How to install mods with TFC Installer

Multiple texture packs can update the same UPK. For instance, a mod that turns Robin's hair blond will not conflict with a mod that changes the colour of his suit.

The texture pack installed last will take precedent if the same textures are present in both packs.

"Uninstall All" will revert the game back to its original state. Only the original vanilla UPK is backed up automatically, not modded ones.

• Step 1 - Downloading TFC Installer

Download and run TFC Installer

• Step 2 - Selecting your game folder

Set your Game Directory. This will be the base installation folder. Eg; Steam\SteamApps\Common\Batman Arkham Knight.

• Step 3 - Selecting your Texture Pack/Game Patch

Click "Texture Pack/Game Patch" and navigate to the extracted zip of your mod. The Texture Pack/Game Patch folder will be the one with .tfcmapping and/or .packagepatch files.

• Step 4 - Installing the mod

Now that you have both the game folder and Texture Pack/Game Patch folder inputted, simply press "Update". Depending on the mod, you may have to update DLC files as well as base game ones.

How to create a texture replacement mod

• Step 1 - Extracting the textures

Open UPK Explorer, click "Open Game Folder" and select your game's install folder. For example, H:\SteamLibrary\steamapps\common\Dishonored, select the base game or DLC you wish to mod, then navigate to the "Extract Textures" tab and extract the textures you desire.

• Step 2 - Finding the extracted textures:

Navigate to your extracted textures. You will find them in UPK Working Folder. Ex; [UPK Working]\Dishonored\Exports\PF_DXT1.

• Step 3 - Editing your textures:

Open the DDS files from the Exports\PF_DXT1 folder with your image editor of choice, edit them as desired, then move the textures from Exports\PF_DXT1 to Imports\PF_DXT1.

• Step 4 - Creating the Texture Pack

Within UPK Explorer, navigate to "Create Texture Pack" you should see your modified textures in the list. Click on "Create Texture Pack" at the bottom.

• Step 5 - Applying the mod

With the texture pack created, open TFC Installer, input your game folder and mod folder and click "Update".

• Step 6 - Sharing the mod

To share your mod with others, all you have to do is zip up your MyMod folder. It is recommended to rename your MyMod folder to something unique beforehand so that it doesn't get overwritten by other mods.

How to convert texture mods from Texmod to TFC Installer

• Step 1 - Extracting DDS files from the game

Within UPK Explorer, open your game/DLC folder and extract the required textures for the mod, for example, the skin textures for your character.

• Step 2 - Extracting Texmod's TPF file

Use TPFExtract.exe to extract Texmod's TPF file. If extracted correctly you should now see the textures in a workable format.

• Step 3 - Locating the extracted DDS files from UPK Explorer

Navigate to the textures you have extracted from UPK Explorer. You will find them in UPK Working Folder. Ex; UPK Working\Batman Arkham City\Exports\PF_DXT1.

• Step 4 - Converting the textures

Open the textures from the TPF archive with the image editor of your choice and save over the equivalent exported DDS files. It's important to keep the correct pixel format.

• Step 5 - Creating the texture pack

Move the DDS textures to the correct pixel format folder. Eg; UPK Working\Batman Arkham City\Imports\PF_DXT1 and then, within UPK Explorer, navigate to "Create Texture Pack" you should see your modified textures in the list. Click on "Create Texture Pack" at the bottom.

• Step 6 - Applying the mod

With the texture pack created, just use TFC Installer to apply the mod.

• Step 7 - Sharing the mod

To share your mod with others, all you have to do is zip up your MyMod folder. It is recommended to rename your MyMod folder to something unique beforehand so that it doesn't get overwritten by other mods.

Only share converted mods that you yourself have made, unless you have permission from the original author to convert it on their behalf.

How to convert texture mods from Resorep/Special K to TFC Installer

• Step 1 - Extracting DDS files from the game

Within UPK Explorer, open your game/DLC folder and extract the required textures for the mod, for example, the skin textures for your character.

