as CC3+) or a Humanoid (Non-Standard) character. If you just drag in a rigged character that isn't either Standard or Non-Standard then the only animation options you will have is keyframe animation.
So to resolve the problem you need to convert the character to Humanoid (Non-Standard) in Character Creator 4 or re-rig it using
AccuRig. If you do this you will then be able to use the animation tools in iClone.
If you need help with the workflow in CC4 then please see the tutorial below.
