This is just a SSE conversion of the nice sit animations by person123456789. He has long left the Nexus but gave permission to use his mod as will as long as he gets credit, so here we are. Be sure to endorse the original mod: https://www.nexusmods.com/skyrim/mods/15674
Installation: Just select one of the three folders and drop the content in your data folder. I have just added a FOMOD installer that karlarsch3913 was kind enought to provide for you mod manager needs.
This will install the mod for all NPCs and your female character; if you only want the animation to be used by your character of specific NPCs/races, use the mod Dynamic Animation replacer.
Disclaimer: It's irrelevant if you think this mod is "unrealistic" or something of the sort (also, you need to get out more often, lulz); fortunately, the beauty of modding is that no one needs to download
anything he doesn't want, so, if you don't like the mod, keep your comments and just close the page.
I also can't take constructive criticism since I didn't make the mod and lack the knowledge to make adjustment/fixes. I just converted it for the enjoyment of those that don't know how.
If anyone's interested, I can add a version with the correct folder structure for DAR users to have the animation applied only to their character (and not NPCs).
