Lighting Problem, static mesh from Blender

Hey there,

I created a small building in Blender and imported the .fbx into UE4. But now i have a problem with the lighting.
The light goes through the wall and i don’t know how to fix this:

(The point light is set to moveable, if i set it to stationary the light doesn’t go through the windows)
Would be nice if someone could help me with this.


hello looks like its not touching the floor. turn to side view to see if it touching and snapping to the floor piece. are those BSP blocks?
