How to rig symmetrical deformers in #Live2D

STEPS 🍑✨
1. Make sure you're on the key where you rigged one side of the deformer.
2. Select rigged side of the deformer.
3. Copy Shape (Ctrl + Shift + C) then go back to default values/0 key.
4. Go to or make a temporary reflect parameter (-1,0,1 keys), key the deformer to this if you haven't yet.
5. Paste Shape (Ctrl + Shift + V) on either -1 or 1, just not at 0.
6. Reflect the motion/do Motion Mirroring. Go to the other key and Copy Shape.

8. Go to the key that you were originally rigging.
9. Select the unrigged side and Paste Shape.
