Can the Light Rigs be controlled without using LightRigger?
To a limited extent, yes. LightRigger is based on the use of instanced controllers to keep the different components of the system working together. This means that the LightRigger system stays intact and synchronized whether LightRigger is open, closed or not even installed. This also allows someone without LightRigger to change many properties by opening the Rigs, selecting individual lights and changing the instanced controller values directly.
