📋 About This Mod

THIS WILL BREAK depending on your animations, there's unfortunately nothing I can do

it all depends on how someone exported their animations more info on that below

Just a simple hkx skeleton that allows animators to animate the "pre" boob and butt bones

Works with any version of the SSE version of XP32 skeletons

When Installing have this mod as a higher priority(lower in your mod list) than any other XP mods you have installed, it'll overwrite a file from any of those XP32 mods

If you're an animator and wanting to animate the boob and butt bones you need to animate the "pre" bones, don't touch the 3bbb bones or actual butt bones, as the physics controls them, also your rig needs to support those bones

Factory Closed's Rig(Lover's Lab link) and my (soon to be re-released) 3dsmax rig both support these bones, I'm unsure if there's any Blender rigs that support those bones

Thanks to FactoryClosed for filling me in, the Reason why this breaks with some animations, is due to bone lists animators use when exporting their animations, a bone list needs to be in the order the bones exist in inside the hkx skeleton file, if someone exported their animations with a bone list that is in the wrong order or has different bones in the same location, it'll make the boob and butt bones sink

There's sadly nothing I can do about this, and tbh there's no point in this mod if the anims you have don't even have animation on the boob bones

mod authors could re-export their animations with the vanilla or regular XPMSE bone list and it'll fix it but it's a bit silly to expect someone

There's sadly nothing I can do about this, and tbh there's no point in this mod if the anims you have don't even have animation on the boob bones

You can read more about the issue here (NSFW)

This mod is not compatible with CBPC Separate Anal Collisions from Lover's lab

🤖 AI-enhanced — based on mod data

XP32 Maximum Skeleton HKX Addition is a simple hkx skeleton file for Skyrim Special Edition that lets animators animate the 'pre' boob and butt bones, working with any SSE version of XP32 skeletons. It requires higher priority in your mod list to overwrite other XP mods and may break with animations that don't use the correct bone list order.

✨ Key Features

Adds a simple hkx skeleton that allows animators to animate the 'pre' boob and butt bones
Works with any version of the SSE version of XP32 skeletons
Requires higher priority in your mod list to overwrite files from other XP mods

📊 Pros & Cons

✅ Pros

  • Niche tool for animators who want to add physics-driven boob and butt movement (333 endorsements)
  • Simple install: just drop the file and set priority
  • Works with any SSE XP32 skeleton version, so no version hunting

⚠️ Cons

  • Will break with animations that don't have the correct bone list order, causing boob and butt bones to sink
  • No point if your animations don't already animate the boob bones
  • Compatibility risk: may conflict with other XP32 mods if not placed correctly in load order
🎯 Is This For You?
For Skyrim SE animators who want to create animations with physics-driven boob and butt movement using the 'pre' bones. Also for mod users who have animations that already use these bones and want to ensure compatibility. Skip if you're a casual player looking for visual upgrades—this is a technical skeleton tweak.
📦 Install:Easy· Under 1 minute

💡 Beginner Tips

  • Place this mod lower in your mod list (higher priority) than any other XP32 mods so it overwrites the skeleton file.
  • If you're an animator, animate the 'pre' bones, not the 3BBB or actual butt bones, to let physics handle them.
  • Check your animations' bone list order—if they're not in the same order as the skeleton, expect sinking issues.
