In Moon Animator, Ctrl + R is commonly used to reflect or flip the rig/animation , basically mirroring the pose to the other side. That’s the keybind people usually mean when they ask about Ctrl + R in Roblox Moon Animator.

How to use it

  1. Select the rig or the keyframes you want to mirror.
  2. Press Ctrl + R.
  3. Check the opposite side of the rig to confirm the pose was reflected correctly.

What it does

  • It mirrors the animation from one side of the rig to the other.
  • This is useful for symmetrical poses like walking, punching, or waving.
  • It can save time when you only animate one arm or leg and want the other side to match.
