The first thing you need to know is how to mod Skyrim ( LE or SE) with Mod Organizer 2 ( MO2). I know it can look confusing at first but it’s really not, I’ll explain as simple as possible. Nemesis is very easy to use if you follow these steps I’m about to show you ( or watch the video for a full demonstration). This is the successor to the older FNIS, which is now going into its well deserved retirement. There’s a new animation engine out there and it’s called Nemesis.
Playing Skyrim with new & custom NPC animations can be very refreshing.