• Step 2 - Renaming the DDS files

Rename the numbered textures from the Resorep/Special K textures folder to the names of the ones extracted by UPK Explorer.

• Step 3 - Resaving the DDS files

Some DDS files may need to be resaved to the correct pixel format with mipmaps generated.

• Step 4 - Creating the texture pack

Move the DDS textures to the correct pixel format folder. Eg; UPK Working\Batman Arkham City\Imports\PF_DXT1 and then, within UPK Explorer, navigate to "Create Texture Pack" you should see your modified textures in the list. Click on "Create Texture Pack" at the bottom.

• Step 6 - Applying the mod

Batman: Arkham Tutorials

How to create a new suit slot (DLC) mod for Batman: Arkham Knight

The following steps require that UPK Explorer is in "Advanced Mode".

You may need to decompress your UPK files before following this guide. To decompress, use Gildor's Unreal Package Decompressor.

The following steps may not apply to all games. For this example we will be using Batman Arkham Knight and creating a new slot for the Dark Magic Harley Quinn skin.

• Step 1 - Locating the files

For this mod we will need Harley Quinn's files. These can be located in the following directories: Playable_DLCHarleyQuinn_Std_SF.upk - steamapps\common\Batman Arkham Knight\DLC\313100\Content\BmGame\CookedPCConsole Showcase_Characters_Harley.upk & Showcase_UI_HarleyQuinn_SF.upk - steamapps\common\Batman Arkham Knight\BmGame\CookedPCConsole Open UPK Explorer and click Open Package File, then navigate to the Playable_DLCHarleyQuinn_Std_SF.upk file.

• Step 2 - Extracting textures

Go to the "Extract Textures" tab and click extract all at the bottom of the list. You will find them in UPK Working Folder. Ex; UPK Working\Batman Arkham Knight\Exports\PF_DXT1.

• Step 3 - Editing textures:

Edit your textures as necessary, save as DDS with the same pixel formatting as the original and move them to the correct folder. For example, anything modified from UPK Working\Batman Arkham Knight\Exports\PF_DXT1 belongs in UPK Working\Batman Arkham Knight\Imports\PF_DXT1.

• Step 4 - Injecting textures

Inject your textures by going to the "Inject Textures" tab. Make sure you see all of your textures in the list and click "Inject textures and save a copy". Do this for both Showcase and Playable files.

• Step 5 - Renaming strings:

Open your new "*_copy.upk files" and navigate to Edit Package>Names. You will need to change the names of the textures you have modified as well as the file names for showcase, icon and playable. For example the original strings for the playable file are "playable_dlcharleyquinn_std" and "Playable_DLCHarleyQuinn_Std_SF". Change these to playable_dlcharleyquinn_dmg and Playable_DLCHarleyQuinn_DMG_SF respectively and click "Save copy".

• Step 6 - Showcase_UI

Open Showcase_UI_HarleyQuinn_SF.upk and change its strings from "Showcase_UI_HarleyQuinn" to "Showcase_UI_GothicQuinn", save copy.

• Step 7 - Renaming the UPKs

Rename the *_copy_copy.upk files to "Playable_DLCHarleyQuinn_DMG_SF.upk" and "Showcase_Characters_GothicHarl" respectively. Also change Showcase_UI_HarleyQuinn_SF_copy.upk to Showcase_UI_GothicQuinn_SF.upk

• Step 8 - DLC Subfolders

Create your DLC subfolders. The folder will look something like this: "DLC\313100\DARKMAGICHARLEY". You will want to place your ini file inside DARKMAGICHARLEY\Config. Your new Showcase and Playable UPKs will go in DARKMAGICHARLEY\CookedPCConsole and your Localization file will go in DARKMAGICHARLEY\Localization\INT.

