Unreal Engine Livestream - Animation & Physics Updates in 4.17 - August 31 - Live from Epic HQ

The point is to animate the curve, and use it in animation system - using pose node or pose blend node in that link.

We don’t support spring curve though as overgrowth, so that will be issue, but other than that, you use it like normal animation, except you’ll have pose blender at the end. We’d like to make a test project for this, but not yet. Good luck.
