Field notes
The editor provides different manipulation rules for body parts: dragging hips moves a whole body, while grabbing a forearm or shin bends the corresponding joint. Users can pin a hand or foot, turn it into a grip near the other dummy, and switch collision settings to manage contact. The page also lists touch controls and starter scenes, including standing grip fighting and several named submissions.
