How to use:
Step 1: Set a working folder
The first thing to do is to set a working folder, for example c:\Workspace.
This is where file will be exported to, and textures will be imported from
Step 2: Open a package or open the game folder to view all textures at once
Select advanced mode, and open the package you want to work with, from your game installation folder.
Step 3: Export textures
Step 4: Inject textures
Once you've exported and edited your textures, put them in Working Folder\Game\Imports\[Texture Format] (texture formats MUST match)
Then go to the inject textures tab, click inject and save copy.
You should close the package at this point. If you need to modify object properties, open the newly created copy.
Step 4: Editing object properties (Optional)
To edit object properties you must be in Advanced Mode, go to edit package. Here you will be able to replace strings within the name table, including lengthening strings should you wish. In the objects tab you'll find the objects editor on the right. This is how you will edit properties and materials.
Once finished, click save, remove any _copy suffix and replace the original file. You should now see your mod ingame.
