Method 1: As of v1.02, extract the contents of the archive into your Sins of a Solar Empire folder (default C:\Program Files\Stardock Games\Sins of a Solar empire\) and run "MT Install.bat" that will automatically backup the original files to "MT Textures (backup)" and replace them with the new ones. If you as paranoid as I am, check the contents of the .bat file using a text editor. It's perfectly harmless.
Method 2: Allegedly, v1.03 will allow us to use custom textures without copying the whole 1Gb+ Textures directory into the mod folder. In this case, you may want to perform a "softer" installation of the pack by registering it as a game mod.
To do that (and to install any other mods), first you have to find the used by the game:
• Start the game and open the Mods screen. (Options->Mods).
• Click the "Show Mod Path" button.
• A dialog will appear telling you where to place your mods (e.g. C:\Users\\AppData\Local\Ironclad Games\Sins of a Solar Empire\Mods)
Go to this \Mods folder, create a new subdirectory, name it after the mod, extract "MT Textures" from the archive into that subdirectory, and then rename "MT Textures" into "Textures" to make it visible by the game. Restart the game, and enable the use of the mod through the Mods screen. Piece of cake.
