bsp and imported msh same lightbleed

Hi!

New information, i found out that the the roof part facing the light looks allright, but the rest of the parts of the room that does not, have this weird lightbleed.

In the image, the roofpart, is a bsp, it shows the lightbleed thats the same as on the imported geometry theres no diffrence between them.

Problem(s):

Theres two issues, one it looks like the interior_wall is not intersecting with the roof, even though it does. And then theres the weird light bleeding

what i tried with the Lightbleeding:
Upping the res on lightmaps, shadows are great, but not the part in the picture.
separated the uvshells for the Roof, layed em out with a LOT of space inbetween.
used a plane
used a bsp

Fiddled around inside postprocess volume, but there wasent anything there that helped me.

I hope and look forward to the kind soul thats willing to shed some “light” on this subject!

Have a nice day.
