Is there some way to set wanted moveable light in actor to disable after player gets far enough. So basically to be able to set culling for light? I am using loop in actor event graph to hide lightsource which is working good. But is there some cheaper way to do that?
You could use a trigger volume. When the player enters the volume it will turn on and when he/she leaves the volume turn off.
Trigger Volumes are fun… Hope that Helps =)
Triggers are fun but would it be cheaper? 
Will at least move the loop in project blueprint and toggle all wanted lamps from there. So would use only one loop, not have own for all actors.
