I have made a rigged right hand for a character and I'm trying to mirror it to make a left hand. Please refer to the image
It doesn't seem as if I could use the mirror modifier to do this. If I select everything the modifier tab disappears. I tried to do this in a seperate file that only contains the hand and its rig, and selected the parts of the hand without the rig; was able to add a mirror modifier but as soon as I tried to select a reference object I get an error message at the bottom saying failed to set value.
Please help me with this.
