I am having trouble with normal maps. I get inverted normal maps on some of the polygons. Triple/double sided doesn't help.
Please help


Thank you.

Hi,

Are you sure that the polygon normals on those objects are consistent, pointing all inwards or outwards? Let me check the scene.

Thanks,

Well, at least in the cube scene it is hard to say if there is a problem with the normal map. I've replaced the environment for a light just behind the camera to see the normal map shading and it seems fine to me. Perhaps it is only an optical effect in your camera.

Thanks,
