NativeTextureExporter

Primarily intended as a quick fix for black textures that appear in custom scenes.

Exports native Bannerlord textures referenced in custom material files of a mod.

A command‑line utility that extracts native game textures referenced by custom material files in a mod, saving them to a folder for import. After running the tool, use the usual modding workflow to scan for changes and import the exported textures into the mod.

What it does

• Reads native asset files from the game's native assets directory.
• Scans the specified mod folder for material definitions.
• Identifies texture references in those materials that come from the native assets.
• Copies the required native textures (DDS or PNG) into /AssetSources/vanilla_texture_reimports.
• Ignores textures that have already been exported to avoid duplicates.

Workflow

• Drop Bannerlord.NativeTextureExporter.exe to TPacTool's folder near TpacTool.exe
• Open Command Prompt or Windows PowerShell and cd to TpacTool's folder
• Run:

.\Bannerlord.NativeTextureExporter.exe "D:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\Native\EmAssetPackages" "D:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\YOUR_MOD\Assets"`

(change paths accordingly)

• No output for some time, then it will produce:

Finding materials in folder 'D:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\YOUR_MOD\Assets'
Found material 'lt_mortas_crown_with_wimple'
Found material 'lt_coat_of_plates_black'
Found material 'lt_coat_of_plates_grey'
Found material 'lt_coat_of_plates_piast'
Found material 'lt_coat_of_plates_pomerania'
...
Found material 'lt_saddle_dark2'
Exporting texture 'banner_battania_n' into D:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\YOUR_MOD\Assets\..\AssetSources\vanilla_texture_reimports\banner_factions
Exporting texture 'banner_battania_s' into D:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\YOUR_MOD\Assets\..\AssetSources\vanilla_texture_reimports\banner_factions
Skipping: banner_battania_n has already been exported
...

• In \YOUR_MOD\AssetSources\vanilla_texture_reimports you will find exported native textures:

• Now you can go to the Editor and reimport the textures.

To be safe, I changed the texture names, imported and assigned them to the custom materials.

Maybe it is not necessary, but it is better not to overwrite the native textures - in my understanding if TW will change them, the change will not be visible with your overwrites.