• Step 9 - The BmGame.ini file

The BmGame.ini file will go inside DARKMAGICHARLEY\Config. It should look something like this:

[Bmgame.RGameInfo] +DLCBundlesInstalled="DarkMagicHarley" ; Needs to be included to unlock default version of skin .ShowcaseItems=( Page="Players", Item="BatmanMk2", Skin="Playable_Batman_Std", Levels="Showcase_Ambient_Background|Showcase_Players_Batmanmk2", Camera="HumanL", SortIndex=100, Unlocked=TRUE ) .ShowcaseItems=( Page="Players", Item="GothicQuinn", Skin="Playable_DLCHarleyQuinn_DMG", Levels="Showcase_Ambient_Background|Showcase_Characters_GothicHarl", Camera="HumanM", SortIndex=500, DLC=TRUE, Unlocked=TRUE )

• Step 10 - The GFxUI.int file

The GFxUI.int file will go inside DARKMAGICHARLEY\Localization. It should look something like this:

[Showcase] GothicQuinn=DARK MAGIC HARLEY QUINN SKIN GothicQuinn_Desc=The darkness within.

• Step 11 - Showcase Icon Replacement

Now that you have your new suit slot ingame you will notice a duplicate Harley Quinn icon. To create a new one it is best to zoom in on Harley and take a screenshot. You will then want to open up the showcase_ui texture in UPK - Working\Batman Arkham Knight\Exports\PF_DXT1 and paste your screenshot over it, lining it up with the original as close as possible and save the texture with DXT1 compression, then inject as before.

• Step 12 - Sharing your mod:

To share your newly created DLC mod, simply zip the equivilent of your DARKMAGICHARLEY folder. You may also wish to create a dummy folder of the numbers, in case your mod uses assets from a particular DLC.

It is recommended NOT to use the DLC method to replace skins as this will cause conflicts with skins that use TFC Installer. Only use TFC Installer for replacing skins.

How to create a new Batmobile slot (DLC) mod for Batman: Arkham Knight

• Step 1: Follow the same steps as for the New Suit Slot guide. This time using Playable_BatmobileName_SF.
• Step 2: Open the UPK and navigate to the object editor.
• Step 3: Find the Batmobile_BatmobileName_Archetype package and rename it to Batmobile_Rocksteady_Archetype
• Step 4: Find the BatmobileName RVehicleBatmobile object and rename it to Batmobile_Rocksteady
• Step 5: Save copy, delete original and remove _copy suffix.

How to create make glowing eyes for Batman: Arkham Knight

The following steps require that UPK Explorer is in "Advanced Mode".

You may need to decompress your UPK files before following this guide. To decompress, use Gildor's Unreal Package Decompressor.

• Step 1: Open your Arkham Knight skin's UPK.
• Step 2: Go to Edit Package>Objects.
• Step 3: Find "Batman_BM3_V2_Eye_High_D2" and "Batman_BM3_V2_Eye_High_DS_7_D2", go to the "properties" tab of both and set LODGroup to "None".
• Step 4: Find Batman_BM3_V2_eyeball_MAT_INST, scroll down until you find "Glowing Eyes On Off", set this to 1.
• Step 5: Scrolling further down, all the way at the bottom you will find "Glow Colour", "Iris_ColourInner" and "Iris_ColourOuter". Set these to your desired colour.

A value of 1 is recommended for a comic book style of glowing eyes, values higher than 1 will over expose the bloom and may give an undesired effect.

• Step 6: Rename the "Batman_BM3_V2_eyeball_MAT_INST" as it is preloaded in the showcase menu and therefore glowing eyes will only work ingame.
• Step 7: Save UPK, delete original and remove the _copy suffix.

How to convert any UPK into a playable skin

• Step 8: Go to "Inject textures" and Inject all textures if you only have the modified "Batman_BM3_V2_Ben.Maps.Batman_BM3_V2_Wetline_R" texture.
• Step 9: Go to the Showcase UPK file of your mod and rename "Batman_BM3_V2_Wetline_Mat_INST" as it is preloaded in the Showcase and therefore it will only work in-game.
• Step 10: Save UPK, delete original and remove the _copy suffix.

