4K Normalmaps mod for IL-2 GBS (only required if you wish to use 4K textures)
1. Create 'Mods' folder in the root folder for your game (in my case E:\IL-2 Sturmovik GBS) if you don't already have one.
2. Unzip this file to the Mods folder. The folder structure should look like E:\IL-2 Sturmovik\Mods\4K Normalmaps\data
3 Enable via JSGME - Ensure that this is loaded BEFORE any other 4K texture mods
