Temechon Posted October 24, 2017 Share Posted October 24, 2017 Hello @lingkernyurk., It seems your OBJ file don't have the correct normals for the door. I downloaded your OBJ and opened it with 3DSMax, here is what I can see : See the dark red color ? It indicates the normals are flipped. It's the same for the other part of the door (you can compare with the lighter red on the house) : For me it doesn't look as a bug. One way to disable it Babylon side would be to set the corresponding material like this: scene.getMaterialByName('JoinedMaterial__3').backFaceCulling = false; GameMonetize 1 Quote Link to comment Share on other sites More sharing options...
