I'm working on a project and I've run into this annoying lighting issue with one of my walls:
This one wall is brighter than the others and it has this glow around the edges and around any intersecting assets like the door and painting.
The walls for the building are all one mesh (not the best choice I know) and there's a room the other side of the wall.
The lightmap and normals are fine, no different from any of the other walls that have no issues.
The walls intersect with the floor and ceiling well too so no light is bleeding in that way
The room behind the wall is pretty bright and I wondered if this was the issue.
I tried blocking off the light by placing a cube in the wall, but no effect.
Then tried turning the indirect lighting from my directional down from 6 to 1 and the issue became less noticeable but was still visible (and ruined my lighting too).
Tried changing the wall mesh to moveable and this fixed it but obviously that's not ideal for static walls (also messed up my lighting and the walls don't show up in my reflection captures).
Wondering if anyone has and other ideas on how I can fix this?
