I've been trying out some RTX GI in an environment i'm working on, for the most part it looks really good, but on some specific meshes (walls and roofs) they're being completely lit up, unlike the other side of the room which looks fine. Below in the images you can see the wall in the first one being lit completely different to the adjecent wall/roof. And in the second the roof is inaccurate. I have already tried different lightmap resolutions, adding thicker geometry to walls etc.
My lighting setup is just one directional light using RTX indirect lighting.
I was wondering if anyone knows what could be causing this?
Thanks in advance, I aoreciate any help with this