How to swap Characters with New Suit Slots for Batman: Arkham Knight

The following steps require that UPK Explorer is in "Advanced Mode".

You may need to decompress your UPK files before following this guide. To decompress, use Gildor's Unreal Package Decompressor.

• Step 1: Open the UPK you want to convert to another character, for example, for this tutorial we will choose the Flashpoint Batman skin, we choose the UPKS with "FlashParadox" on it, "Playable_Batman_FlashParadox" and "Showcase_UI_BatmanFlashParadox"
• Step 2: Go to the Playable UPK, search "Playable_Batman_FlashParadox" and then replace with "Playable_DLCRedHood_FlashParadox", replace all then Save copy.
• Step 3: For the Showcase UI UPK, search for "Batman" then replace with "DLCRedHood", replace all and then save copy.
• Step 4: Delete the Original UPKs and remove the _copy suffix.
• Step 5: Create a Config folder, then a BmGame.ini file in it, it should look something like this:

[BmGame.RGameInfo] +DLCBundlesInstalled="RedHoodFlashParadox" .ShowcaseItems=( Page="Players", Item="BatmanMk2", Skin="Playable_Batman_Std", Levels="Showcase_Ambient_Background|Showcase_Players_Batmanmk2", Camera="HumanL", SortIndex=100, Unlocked=TRUE ) .ShowcaseItems=( Page="Players", Item="DLCRedHoodFlashParadox", Skin="Playable_DLCRedHood_FlashParadox", Levels="Showcase_Ambient_Background|Showcase_Players_DLCBatmanFlashParadox", Camera="HumanM", SortIndex=699, DLC=TRUE, Unlocked=TRUE )

• Step 6: Create a Localization folder, and with it a GFxUI.int file, it should look something like this:

[Showcase] DLCRedHoodFlashParadox=BATMAN FLASHPOINT | RED HOOD DLCRedHoodFlashParadox_Desc=Like father, like son

• Step 7: Test it in-game, if it works well then you have done it right.

Transformers Tutorials

How to create a replacement mesh mod for Transformers: Fall of Cybertron and Rise of the Dark Spark

The following steps require that UPK Explorer is in "Advanced Mode".

• Step 1: Within UPK Explorer, open your game folder and extract the required textures. You will also need to extract the \1 texture, if applicable.
  
• Step 2: Navigate to your extracted textures. You will find them in UPK Working Folder. Ex; UPK Working\Transformers Fall of Cybertron\Exports\PF_DXT5.
  
• Step 3: Edit them with your image editor of choice and then move the textures from Exports\PF_DXT5 to Imports\PF_DXT5.
  
• Step 4: Rename your texture files to match those of the ones you're replacing. Eg; TextureSets.RB_Bumblebee_Chest_TEXSET.RB_Bumblebee_Chest_TEXSET_Color_NormX and TextureSets.RB_Bumblebee_Chest_TEXSET.RB_Bumblebee_Chest_TEXSET_Masks_NormY, as well as the *..1 variants.
  

Make sure that you open the textures and generate mipmaps. Exported textures only have the largest mip and won't work if just moved from Exports to Imports.

• Step 5: Within UPK Explorer, navigate to "Create Texture Pack" you should see your modified textures in the list. Click on "Create Texture Pack" at the bottom.
  
• Step 6: With the texture pack created, just use TFC Installer to apply the mod.
  
• Step 7: With the texture pack now applied, find your mesh that you want to use. In this case we're using the RB_MegatronWFC2_CHARSKEL_Chest from UI_Lobby_M.XXX.
  
• Step 8: Once you've found your desired mesh(es), export them.
• Step 9: Find the mesh that you are replacing. In this case we're replacing RB_Bumblebee_CHARSKEL_Chest from L01_TheExodus_BASE_m.xxx.
  
