Hello
What software of khronos to convert to gltf format in maya exists or what 3rd party software you would recommend for this?
In general, Khronos publishes specifications like the definition of the glTF file format. Whether Autodesk (or any other company) decide to implement those standards in their own software is their own decision. I don’t believe there’s any official support, or indications of upcoming support, for Maya currently. Autodesk does support glTF in 3ds Max. Blender is a popular free tool with advanced glTF support, it may be helpful to you in converting from Maya exports (OBJ? FBX?) to glTF. Note that materials often need to be adjusted manually in these conversions.
