Summary
Neither Spring Controller nor Anim Dynamics seems to work on end bones any more (5.8.1). Tested using Metahuman. Removed _dyn bones to see if this fixed, but nope.
What Type of Bug are you experiencing?
Animation
Steps to Reproduce
In MH Anim BP, AnimGraph, add in either a spring controller or a Anim Dynamics node. Set for bone thigh_bck_r (an end bone) for example. Give exaggerated values in the nodes. No effect on compile or runtime. Change bone to thigh_correctiveRoot_r (not an end bone) without changing other values, and it now works. Whatever end bone selected, no effect is apparent in sim or runtime. This is either translation (linear) or rotation (angular).
Expected Result
Expect similar results when using end bones with the nodes, as non-end bones.
Observed Result
Spring controller or Anim Dynamics gives no effect on end bones, but both work with non-end bones.
