Two Campaigns, One Install

Keep several total conversions installed (say LOTR, Europe 1100 and Game of Thrones) and switch between them in one click, without breaking any of them.

Download

Download the profile switcher (.zip): one PowerShell script and a README.

Why it works

• Total conversions don't need to be uninstalled to be turned off. Unticked mods in the launcher don't load. They can sit in Modules side by side.
• Your whole tick list and load order lives in one file: Documents\Mount and Blade II Bannerlord\Configs\LauncherData.xml.
• Save a copy of that file per campaign, and switching campaigns is just copying the right one back.

The script does that for you. It also saves your current list first, so any ticks you changed are kept.

Set up

1. Unzip the switcher somewhere permanent, for example C:\Modding\launcher-profiles.
2. In the launcher, set up your first mod list. Launch to the main menu once to check it works, then quit.
3. In PowerShell, in the switcher folder:

.\Switch-Bannerlord.ps1 -Save LOTR

1. Set up the next mod list in the launcher, then save it as another profile:

.\Switch-Bannerlord.ps1 -Save EoE

Switch

.\Switch-Bannerlord.ps1 LOTR
.\Switch-Bannerlord.ps1 EoE

It swaps the list and starts the game through Steam.

Desktop shortcut: right-click the desktop > New > Shortcut, and paste:

powershell.exe -ExecutionPolicy Bypass -File "C:\Modding\launcher-profiles\Switch-Bannerlord.ps1" LOTR

Make one per campaign.

VR

Add -VR and the script ticks BannerlordVR, loads a separate VR graphics file and caps the frame rate. Without -VR it unticks it and puts your normal graphics back. Graphics changes you make in-game are saved back to whichever mode you were in.

Things that are shared between campaigns

The script can't separate these, so plan around them:

• Autosaves. All campaigns share the same three autosave slots. Make a named save before you switch.
• Mod Options settings for mods used in both lists.
• Library mods. Some total conversions bundle their own (TAOM does). Others need the standalone Harmony, ButterLib, UIExtenderEx and MCM ticked. Get each profile right once, and the switcher remembers it.
• AI Influence keeps memories per campaign, so it's safe. Its logs and settings are shared. See AI Influence context packs.

Before the first switch

Copy your Game Saves and Configs folders somewhere safe. The script only touches Configs, but a backup costs nothing.
