Is it possible to use the MOZ Lightmap GLTF Extension with vanilla threejs? #264

I'd like to use Lightmaps in Threejs exported from Blender, I know I could do this in Threejs with a separate texture but wondering if I could also just use the MOZ Lightmap GLTF Extension instead. Seems like it has solved a lot of issues with the Lightmaps being washed out, using the second UV channel, attaching the right Lightmap to the right mesh etc.

It is if you add the extension to the vanilla ThreeJS glTF loader. See here: https://github.com/mozilla/hubs/blob/bf6ed63453a8ac37bbabc3eb054aa05844b7d41e/src/components/gltf-model-plus.js#L635
