Light bleeding through entire mesh on edges of corners or dependent on distance of camera to the mesh

Hey Everyone! I’m originally a environment artist but I have been using Unreal for a bit and still run into small issues like this. So as you can see in the video my directional light is bleeding through my mesh for some reason when I rotate the camera or move closer to the mesh. I have Tried everything and still cant figure it out. I did check my Light maps and everything seemed fine. Every piece is modular and have thickness with no holes in mesh. Normals have been checked as well. Also anyone know why certain parts of the mesh show up as “invisible” when looking at the surface cache view? Thank you in advance.



Ive Attached a video which shows the light bleeding issue. and a screenshot which shows my surface cache…for some reason some pieces are completely invisible
