I am trying to rig my pig, but I keep running into issues with weight painting. I will have the bones all set up, and whether I do automatic or try to do it manually, I will get the left side painting okay, but the right side will seem to effect the same parts.

For example, I set up for automatic weights, and on the left foot, things looked fine. When I switched over to the right, half the right foot was painted, but the other half on the left foot was painted. If I fix it on the right foot, then the left foot is messed up that same way.

Can someone please help me out with this?
