Hi Aardvark, regarding that flex in the Corset costume that I asked you about some days algo, so that the corset could be used over the BAS and Student shirts, I was talking more about just a helper flex which scales up the corset, since rootTransform scaling, Spine scaling, etc, won't work when locking the model. So nothing like a specific custom flex that you had to retroactively maintain when adding or changing other models, just a basic scaling flex for the corset, more like a helper flex to being able to fliddle a bit with other flexes to make it possible. Combining that flex with other flexes in the corset, or in the model and the shirts, like corset_pinch and/or the breasts flexes, I'm sure it would be far easier to use the corset that way, even if it was not an "official" feature.
