Babylon.js + glTF 2.0 Loader does not support skinning animation yet?

[cx20]

I tried the glTF 2.0 sample with some glTF 2.0 Loader.

https://github.com/cx20/gltf-test/tree/2.0#more-complex-models

However, Babylon.js does not seem to be able to display the skinning animation model of glTF 2.0.

Below is the error contents displayed on the console when loading the RiggedSimple.gltf model.

I think that the model of skinning animation of glTF 1.1 was able to be displayed, so it would be nice to be able to support glTF 2.0 display as well 

Thanks.

It should be good today or tomorrow We have it ready!

 @Deltakosh Thank you for supporting skinning animation!

I confirmed that it works except models of WalkingLady and BrainStem.

See : https://github.com/cx20/gltf-test/tree/2.0#more-complex-models

WalkingLady does not display even currectly with other glTF loaders, there is a possibility of a problem with the model (or converter).

I think that BrainStem is WIP because "Not implemented" error is given.

@cx20 Thanks for the report. I'm working on the "Not Implemented" error.

https://github.com/BabylonJS/Babylon.js/pull/2379

That should fix it.

[cx20]

@bghgary Thank you for fixing. I will try it when Nightly build version is made.

I confirmed that the BrainStem model is displayed with the glTF 2.0 loader of Babylon.js. It looks good
