Blender export to JSON not exporting animations, bones, or skinning

Description of the problem

Unable to export model with animation, no bones or skins are exported either.

JSON only contains:

"animations":[{
    "tracks":[],
    "fps":30,
    "name":"default"
}]

Export settings:

Three.js version

• Dev

Blender version

2.78

I might have some time tomorrow to throw something together (docs are definitely easier to update than UI for someone completely unfamiliar with your code base like myself).

But where is that menu?

Do you mean “Vertex Groups”? It’s in the “Object Data” Tab, see
