Getting it into your engine

Roblox
Upload albedo, normal, roughness and metallic, then set them as ColorMap, NormalMap, RoughnessMap and MetalnessMap on a SurfaceAppearance.
Blender
Albedo into Base Color. Set the other maps to Non-Color and run the normal through a Normal Map node.
Unity
The OpenGL normal works as it is.
Unreal
Flip the green channel of the normal map. Unreal expects DirectX.
