For animations, what is the difference between FNIS/Nemesis and OAR Open Animation Replacer (rewrite of DAR)?


Recommended Posts

So Nemesis is a better kind of FNIS, and OAR is a better kind of DAR?

But I read their entire descriptions and none seem to mention the other (kind).

Are these two competing ways to animate characters or can you combine them or did I misunderstand something completely?

Nemesis and FNIS basically do the same thing, with the exception that FNIS is the only one of the two that has creature compatibility.

DAR is the outdated version of OAR. You shouldn't be using DAR anymore, as any mod that used DAR will run with OAR.

Nemesis and FNIS are generally used for things like combat animations and new behaviors. As well as most NSFW animation mods.

OAR does a bit of both. Most of my idle animations, like weapon stance, sitting, etc... are run through OAR.

It can be a bit confusing when you first get into it.


Basically, Nemesis and FNIS change behaviors, which allows you to create NEW animations more freely. Things like dodging and True Direction Movement use Nemesis. These are things that weren't possible in the base game, so they require the Nemesis/FNIS engine to tell them where to go and how to act in the game.

OAR allows you to set conditions on animations.

Say you downloaded a new idle animation that has the player character rest their hand on their hip when standing still.

You can now go into OAR and set the condition for how often that happens, if it will fully replace the vanilla idle animation, or if it will play alongside it.


This can all get to be a little confusing because while both Nemesis/FNIS and OAR do similar things, the way they execute them is different. If you are going to be modding a bit, you will probably end up needing both. My best advice is to make sure that you read about them both on their respective mod pages, and get yourself a good mod manager. Many people recommend Mod Manager 2, I personally use Vortex, but it is up to your discretion.

Just make sure that whenever you are testing out new mods that you create a clean save for testing purposes, so you don't end up borking your save file.

In short, it would be a good idea to download both Nemesis and OAR if you plan to replace animations and add new combat behaviors.

I'm sure somebody else with better knowledge on the inner workings of these can give you a much better and detailed explanation. I'm just sharing with you what I've learned from my relatively short modding journey.

The distinction is simple.    FNIS or Nemesis are tools for adding entirely new animation events to the game.    I.e. if your script has: 
Debug.SendAnimationEvent(actor, "AnimationEventName"),  Skyrim's animation database must contain "AnimationEventName"  string key,   linking it to a particular .hkx file.    FNIS and Nemesis add new items to this database, thus allowing definition of entirely new animation events.

DAR/OAR allow  redirection of existing animation events, so that they use a different hkx file, based on specific conditions.

I.e. in vanilla animation DB, the "ChairIdle" animation event for female actors links to  meshes/actors/character/animations/female/chair_idlebasevar1.hkx

DAR or OAR, when certain conditions are satisfied, might use a different .hkx file when a "ChairIdle"  animation is invoked.

Wow thank you guys, that makes it real clear, I wonder why they can't write this stuff on the description pages.

Half the nightmare of modding is that these mod authors act like all the other mods don't exist or we're supposed to know all this when we search for something and get like 10 different "must haves" for one single type of thing.
