X Mirror and copying weight paints I'm a bit confused with the X Mirror option and how you're supposed to copy weight paints from one side to the other. Is X Mirror supposed to work by painting the opposite side automatically as you paint the other? Or am I misunderstanding how it works. Either way, it doesn't appear to do much for me. Failing that, how am I supposed to copy my weight paints from one side to the other?



Thanks
x-mirror in weight paint mode is meant to mirror your actions between mirrored groups.

Let's say you have group four your right and left arm. If you paint the weights in the left arm group, x mirror will do its job on the right arm group.

In order to paint in symmetry inside a single group, you need the purposely named symmetry tool :
