I have a surface in an object that I want to be a light, one that can be turned on and off, not blinking, but more like a light switch. I have figured out how to drive the light, the emission value, using an another objects attribute as a driver. So if a Plain Axis X position is 0 the light is off, if it is 1 then the light is on. However this is cludgy, when I want to append the object with the light into another blend I have to remember to bring the Plain Axis object as well.
Is there a better or more tidy way of bringing a driver driven surface (or any driver driven thing) into another blender and bring the source driver with it? Even as a switch some where?
