A Java tool to export Fortnite .umaps and a Python script to import it.

• Before running the tool you need to have 64-bit Java installed. Get it here. (choose 64-bit Offline)
  32-bit Java won't work with this tool!
• Extract the zip file
• If you want to export from Fortnite, execute Fill Fortnite AES Keys.bat
• Edit config.json to suit your needs
• Execute Run Exporter.bat
• Make sure you have the Blender PSK import/export plugin at least version 2.7.13 installed. If you use prior versions of the plugin the scaling of the props will appear broken.
• In Blender, import the python file as a script (via scripting tab)
• (Optional) If you want to see the output of the script, show the system console (Window > Toggle System Console)
• Click Run Script (Alt+P), Blender will freeze if all goes well
• Profit!

• PaksDirectory: Path to the Paks folder. Backslashes must be doubled like this: \\.

• UEVersion: Unreal Engine version. Supports up to UE4.26.

• EncryptionKeys: List of AES keys to use for loading the paks

  • Guid: Identify a pak by its encryption key GUID. Use 00000000000000000000000000000000 (32 0's) to refer to the main paks.
  • FileName: Alternatively, you can use this to identify a pak by its file name.
  • Key: The pak's encryption key, in either hex (starting with "0x") or base64.

  Example for main paks:

  {
    "Guid": "00000000000000000000000000000000",
    "Key": "0x36983D73A17CAF253F9D1A322A79D6DC53D8E81B661B7564343F41D4835275D5"
  }

• bDumpAssets: Save assets as JSON format, useful for debugging.

• ObjectCacheSize: Configure the object loader cache size to tune the performance, or set to 0 to disable. Defaults to 100.

• bReadMaterials: Export materials. Materials are experimental! Not all imported materials will be perfect. Min. 24GB of RAM recommended!

• bExportToDDSWhenPossible: Prefer PNG over DDS? Set this to false and textures will always be exported as PNG. Warning: Export times will significantly increase when this is set to false! Defaults to enabled.

• bExportBuildingFoundations: You can turn off exporting sub-buildings in large POIs if you want to quickly port the base POI structures, by setting this to false. Defaults to enabled.

• bUseUModel: Run UModel within the exporting process to export meshes, materials, and textures.

• UModelAdditionalArgs: Additional command line args when starting UModel.

• ExportPackage: The .umap you want to export. Accepts these path formats:

  • /Game/Maps/MapName.umap
  • GameName/Content/Maps/MapName.umap (file path)

  These are accepted for games with I/O store (.utoc and .ucas):

  • /Game/Maps/MapName (package path)
  • /Game/Maps/MapName.MapName (object path)
  • GameName/Content/Maps/MapName (file path without extension)

  For assets in Fortnite game feature plugins:

  • For example the full file path is FortniteGame/Plugins/GameFeatures/GameFeatureName/Content/Maps/MapName.umap
  • You have to convert it into /GameFeatureName/Maps/MapName which is the package path that is supported by this tool.
