GLTF PBR Material Anisotropic

Hello, and thanks for any help you might lend. I have been walking the export path between materials in Maya and Babylon and noticed that none of the GLTF extensions are passing anisotropic parameters from the file to the loaded scene. The exporter is using the ‘EXT_materials_pbr_specular’ extension, which has been deprecated or removed, and without it none of the other extensions include parameters which could host the value. The same extension was responsible for passing reflectivity and reflective color.

Is there an available extension which I can pin anisotropic values to or plans to add one?


Anisotropy is not yet supported by gltf/glb files, but an extension is in preparation:
