Details
The new bones are:
4 Pecs/breast bones
9 Tail bones
1 Belly bone
2 Balls bones
7 Penis bones
2 Vagina bones
4 Anus bones
4 Tongue bones

They can be used for cloth physics already with the new Havok Blender addon, but they do not have their own collisions for now.

For mod authors who need extended skeleton bones for custom animations or creature mods. Skip if you're a player looking for gameplay changes—this is a behind-the-scenes resource.
💡 Beginner Tips
- If you're a mod author, load this as a master file in your modding tool so you can reference the new bones.
- Check the mod's posts or comments for any hidden usage notes, since the description is bare-bones.
- For players, this mod does nothing on its own—don't install it unless another mod requires it.
