  • Add PhysicsControl plugin to the project
  • Add PhysicsControlGraph in CBP_SandboxCharacter
  • Enable/Disable physics control during :
  • On Traversal
  • While Pose != Default
  • While in ragdoll mode
  • Switch ragdoll system to use PhysicsControl
  • Add a toggle in Animation Editor Widget

Please, be extra nit-picky as it's my first UE5 PR 😅

Hey there, first of all this is pretty cool as mentionned before.
I am seeing an issue that we could maybe fix. Sometimes the arm can twist in the opposite direction of where it should go it we next to an obstacle like in the screenshot attached.
If we can find a solution to this, the rest looks pretty clean.

Also the ragdoll seems broken if we enter it with an OverlayPose active

- Ragdoll while OverlayPose active bug =>Remove IsPhysicsActivated check on ragdoll start/end
- "broken arms" interaction => Tweak upper arms/lower arms constraints (child rotation to -40)

Hello @PolygonHive!

Issues mentioned should be fixed! I didn't encounter any other bug, so I hope everything is good now 😁

As for the arm-twisting issue, this is what I've been able to get tweaking values in PA_UEFN_Mannequin :
