you should have just emailed me :) i dont browse the forums much so i only accidentally stumbled upon this thread. im pretty sure this is in the readme. you can just select the head and turn the irina morph to 0, and then inject whatever SP3 morphs you would like. it is all injected together, for simplicity's sake, but then you can just dial down the morphs however you see fit. if you wanted to, you could create something halfway between irina and SP3 by turning all of the irina dials to .5000, and then even furthher customise it by injecting and dialing the SP3 body morphs.
