How to use wallpaper engine packs:

Note: You need Wallpaper Engine to fully use these!

1. Extract location of your choosing
2. Open Wallpaper Engine
3. Open from File (located bottom left)
4. Navigate to location of where pack was extracted and open file named scene.json

Some of these are available at my Steam workshop as well:
