I created a model using RPG Graphics tutorials, and was about to begin weight painting. However, when I move one side of the armature, the other side mirrors its actions (model shown in tutorial does not do this). I would like to be able to move the sides independently. The right side of the mesh is mirrored from the left side. In edit mode, vertices appear only on the original side. Mesh on the original side bonds to armature, but that on the mirrored side does not; when I move the left arm, left arm mesh follows it, and right arm mesh mirrors it, but right armature does not follow. I have tried selecting all, pressing 'p', and using the separate options. Does not work.
