[Question] What are the behavior differences for physics constraints between PhysX and Chaos and what issues are still to be fixed.

For example I’ve observed that setting linear limits on X and Y at the same time does not yield a circle area, but a square one. Why was this changed from the PhysX behavior? And how to generate a round one?

Also, what’s up with the soft constraints? I cannot seem to make a simple spring. Can you please show how to do a bouncy spring?
Edit: even in 5.1 soft constraints don’t seem to be working.
