[Solved] ART tool Symmetry error


When you’re using the ART toolset in maya and that you press the symmetry button, It may happen that you encounter the error “RT_skeletonBuilder_UI.py line 11381: setAttr: The attribute ‘calf_mover_r.overrideColor’ is locked or connected and cannot be modified” or that the symmetry option isn’t effective (nothing happen on the opposite arm or leg).

It’s probably because your character is inside a layer like mine was. What you have to do is to simply free him from any layer (Select your character → Right click on the layer → Remove selected objects).

I Hope this will help someone :).
