Blender: How to Mirror Weights

When weight painting if you don’t enable X-Mirror in the Options tab, you’ll end up weight painting only one side of your model. Given that weight painting is a pain in the butt, you wouldn’t want to go through the excercise of trying to duplicate the weights on the other side. This short video shows you how to mirror the weights to the other side. Note your bone names need to be named with .L and .R at the end of the names.
