textures not showing only normal maps

Hi, m using latest unreal version and dx12 RTX 2080ti, in the VR example of unreal studio, in the project I’m, using the HDRI plugin, textures outside the building are ok but inside there are no textures only normal maps, textures come when lights are placed but I need only global illumination scene and also path tracing is all black
