I begin by saying that I was unaware of the existence of this animation. I had already experienced the classics: Troll, Gargoyle, Rieklings, Drugher, Falmer.
Then I asked myself: does it also work with horses? The animation was activated with Match Maker.
Now, I'm going to focus on finding 3 horses in Skyrim to see if that animation exists as well.
After modifying Match Maker, nothing is impossible (or almost) for me, animation is enough Match Maker extended actors
