Hello I don’t know if others run into this problem and stumble in here to find a solution, but here’s what I did to fix this when I ran into this problem:
On your light sources make sure that the Source Radius is half of the Attenuation Radius.
Example: My source radius was 1000 with a attenuation radius of 1000, but when I halved my source radius to 500 it immediately fixed the issue when hitting play.
I can’t figure out why this fixed it though ^^
