BlenderUmap

A Java tool to export Fortnite .umaps and a Python script to import it. More games will be supported as time goes on.

Usage

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!
