I'm just doing this because it's a requirement for Turn of Seasons for Skyrim SE; I don't typically install mods without a Mod Manager handling basically everything. That and running FNIS is about the extent of my modding experience. I push a few buttons and the thingy just works most of the time. So this guide just assuming I know what this means when referring to the several folders this thing generated is, uh, very unhelpful to me, and I don't know anyone I can ask about it.
.... So, what does installing a mod from a folder usually entail? Can I use NMM or do I have to drop this somewhere manually?
EDIT: Also yes I did try to figure this out (It's not like this is forbidden knowledge, this is how people used to do it!) But when I tried it still tells me it can't find billboards or something of the like and to use TexGen, so I assume I am doing it wrong.
