How do I lock the root skeleton to test the physics

HI!! @OVERHORN13 What you’re seeing (the whole mesh falling to the ground) happens because the root bone is not properly locked during simulation.

To fix it, you need to set the root bone’s physics body to Kinematic inside the Physics Asset Editor.

Steps:

  • Open your Physics Asset.
  • In the hierarchy (Skeleton Tree), select your root bone’s body (in your case, farmer00).
  • In the Details panel, set Physics Type to Kinematic.
  • Once set, you’ll see a lock icon appear next to the bone — meaning it’s now locked and won’t simulate physics forces like gravity.
  • Now when you simulate, your character will stay in place, and only the ponytail will move freely!

If you’re still facing challenges or have new questions, feel free to share.
