"Bad news, guys. There won't be any animation mod with plenty new animations in the near future. Whatever new animation you see, it's a modification of an existing file of the game, and REPLACES that animation. For example, this "Lydia Adult Show XXX" replaces "enter_bedroll", and whenever one NPC is required to run the original enter_bedroll in the game, s/he will run this sex animation instead.

And I doubt that you will find that many animations in the game, which are there for no reason, and can be replaced without breaking the game.

The problem is that Havok (the new animation engine) anims are much more complicated than the old Gamebryo/NIF format. And although two third of their tools are publicly available, one third (Behavior) is not. And even if you "find" a version, Bethesda has not released the files necessary to feed this tool. (hkx behavior files are only a stripped version of what you would need to modify).

And defining additional idle animations is only one of probably many things of what is hidden in these behavior files.

So unless a highly intelligent programmer finds a way to hack those behavior files (and possibly implements an idle manager on top of that, so different animations mods won't be automatically incompatible with one another), there will be no new animations. At least in a way that the rest of Skyrim will work as before."
