Anatomy Engine

by DuduPhudu·v1.2.14·Updated 2026-10-09

The physics engine behind Anatomy is available as OCBPC's cbp.dll. "Anatomy" (the entire CBBE family, including 3BBB, and BodyTalk 4 men) gives the body bones that are added at runtime, openings that respond to contact, lips that fit the objects in front of you, and through Rapport, facial expressions and eyes can also be displayed. There are also dual push fixations for sighting, single barrel collision and OCBPC.

Servo supports: her rubber openings open, wrap around and aim, and the male module's are aimed.

Body bones always come from bones (replicas of worn parts can no longer cheat the laws of physics).

Health checks will count Servitron and no longer mark pre-war spouses.

Fallout 4's body physics lets objects pass through each other and bounce back. The anatomy engine takes care of this, which is why anatomy works: when bodies come into contact, the genitals open and move, and the mouth follows the position of the lips, finding the right opening. It is a temporary replacement for OCBPC cbp.dll.

The Commonwealth Family: Raised Together

Work Relationships: Dominate scenes Chemistry: NPCs discover each other Overture: You convince others Anatomy: Working genitals, arousal and contact Anatomy Engine (this page): The physics behind them Silhouettes: Everyone has their own body Ivy's panties: All set up for you

New here? Arrangement guide: From the subject to the scene, in order, including what to bring and what to skip.

In short, what you get

Body parts touch and push against each other without any breaking or shaking. Breasts, hips, anywhere physical files collide.

Anatomy: Genitals open on contact, with suitable openings found in any animation pack.

Anatomy: A mouth for lips, and our own sex sounds in the scene.

With Laporte: Her face and eyes are present in the scene, including occasionally looking up into her partner's eyes.

What you need is: F4SE and a runtime database. You also need anatomy for genitals, mouth, and aiming.

The process is: install with Vortex or MO2 and let this engine cbp.dll outperform any other. Details: Before you start playing, below.

what is

The dissection engine (fo4-ocbpc) is OCBPC, the extended version of collision physics cbp.dll. It is a fork of ericncream OpenCBP_FO4, the code behind OCBPC 0.3, and it replaces that file.

It's the engine in Anatomy and what allows Rapport to dominate the face in the scene. Without Anatomy, it's OCBPC fixing collision bugs: every OCBPC configuration is better suited for it.

Principle: Physics engine.

What do you get?

There were sex sounds coming from the engine. The sounds built into each animation package are muted in the scene. Our own repertoire, with the volume to match, the depth and speed of each stroke to match. Sexual Arousal and Sex→

The canal held him captive. The path it now follows is 12.5 deep (previously it was 5.6 deep), with walls wrapping around it, wrapping tightly around it. There are 48 canal bones per frame, 6 8-rings; same as Anatomy 1.2.4.

Men Too (Male-Male): Men, even in the female-only preset, are modeled as anatomical skeletons aimed at the male anus.

No jitter in contact: close contact is firm and will not jitter when squeezed.

Health Checks: After each load, Anatomy_Health.txt names the engine, presets, bodies, and characters that move; after your first AAF scene, it adds who is in it, whether her gap is found, and what to fix if it isn't. The message box only appears for real problems.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
