Lighting Splotchy-ness

Everytime I try to build my lighting in Unreal, I get this splotchy effect on everything that I can’t seem to fix no matter what I try (adjusting lightmap resolution on objects, adjusting indirect lighting quality, etc.). Please help!

Welcome to the club. I have no idea what causes this, however, I do know two things about it.

  1. It only happens to some assets ( you might find it doesn’t happen if you change the wall material )

  2. It goes away when you package ( I know that’s not much help… )
