[Light/Shadow] Light shining through static meshes

[]Innuendo[]

Hello,

I have built a Static Mesh from BSP (for prototyping), it's a simple wall. Then I have built a closed room with it. When I light it with Dominant Directionnal Light, I see inside that some light shines through :
- Can it cause damages to my level ?
- If yes, how can I do ?

Thanks

All the Static Mesh and Light and Lightmass properties seems to be OK (cast shadows is checked...),
Do I have to create one streaming level with Dominant directionnal Light for outdoors and one without directionnal light for the inside (romms...) ?

Hey buddy, does it have back faces is it a closed off object? Maybe upload some screenshots you'll get better help and more people will be willing to look into your problem.

Thanks
Joe

ok, ok, it's a closed room without light. The directionnal light comes from right :

I solved the problem by adding a lightmap UV to my mesh..
