I managed to do this years ago but I've completely forgotten how this all works. I'm trying to make a COTR follower with KS Hairdos and features from Marks of Beauty. I can't remember how I did it before in a way that didn't have me include all the needed meshes and textures from those mods with it. I keep hopping between old bookmarked tutorials and confusing myself further.
In most of the tuts I find the files are all included as a standalone, so how do I just have them be requirements? So far I've ESMified COTR, KS, and MoB. While COTR seems fine and I can find the hair I need from KS in CK object window, the KS hairs don't show up in the drop down menu under base head parts. Can't seem to find the freckles I need from MoB in the object window either. Anyone have any tips or tut links that can jog my memory a bit?
