FBX2glTF VS glTFast

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;

May i recommend GLTFast instead considering it is more recent? (last updated in March) https://github.com/atteneder/glTFast

Another discovery. GLTFast seems to respect this instancing: https://github.com/atteneder/glTFast

I would recommend looking at https://github.com/atteneder/glTFast personally. There are some scripts for having your own custom material such as ones from shader graph, URP, or HDRP. I have used glTFast before without any issues, but haven't tried to change the default material.

glTFast offers superior performance and more features.

glTFast offers superior performance and more features as well as experimental support for export.

Convert byte[] to GameObjects with Meshes and Texture2D using a plugin (https://github.com/atteneder/glTFast).

Do you mean the zip here? https://github.com/atteneder/glTFast/releases/tag/v4.6.0 ?
