Remarks

Whether the light can affect the world, or whether it is disabled. A disabled light will not contribute to the scene in any way. This setting cannot be changed at runtime and unbuilds lighting when changed. Setting this to false has the same effect as deleting the light, so it is useful for non-destructive experiments.
