Schlong Physics Swapper - Automatic SMP and CBPC Switching

FLOPPY WHEN FLACCID • HARD WHEN ERECT

LOW AROUSAL  →  SMP  →  soft and floppy

HIGH AROUSAL  →  CBPC  →  erect and stable

Schlong Physics Swapper automatically changes the player's physics using arousal.

PLAYER CHARACTER ONLY

What it does

• []Uses SMP while soft and CBPC while erect.[/]

  []Switches automatically at the arousal level you choose.[/]

  []Gradually becomes erect instead of instantly popping upright.[/]

  []Lets you adjust the erect angle from 0 to 20.[/]

  []Restores the correct state after loading or resetting SMP.[/]

  []Supports SexLab P+ scenes and Procedural Penis Animations.[/]

  []Includes a simple menu, quick tests and readable problem reports.[/]

  []Uses no ESP and adds nothing to your save.[/]

  Quick installation

  • []Install the mandatory mods shown on the Requirements tab.[/]

    []Install SPS with MO2 or Vortex.[/]

    []For a new install, choose Install recommended settings. When updating, choose Keep my existing settings.[/]

    []Let SPS win conflicts for its included CBPC files.[/]

    []Fully restart Skyrim and launch it through SKSE.[/]

    []Open SKSE Menu Framework → Schlong Physics Swapper and use Automatic mode.[/]

    Supported setups

    SPS supports:

    • []SOS AE[/]

      []Legacy SOS[/]

      []The New Gentleman[/]

      []OSL Aroused[/]

      []SLO Aroused NG[/]

      []Classic SexLab Aroused Redux[/]

      Your active schlong must be a compatible six-bone setup with its own SMP physics XML. SPS does not include a body, schlong mesh or SMP XML.

      SexLab P+ and PPA

      SexLab P+ and PPA are optional.

      By default, a receiving/bottom scene keeps the state from before the scene:

      • []Soft stays soft.[/]

        []Hard stays hard.[/]

        []Penetrating uses CBPC.[/]

        You can change this from the Scene behaviour page.

        When PPA is active, PPA controls the angle while SPS only chooses SMP or CBPC. This stops the mods fighting each other.

        Important notes

        • []Physics Editor: Works alongside SPS in my testing. If you notice bouncing or the physics fighting each other, let SPS control the schlong physics and disable any overlapping settings in Physics Editor. [/]

          []SLO Aroused NG users should leave Use SOS disabled.[/]

          []Classic SexLab Aroused users should leave Enable SOS disabled.[/]

          For Mod Authors

          SPS includes an optional compatibility API for SKSE plugins. Other mods can request SMP or CBPC, read the current state and tell SPS when they reset physics without making SPS a required dependency.

          Development note

          I have been modding Skyrim for around ten years, but I am still learning how to create mods. SPS was made with user-directed AI assistance, then repeatedly built, tested and fixed in my own game.
