Why can't Maya mirror these joints?

[kathal-2]

Hey! I'm attempting to mirror a skeleton that I created in Maya. The joints are prefixed with "R", like this:

I set the "Mirror Joint Options" dialogue box to search for "R" and replace it with "L".

However, I get:

// Error: Too many arguments. Expected 1, found 0.

Which is odd, aren't "R" and "L" my arguments? I've attached the .ma file below!

Hi!

Your selectionlist is your list of arguments in this case.

The mirror joints tool only works with one selected joint, thats why you get the error when you have both arm and leg selected.

Mirror joints will give you the best result if you have a joint that sits on your mirror axis. So create a joint on world origin, parent arm and leg under it and then mirror that joint. Afterwards unparent everything from that joint again and delete it.

Also you need to mirror on the YZ plane not XY if your model is facing Z forward.

I hope it helps!

Mirroring joints individually did the trick! Thank you so much!
