A brief demo showing you how the Red9 Studio Pack deals with Mirroring and how to setup your rig to work with the systems. The systems rely on 2 main attribute markers (mirror side and mirror index) and a third optional one (axis).
Just to clarify this, if the axis attr is not found then the default channels are inversed (tx, ry,rz). If the axis attr is found and has no data, ie it's a blank string, then no inverse takes place, left and right pairs are just copied across. If the attr is found with valid channels then these will be the ones inversed. You can add any channels to this not just the standard ones in the ui, so if your foot system has side-roll and that's required to be inversed in the mirror process, then add it to the attr.
