Lighting of multiple, small rooms

Hey hello,

I am hoping somebody can point me to the right documentation or tutorials for the following problem:

I am trying to light the inside of a boat - many small rooms with lots of stuff inside, so that about 5 lights per room are needed to get everything illuminated the way it is supposed to be.

I have to use UE 5.1.1, RectLightComponent and “movable”

It seems, that I can´t use too many of those types of lights before the UE starts to flicker.

My solution was, to create a sublevel for the lighting of every room and with it a streaming volume to trigger it, as soon as you step into it.

Seems to work, but the problem is the overlapping of the streaming volumes. They have to overlap quite a great deal, so that the lighting is already activated as you come nearer, so it doesn´t look as if somebody just turned a switch.

But with all the rooms cramped together a lot of lighting sublevels are activated at the same time, thus too many lights, thus flickering.

Any idea how to solve this more elegant? :slight_smile:
Thanks in advance for any help!
Cheers!!

You can set the distance the lights will work for, and how quickly they fade
