Hello,

I have a clean mesh but my directional light is bleeding through a solid mesh in Unreal Engine 5, How to fix it. and a small note I have imported this model from Sketchup with Datasmith.

Make an outer wall as if the walls had thickness, they don’t need to be well textured or anything if they’re not going to be visible, just something there to block the light