• Step 10: Once you've found the mesh, click import and fill in the references in red using equivalent materials from the object that you are replacing.
  For example, if the reference is Exports: RB_MegatronWFC2_Chest_INST (MaterialInstanceConstant) you want to replace it with Exports[2867]: TR_BumbleBee_ROBO_p\TextureSets\RB_BumbleBee_Chest_Cust_MatINST (MaterialInstanceConstant).
• Step 11: Now that your mesh is imported, click save copy at the top right. With your new file, delete the original and remove the _copy suffix from the new one.
  

Material Editing

How to replace textures used in your Material

Step 1: Navigate to your Material or Material Instance Constant from the object editor.
Step 2: Replace the texture references from the Textures tab.

Some materials will be incompatible with some Pixel Formats. For example, if a material is expecting a V8U8 texture and you use a DXT1 to replace it, you may run into problems ingame.

Step 3: Save copy if editing a singular package or create game patch to save your newly edited material.

How to replace/edit properties used in your Material

Step 1: Navigate to your Material or Material Instance Constant from the object editor.
Step 2: Find the property you wish to edit, usually this will be in an array of either ScalarParameterValues or VectorParameterValues.
Step 3: Find the parameter name of the property you wish to edit; example: Cloth_Modulation_Color and change the parameter value as needed.

Do not use TextureParameterValues for editing texture references. Doing so will not update every reference of the texture. It is recommended to do so only in the Textures tab.

FBX Modding

Please note that Arkham Knight will need decompressed UPKs for most FBX modding. Game patches for Arkham Knight mesh mods may work but are somewhat unsupported for the time being.

How to Export FBX models from UPK Explorer

Open the UPK and go to the objects tab. Search for your mesh and if supported within UPK Explorer, you can and export it by clicking the "Export FBX" button.

Make sure to click "Export FBX" and not "Export" - "Export" will export a .staticmesh or .skeletalmesh binary file which will be incompatible with mesh editors.

How to prepare your FBX for UPK Explorer import

1: You must have proper bone weights assigned where necessary (not needed for static meshes).
2: You must have the same skeleton/bones as the mesh you're replacing.
3: You must have a vertex count of less than 65535 (some games will allow you to have more but for most games 65535 will be the limit per mesh.)
4: You must export with the recommended settings for each program.

How to Import FBX models to UPK Explorer (Game Patches)

1: Open the game folder and find the packages your mesh is in. It is easiest to do this from the meshes tab, selecting the mesh and then clicking the "packages" tab.
2: Using the list from earlier, find your mesh in each of the packages that the mesh is present in and select "Import FBX".

You may also need to create a texture pack if your mesh isn't just a simple geometry change.

3: Some of the materials may appear in the incorrect order. To fix this, you can select the three dots next to each material and assign a new Material or a new MaterialInstanceConstant.

How to Import FBX models to UPK Explorer (DLC/Suit Slots)

1: Open your UPK and change the names of the meshes and textures to something unique to your mod.
2: Find your mesh in each of the packages that the mesh is present in and select "Import FBX".

You may also need to inject textures if your mesh isn't just a simple geometry change.

3: Some of the materials may appear in the incorrect order. To fix this, you can select the three dots next to each material and assign a new material or a new MaterialInstanceConstant.

FBX Import: [version number] 64-bits is unsupported	Only 32 bit FBX files can be imported correctly. Please make sure that you use FBX 2014/2015 for the best results.
FBX Import: Mesh has no tangents	Make sure to select "Tangent Spaces" when exporting your FBX file.
FBX Import: Mesh has incorrect rotation/scale	Depending on the game and software used, you may have to try different combinations of rotation and scale for everything to look correct.
Mods not appearing ingame	Usually, this is due to the object being preloaded by another UPK. This will likely be a parent map or startup file. You can resolve this by adding new names and assigning them to your modified objects. If you are on a console, try removing installed game data (PS3) or clearing the caches and try to install your mod again.

