Hi,
uhn, yeah this one will require a custom camera control so that you make sure it stays consistent when you lok and unlock, if you are using the mouse to look at, during the lock, the mouse will move and so if you unlock, the camera will jump to the new location.
you need to experiement with the following:
get the "Get Mouse Delta Position:" custom action on the Ecosystem, and use that to rotate your camera around, then when you lokc/unlock, your camera will not jump, because it only check for the relative movement of your mouse and not it's absolute position.
Bye,
Jean
