HIMBO is an overhaul of the Human/Half-Elf/Elf/Drow and Tiefling bodytype 2 that enhances their muscle definition and silhouette via both mesh and texture edits of the body as well as refits of vanilla armor and a selection of modded armor.  

💪 More Muscular Mesh (Model): 

Hum/Elf/Drow Mesh Changes

- Larger pectorals, broader shoulders, more muscular upper back, larger biceps and triceps, thicker forearms, larger glutes, and less skinny thighs and calves.
- Slimmer waist.
- More masculine butt shape.
- 3D nipples. 

Tiefling Mesh Changes

- Same enhancements as Hum/Elf/Drow.
- Tail has been moved further back to accommodate the bigger glutes.
- Nipple placement moved to match the Hum/Elf/Drow mesh.

💪 More Muscular Maps (Skin Texture):

Hum/Elf/Drow Mesh Texture Changes

- More defined back and arm muscles, pectorals, hands, and feet.
- More pronounced abs.
- Both hairy (Humans/Half-elves) and hairless (Elves/Drow) textures.
- Companions specific versions of the texture for Astarion, Gale**, and Wyll.* 

*Wyll also has an slightly different texture for his horned form if using Unique Companion Assets.
**Gale's god form has also been HIMBOfied.

Tiefling Texture Changes

- Same enhancements as Hum/Elf/Drow.
- Upscaled texture to not be super pixelated.
- Fixed vanilla weird smudge on abdomen.
- Attempted fix of the vanilla awkward squarish texture where the tail and butt meet.
- Added skin texture/depth variation from the human skin to make the tiefling skin closer to their heads' level of detail.
- More detailed nipples that have been moved to line up with the mesh and Hum/Elf/Drow.
- More human-like belly button that has been moved up to more closely match human proportions.
- HIMBO tiefling texture has also been applied to bodytype 4 (strong) tieflings in the Default Replacement version.
- Optional Tav-only (KAVT/UTAV/CCO) version with less pronounced body freckles.

💪 More Muscular Menswear (Armor Refits):

Armor Changes

- Almost all vanilla armor and clothing for the body slot have had their meshes refit. (Including physics and LODs)
- Almost all vanilla gloves and boots have had their meshes refit.
- Almost all vanilla cloaks and capes have had their meshes refit.
- A selection of modded outfits have had their meshes refit in optional patches, with more refits on the way.
- This took so much fucking time.

The HIMBO Nexus page has much more information such as descriptions of the various versions, mod requirements, and installation instructions.

The body mod itself is hosted on Nexus to be able to properly link all the different versions to their requirements. Refits of modded outfits will also be posted both there and here.

Currently only a handful of the modded outfit refits are published, but I have a backlog of over 80 either mostly complete or in-progress outfits. See the following Google Sheet of modded outfit refit progress:

Many of the modded outfit refits will remain Patreon member-exclusive. (Membership is 100% free.)
