Overall this looks great. I added a few nitpick comments. Your teapot example loads perfectly and I verified that three.js does the right thing: there's just one single geometry, referenced by five nodes.
I was hoping this would also fix a model I have, that uses instancing... but no such luck. Not sure what's going on there. I'll write more about it in the issue.

Maybe we should make this available in a common header file...

Can you fix up the indentation here (and anywhere else)?

Let's not leave commented-out code -- just nuke the line.

Great! Thanks |
I've changed the code to allow several node shares the same mesh.
Here you can find a test to test that feature:
https://drive.google.com/open?id=1CKbDGCX2wSo8VpP07vwLsEjuEZxftc3K
It produces only 1 mesh, and 5 nodes that uses the same mesh.
Best regards,
