Mappings

Mappings (.usmap) are needed for viewing most UE5 games' assets. They can be extracted a few ways, but it's a good idea to check if someone else has dumped them already. The FModel Discord's Game Compatibility forum has many mappings uploaded, as well as this Unreal Mappings Archive by TheNaeem.

How to extract Mappings

Method 1

1. The easiest way to get your game's mappings is by using TheNaeem's Unreal Mappings Dumper. Download the .dll from the releases page.
2. Run your UE5 game, and use a DLL injector of your choice to inject UnrealMappingsDumper.dll into your game.
3. If it worked, you should see a Mappings.usmap file in the folder where the game's "xxxx-Shipping.exe" is.

Method 2

1. Assuming Method 1 didn't work, you can use UE4SS. Download the .zip from the latest release, and extract it to your game's Game\Binaries\Win64\ folder.
2. Open UE4SS-settings.ini and change the following:

MajorVersion = 5
MinorVersion = x
ConsoleEnabled = 1
GuiConsoleEnabled = 1
GuiConsoleVisible = 1
GraphicsAPI = y

x being your game's secondary version (5.x), and y being the graphics API your game uses (dx11, opengl).

1. Save the .ini and run your game.
2. A GUI like this should open in the background.
   
3. Go to the Dumpers tab and press the Generate .usmap file button.
   
4. If it worked, the Console tab of the GUI should say something similar to:

[xx:xx:xx] Mappings Generator by OutTheShade
Attempting to dump mappings...
Port of https:// github.com/OutTheShade/UnrealMappingsDumper Commit SHA 4da8c66
[xx:xx:xx] Mappings Generation Completed Successfully!

You'll find the Mappings.usmap file in the folder where the game's "xxxx-Shipping.exe" is. You can delete all UE4SS files after this process.
