There is another similar thread on this topic: [Support Other Textures in GLTFLoader](https://forum.babylonjs.com/t/support-other-textures-in-gltfloader/7293).

The official way to support Basis Universal in glTF is to use KTX2. See here: [https://github.com/KhronosGroup/glTF/pull/1612](https://github.com/KhronosGroup/glTF/pull/1612)

I am already working on the implementations for Babylon, but they will take some time to finish as there are issues with the KTX2 libraries at the moment.
