Hi
Currently, our software has keyframing capabilities for fingers only. For other body parts, you can manually edit the pose in each frame that cannot be tracked. There are tools like copy/paste the pose of selected bone and/or its children which make this process a bit easier.
When you encounter a "hidden limb" situation during tracking, I'd recommend you the following steps:
- skip to a frame where limb is back visible
- copy a pose from the last tracked frame
- adjust the pose if it has changed considerably
- hit "Refit Pose"
- continue tracking
After all tracking is done, get back to untracked frames and do manual editing. See also the "Cleanup" section in our wiki:
