I'm using VR mode to make poses, but it's always a problem with posession. When i turn on poession (or using embodiment plugin), set a pose, i have to break right hand and head pose in order to chose "stop posession" button.
Use the keybindings plugin to set a keyboard keybind to deactivate Embody for example. Or set some timer with logicbricks to deactivate Embody once triggered, I don't know, be creative.
