Some Brawl movesets mirror TransN by setting the scale to (-1,1,1). If this is done, the animations must be mirrored and culling must be reversed. It's easy to mirror the animations via Brawlbox's "Edit All" for Animation Data. A script to change Cull_Inside to Cull_Outside and vice versa would make converting models to mirrored movesets quicker.
