This tool adds the roads using the png files in the "roads" directory to overlay onto the terrain LOD for Skyrim Special Edition.
Requires Python 3 with Pillow. I use version 3.8 to compile to ensure compatibility with Windows 7, but it can be compiled and used with the latest version.
Also requires texconv.exe from DirectXTex: https://github.com/microsoft/DirectXTex. It should be placed in subfolder called texconv, or modify code to point to your custom path.
