Only vertical axis work in Morph mode while editing with the mouse
In Character creator 3 and Headshot you could control morphs by left clicking and moving mouse horizontal for scaling (?) and vertical for up/down editing of position e.t.c
In CC4 / headshot leftclicking and moving mouse vertically changes position as it should, but left clicking and moving mouse horizontally no longer do anything to scaling or whatever parameters it used to work with.
