In response to post #9174958.
We actually created multiple instances of her, which also allowed each preset to keep a separate inventory, then I created a custom script to allow the changing between them. It also allowed for multiple body types in the same ESP, which was nice. We are going to update the other mods to use the same type of in-game changer. It does cause a couple issues with marriage, which is why it is disabled now. We have a solution for the vanilla version, but really need to dive into how to handle any mods out there that could change those functions.
You mentioned SKSE. I've not really explored that area yet, and was just working within the bounds of the original vanilla game. Are there any areas or methods that SKSE would allow for more flexibilty? I would love to know more, and will start researching more myself in that area. It may be exactly what I'm looking for in the long term, especially if there is a way to directly interact with the files or redirecting pointers to different NIF files.
