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?

You can add a custom property to the light object, and refer to that in your driver. That way you don't have to depend on another object.

This will largely depend on how you set yourself up to re-use assets.

I personally like to put this kind of stuff in its own file, and create a group of everything needed. Save Save Save.

Then in my main working file I use Shift+F1 browse to my particular asset file. Double click on it. Then double click on groups. Then select my desired group name and pull it in.
