Mirror Vertex Group NAMES Instantly!

Easily mirror your vertex group names with this add-on—no need for manual renaming! It automatically swaps left and right suffixes so your vertex groups stay properly mirrored.

This is probably one of those tools that you never think you'll need until you encounter a situation where you actually do and you wish the repetivie task of renaming could be done with one click.

🔹 Automatically swaps left and right suffixes
🔹 Prevents name conflicts. No .001 duplicates! (Keeps existing groups intact while swapping sides.)
🔹 Supported suffixes: .L ↔ .R, .l ↔ .r, _L ↔ _R, _l ↔ _r
🔹 Preserves original case. Lowercase stays lowercase (.l ↔ .r, _l ↔ _r), uppercase stays uppercase (.L ↔ .R, _L ↔ _R).

Save time and keep your workflow smooth!

NOTE!
This will only swap your vertex group names based on their suffixes and doesn't create new ones. It only works with existing vertex groups.
