Hello everyone.
I have set the useMicroSurfaceFromReflectivityMapAlpha to false, and then export the scene to glTF files got the error:
_ConvertPBRMaterial: Glossiness values not included in the reflectivity texture are currently not supported
Is there any solution to make the glTF expertable.

The exporter doesn’t support this combination (having reflectivityTexture with useMicrosurfaceFromReflectivityMapAlpha false). Using specular/glossiness workflow will also be lossy conversion to metal/roughness. It’s better if you can start as metal/roughness workflow if you want to export cleanly.
