HDT BBB Bounce for SAM 1.5

   (4 reviews)

About This File

Add HDT butt, breast, and belly bounce physics to SAM's body mesh with this mod.

The bounce movement was kept clean and subtle, but there may be some distortion with certain body poses.  Due to the way the vertices were weighted, it's not recommended to scale the butt, breast, or belly bones.  Doing so will cause distortions in the mesh.  Use Samson/Samuel morphs instead.

An alternate version was created where the butt bounce encompasses the entire butt rather than just the lower half.  It's considered an experiment for now.

As of version 1.2, all the gaps in the wrists and neck have been fixed.  For completion sake, SAM's default underwear was weighted alongside the butt bounce, but there is a lot of clipping on the sides.  There won't be too much time spent on it since most players would opt for SAM's nude option anyway.

As of version 1.4, the default butt bounce has been removed and the alternate butt bounce version is now the default.


  • HDT-PE (classic Skyrim only) or HDT-SMP (SAM Light, SE only)
  • XPMSE or my modified SAM skeleton (info below)


Follow the installer to simply the installation process.

The default version (formally known as "global") is recommended if you don't use any other HDT-PE mods, specifically ones that modify the global xml file (SKSE\Plugins\hdtPhysicsExtensionsDefaultBBP.xml).  Most armor mods should be fine.

If you use female body mods with HDT, they have their own physics settings and may not look right on the male body.  Use the "actor" version instead which forces SAM's body mesh to use its own xml file (meshes\actors\character\character assets\malebody_hdtPhysicsExtensions.xml).  The only drawback to this is that physics for the male body will only be active on a naked characer.  Other physics-enabled mods that don't use a custom xml will use the global xml by default.

If you don't want to use XPMSE for whatever reason, you can use my modified SAM skeleton instead.  I added the butt, breasts, and belly nodes to SAM's skeleton as well as the changes from Realistic Ragdolls and Force.
