Question, why has the development halted in this repo?
Is it unmaintained or is there simply no reason for updates?
really good question
In case you are still looking for more active projects for GLTF integration in Unity, these two seem quite interesting: glTFast and GLTFUtility
There's also an active fork, https://github.com/prefrontalcortex/UnityGLTF, which will be PR'd into this repository here at some point to at least bring it back into shape and make sure other people benefit from the fixes we did.
Update: PR has now been made. If you care about this repo it would be great if you check that –
- https://github.com/KhronosGroup/UnityGLTF/pull/644
Thanks!
