UPK Explorer for UE3 v2.2.2.0  

This tool is compatible with most Unreal Engine 3 games (and their DLCs) and will allow you to:

• Export textures as DDS files
• Create texture packs from your modified textures. The texture packs are installed with another tool called TFC installer. Mod users will need this tool to install your texture pack. The original package compression will be preserved.
• Create HD texture packs (upscaled textures are supported)
• Advanced mode: Inject textures directly into a new package (useful for creating custom DLC skins in certain games)
• Advanced mode: Import/export objects (can be used to swap meshes, materials etc... but not everything will work!)
• Advanced mode: Package Editor: Rename objects, modify object properties / name table / imports table and save a copy of the package. The original package compression will be preserved.

Check the instructions in the exe's "Documents" folder

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.
