    State of glTF 2.0 for WebVR Devs

Date: Sept 11, 2017.
Summary of the glTF 2.0 ecosystem, as it affects WebVR devs.
Engines


three.js, BabylonJS, and A-Frame v0.7.0+ support glTF2.0.
... and more.

Exporters and Converters


Blender glTF 2.0 exporter is quite good, I'd start there.
COLLADA2GLTF has a 2.0 branch that should be functional, but still beta-quality.
obj2gltf, works great from my tests so far.
... and more.

Key Issues


Exporting multiple animations per model isn't well-supported. Tracking issues
here and
here.
The Draco extension isn't quite ready for use yet, but looks very promising.
Currently all materials are PBR. If you need unlit for mobile performance,
there's another extension in progress.

Testing


When creating models, you can test them quickly in this drag-and-drop viewer.
Sketchfab has 100,000+ glTF models for download! They're great.
