In my first entry, I'd like to talk about the Fores New Idles in Skyrim mod. I can't stress enough, how important it is.

When I first stumbled across this site and found all those wonderful mods, I just wanted to play them right away, and did not really want to bother with the technical details of how to get them running. That was a big mistake. Some posts I have read seemed to suggest that Vortex (the mod manager I am using {I'm assuming that if you're reading this, you're a noob like me, too} – you can't do without one, unless you are a wizard of some kind) is entirely fool-proof and you basically just drop your mods in there and that's that.

And FNIS seemed to me just like one of many mods, of no particular importance, what is the main point I want to bring across here: it isn't just another mod. It's absolutely essential, and its absolutely essential to get it working properly. Another such tool is the SKSE, a requirement for pretty much all mods, but that's much easier to figure out.

The FNIS does have a VR version so make sure you install that, rather than any other version. I'm not posting the link here for now (or maybe ever), because I'm too lazy for that and there are posts doing this very well, if you look for them. But, eventually, once I verify my build is stable enough, I might post it here along with the entire mod order I am using.
From what I understand, FNIS is basically a tool that processes additional animations so that Skyrim can understand them. And if you mess it up, you will get crashes, i.e. "CTDs", and it will break your game. Using FNIS isn't very intuitive, but when you know how important it is, there is information out there, how to set it up.

Once you have FNIS installed properly (note: this encompasses the manual editing and copying of an .ini file – you will be prompted to do this by FNIS itself, if you fail to do this), watch this video: https://www.youtube.com/watch?v=sYEAnTdZb-s&t=912s

This really opened my eyes and resolved 80% of the issues I was having.
So the lesson I took here is that some mods are more important than others, and you will be well advised to take the time and study how to use them, because there's no way around it, and if you don't, you'll just waste time making broken builds like me, and eventually you'll have to learn about this stuff anyway.

I was lucky enough that my first build, by some divine miracle, kind of worked (the game did not always crash, merely a lot), even though, from a FNIS perspective, as I now can see, it was a total disaster. That kept me going. I attributed the issues I was having to incompatibility of the VR version of the game with SE mods, but once I gained some rudimentary understanding on how to use it properly, it turned out that most of them actually work just fine.

So the lesson here is, don't give up, most SE mods probably will work in VR, and if not, sooner or later, someone will patch them, as every day some Skyrim gamer somewhere gets a new VR headset and once you have it, there's no going back. Understandably so, because, especially in combination with BDSM-themed mods, the VR experience brings the game to a whole new level. It just blew me away.
