esm files when I started the CK and got the 'multiple masters' error, just Skyrim/Update/Apachii and also the 3DNPC.esp. Wish I’d found this ages ago, since exporting facegen has a hissy with custom headparts. I can finally make my older dude follower based on a younger dude design I like, cause it works for complexion too. You can literally make a blonde have black hair, vice-versa, etc.
