I'm also seeing the "reverse teleport" issue.

I've been looking into this too. That rbgschemes post above is great. But worth noting it doesn't work with the current unity integration... the principles are probably the same however. I've yet to get it working but will follow up more if I can

Thanks! Working pretty well in Unity 2019.2.2f1 so far

I've noticed this same thing with this sample scene in 1.40 EXTREMELY slow. It was actually crashing for me until I fiddled with some settings...
