I'm considering an implementation for an addon I'm messing with that adds lights to many hundreds of locations. The thing is, the VAST majority of the lights will be set to brightness = 0 until a distance proximity is reached. So, out of the many hundreds of lights, maybe one or two at a time will be lit, although it could be as many as ten or twenty I guess.
The question is: do lights with a brightness of 0 have the same performance impact as lights > 0? Are lights processed as lights regardless of brightness?
