How to let light shine through static mesh from inside it

Hey guys, I have a lamp wich shines light 360* with an IES profile. The Mesh has some emissive fields going on so the point light needs to be inside the lamp mesh. The problem now is that the light does not come through the static mesh, the material is not two sided so actually should it be working. but it does not. Any help is appreciated! Thanks in advance :slight_smile:
ps: both sm and pl are placed in a blueprint (tested it outside: same result)
