So I retract my previous statement about blend4web not handling object instances – turns out I was just doing bad clojurescript 
Here’s another test showing object instances

That all said, I find this hard to work with and debug, and I’m beginning to think streaming 3d data might solve some of these problems.
Do you think armory would be able to stream 3d data in some way?
Thanks
