[UE 5.7.2] Valley of the Ancient – Enemy never recovers from ragdoll (confirmed not working)

I want to confirm that this is not working in UE 5.7.2.

After further testing:

  • The project loads correctly
  • Assets and actors register normally
  • No crashes or runtime errors
  • Gameplay continues

However, in UE 5.7.2:

  • Enemy characters enter ragdoll correctly
  • But never recover / never play get-up animations
  • They remain permanently in a ragdoll (lying) state

The same project works as expected in UE 5.3.

This appears to be caused by changes in how UE 5.6–5.7 handle:

  • Ragdoll → animation recovery
  • Physics state cleanup
  • CharacterMovement / AnimBP state transitions

At this point, it seems that Valley of the Ancient (an older UE5 sample) no longer functions correctly in UE 5.7.2 without manual modifications.

I would appreciate clarification on:

  • Whether this behavior change is intentional
  • If there is a recommended recovery pattern for ragdoll characters in UE 5.7+
  • Or if this sample is officially considered unsupported in newer versions

Thank you.

Yes the giant machine ancient one stands up in the cutscene then instantly snaps back to start pose lol. Engine change broke the sample’s custom StateMachine?
