SexLab P+ Documentation

Documentation for SexLab Patch Plus, SexLab Scene Builder, and related mods

Installation Guide

A complete, step-by-step guide to installing SexLab P+.

Requirements

Skyrim Version

Current Builds (Legacy Versioning)

Version Support Level
1.6.1170 ✅ Fully Supported
1.5.97 ⚠️ Limited Support (based on Patreon funding)
1.6.640 ❌ Unsupported (will eventually crash)
Older versions ❌ Not Supported

GOG Users: Support is not guaranteed but will be investigated.

Future Builds (CommonLibSSE-NG)

Future versions of SexLab P+ will be compiled with CommonLibSSE-NG, making them version agnostic. This means a single build will work across all Skyrim SE/AE versions without needing version-specific releases.

VR Support

A VR version is being considered but requires external help and contributions. If you’re interested in helping with VR support, please reach out on the Discord.

Required Mods

Install these before SexLab P+:

Mod Notes
SKSE Match to your Skyrim version

SkyUI For MCM menus
Mfg Fix NG Required for expressions
BEES Only if on 1.6.640 or lower
AnimSpeedSE To control animation speed

Installation Steps

Step 1: Install Base SexLab

Install the base SexLab Framework first. This is a precaution as P+ will overwrite everything except the logo.

Step 2: Install Mfg Fix NG

Download and install Mfg Fix NG along with its requirements.

Step 3: Install SexLab P+

Download from one of these sources:

Critical: P+ must win ALL file conflicts. Let it overwrite every mod that touches base SexLab.*

*The only exception is HentaiRim for SLP+. It needs Papyrus functions that have yet to be added to the main scripts.

Step 4: Install Animation Packs

  1. Install the SLAL packs you want (but NOT the SLAL loader itself)
  2. Download the Automated.SLSB.Conversions package
  3. Install the conversions, letting them overwrite the SLAL packs
  4. Optional: If using any SLSB stand-alone conversions - skip this pack in the automated installer and let the stand-alone SLSB win any conflicts.

Your mod order should look something like this:

SexLab P+
├── [Animation Pack 1] (SLAL version)
├── SLSB Conversion for Pack 1 ← overwrites above
├── [Animation Pack 2] (SLAL version)  
├── SLSB Conversion for Pack 2 ← overwrites above
└── ...

Note: Until authors grant redistribution permission, you must download both the original SLAL pack and its SLSB conversion separately.

Note 2: At the time of writing we are actively contacting SLAL pack authors to help them migrate/provide SLSB conversions.

Note 3: SLAL aniamtion pack and SLSB conversion versions should match exactly (for example, if you have Billyy 9.6, only use conversions made for Billyy 9.6) to avoid T-Poses.

Step 5: Generate Behaviors

Run your behavior generation tool:

  • Pandora - Recommended. Use the latest stable version from Nexus.
  • Nemesis + FNIS - Usually preferred for stability, but it’s more tedious.

Step 6: Verify Installation

  1. Ensure no mods are overwriting SexLab P+ (unless specifically patched)
  2. Check for file conflicts in your mod manager
  3. Review your load order

Step 7: Test

Always test on a new save first!

Mod Manager Setup

MO2 (Mod Organizer 2)

Your left pane should look like:

...
Base SexLab
Mfg Fix NG
SexLab P+ ← wins all SL conflicts
Animation Pack 1 (SLAL)
SLSB Conversion Pack 1 ← overwrites SLAL pack
Animation Pack 2 (SLAL)
SLSB Conversion Pack 2
...

Vortex

Use load order rules to ensure:

  1. SexLab P+ loads after base SexLab
  2. SLSB conversions load after their respective SLAL packs
  3. No mods overwrite SexLab P+ files

For optimal physics and body support, see:

→ Recommended Mods

This includes body mods (CBBE 3BA, HIMBO, The New Gentleman) and other complementary mods.

Post-Installation

First Launch

  1. Start Skyrim and load a new save
  2. Wait for all mods to initialize
  3. Open MCM and find SexLab
  4. Configure settings as desired

Settings

P+ settings are save-agnostic—configure once and they apply to all saves.

Your MCM preferences are automatically saved to:

SKSE\Plugins\SexLabData\Settings.yaml

For advanced configuration of the enjoyment system, detection thresholds, and other framework internals, see the Settings Reference.

Common Issues

“Animations not playing”

  • Did you run behavior generation?
  • Is your behaviour generator putting files in the right place?
  • Are SLSB conversions installed and winning conflicts?
  • Do the versions of SLAL animation pack and the SLSB conversion match exactly?

“CTD on scene start”

  • Verify Skyrim version compatibility
  • Check for mod conflicts
  • Ensure Mfg Fix NG is installed

“MCM not showing”

  • Is SkyUI installed?
  • Verify you have the correct version of SL & SLP+ installed
  • Wait a few minutes after loading for mods to initialize

See Troubleshooting for more solutions.
