How am I supposed to mirror my controls after resizing etc? It doesn’t do anything, I’m using the default Biped Template. See YouTube video: https://youtu.be/bvw4G9DKudQ?si=LFFie8EKDQok_gR3

Hopefully an error popping in script editor, could you paste it over?
Hi thanks for the reply! Here’s what Maya’s spitting out:
select -r arm_L0_fk2_ctl ;
# Traceback (most recent call last):

# AttributeError: 'str' object has no attribute 'nodeType'I got it working by fixing the code, it was a PyMel Python 3 issue. The issue occurred because Maya’s API returned node names as plain text strings rather than PyNode objects. I modified “mirror_controls.py” in the scripts → mGear → rigbits folder into this:
