Hey,
I have noticed that when opening .glb in Aero the normal maps are always inverted, bumps become cavities. I am using Substance Painter to export the files.
However if I preview the .glb in the web viewer for example, the normal maps are rendered correctly.

Could someone tell what the specification is, should the normal maps be directX or openGL format? Khronos group article doesnt seem to mention it https://www.khronos.org/gltf/
I would really appreciate any advice you may have.
thanks,
Jaakko
