FBX2glTF VS OpenFBX

I've recently done this but not fbx only, was textures and some other asset files. Converted the model to gltf and then loaded it in for an augmented reality app. Just be cautious on load times. I had to compress it using this https://github.com/facebookincubator/FBX2glTF

i use maya to make blendshapes in FBX format then use https://github.com/facebookincubator/FBX2glTF to make the gltf and https://meshoptimizer.org/gltf/ to make the GLB

FBX can be converted to GLTF via this tool https://github.com/facebookincubator/FBX2glTF After convertation import GLTF as usual file

Using this tool (https://github.com/facebookincubator/FBX2glTF) FBX2glTF-linux-x64 on the POLYGON MINI characters I get this output

I found the https://github.com/facebookincubator/FBX2glTF project invaluable as a resource for seeing how to get useful information out of FBX.

I'm using the FBX2glTF found here and this is what I'm getting before the orientation fix;

I went with OpenFBX as it is quite lightweight (1 cpp + header for ofbx & miniz the only dependency).

My understanding is that it is proprietary, but a opensource project seems to be able to read it: https://github.com/nem0/OpenFBX
