I’m very new at unreal, I really like this this platform. So far I’ve solved all my problems with google, but I can’t get my head around this one.
I have a room with computers and I modelled some blinking LED-s on it (spheres with an emissive material that blinks on random moments). It worked very well until I added room lighting and then built the lighting. Now the room is lit well, but the LED-s have 0 light output. The lighting on the ceiling works (light bulbs with simple emissive material included).
Does it have something to do with that once you build the lighting, it can’t change in time?
