Lightmass Help - Photon Issues, maybe

been awhile, busy with stuff…but gotten back to this scene

@Makigirl

tried using portal - same results
bounces - no difference whether 10 or 20
lighting smoothness - lowered to 0.25
meshes are snapped, no overlapping faces
lightmap resolution - bumped up to 1024, same results
wall are obviously 3d meshes, else the light would just spill in from behind

what I found out is that directional light is the culprit for the light getting stuck in those corners.
just baking light with a skylight turns out fine, except for the overly dark “ao” at the corners.


Hope a dev can take a look into this regarding light bakes.
Although I know RTX is here with 4.22, but the GI implementation is still not ironed out atm so I’m using a combination (baked lighting for GI, RTRT for shadows)
