SkinnedMesh.clone doesn't work properly, results in undefined skeleton property

See original GitHub issue

When cloning SkinnedMesh, the resulting SkinnedMesh instance doesn’t have skeleton property defined.

I’m not sure if this is also a bug, but having a SkinnedMesh with undefined skeleton crashes the renderer with:

 Uncaught TypeError: Cannot read property 'frame' of undefined

https://github.com/mrdoob/three.js/blob/f177bce88ea3ff48818a30ff09d871133fcd245b/src/renderers/WebGLRenderer.js#L1343

Example

Three.js version

dev
r115

Browser

All of them

OS

All of them

Solution?

EDIT: (removed my horrible solution)

As mentioned, one is supposed to use SkeletonUtils.clone. I’d still expect some kind of warning about this, instead of the whole renderer crashing.

That’s a good point! Let me update the docs.

You have to use SkeletonUtils.clone() when cloning skinned meshes. Can you please give it a try?