Documentation - Basic

Texture Packs

A texture pack is a package that the users of your mod will download and install with TFC Installer. It is possible for the users to install several texture packs. if more than one texture pack replace the same texture, the last one to be installed will be the one replacing the texture. TFC installer can be used to uninstall all texture packs. If your modified texture was stored in a TFC instead of a package, your texture pack will have a custom TFC that will be installed in the game directory.

If your game has official DLCs, these are also supported and it is possible to create a texture pack for a specific DLC.

Texture packs are useful if you want to replace the game's original textures with your own (ex: a HD texture pack, a base game skin replacement, that sort of thing). Texture packs are not meant to be used to create new DLCs (ex: new skins), nor to install the texture pack and upload modified packages for the end users to override their game files.

It is recommended to not have any mods installed if you want to create a texture pack as some modding tools create packages that UPK Explorer may not be able to read properly

Texture Upscaling

If your game supports it, it is possible to upscale textures either for a texture pack or injecting textures directly into a new package. You should keep your uspcaled textures the same aspect/ratio as the original tetures and make the upscale multiples of 2x, 4x, 8x etc...

The max resolution used for textures in Unreal Engine 3 should support up to 4096.

The problem is some textures will not show up at the full 4096 pixel resolution if you do not modify your game's Engine.ini accordingly.

For example, in Dishonored, the file is located in My Documents\My Games\Dishonored\DishonoredGame\Config\DishonoredEngine.ini

You want to look for these entries (there are several): TEXTUREGROUP_World=(MinLODSize=256,MaxLODSize=2048,LODBias=0) and change them to: TEXTUREGROUP_World=(MinLODSize=256,MaxLODSize=4096,LODBias=0)

Do not do this for all entries as this seems to mess up the rendering of skies, shadows and so on. In the example above, the "World" texture groups consisted in the following entries: TEXTUREGROUP_World=(MinLODSize=256,MaxLODSize=2048,LODBias=0) TEXTUREGROUP_WorldNormalMap=(MinLODSize=256,MaxLODSize=2048,LODBias=0) TEXTUREGROUP_WorldSpecular=(MinLODSize=256,MaxLODSize=2048,LODBias=0)

Once you are done you probably want to set the file to read-only so the game does not restore the original values

Documentation - Advanced

Game Profiles

Game profiles are .xml files that can be found un the GameProfiles\ directory. They are used by both UPK Explorer and TFC installer to: - detect the game from the package version/licensee version found in the profile - map out the package folders - determine where the game's TFCs are located - determine what suffix the TFC files (Texture2D_xxx.tfc) will use. Warning: You should not modify this for the original game directories. - determine if the game exe needs to be patched for hash check (some game exe contain package names to validate with a checksum, the patcher removes these names so the packages can be modded) - enable or disable the use of TFC when generating a texture pack (so the texture pack will be generated with textures that have local only mipmaps)

When a texture pack is created, the game profiles is exported with it, and TFC installer will load that profile when the texture pack is opened.

Game profiles can also be used to exclude some packages or even directories. This is useful if you have modded files in your game installation that you do not want to be opened by UPK Explorer or modified by TFC installer.

SampleProfile.xml is provided as documentation and provides examples.

ID Remappings

Most games store the same textures as duplicate objects in several packages, for performance reasons. UPK Explorer attempts to group these identical textures together by identifying the textures using a generated name (which is group path\object name). However there are cases where the generated Id would actually group together textures that are not duplicates. This is where the IdRemappings.xml comes in. If no IdRemappings.xml can be found for your game under GameProfiles\IdRemappings, a new one will be generated when opening the game. It will log all package names as well as texture names that should not be grouped together.

When generating a texture pack, the IdRemappings is copied to the texture pack folder, and TFC installer will use it to inject the correct textures.

When you open a game with UPK Explorer that has a package that is not in the mappings file, you will be warned that your IdRemappings file might not be up to date.

There are two possibilities here: - if this is a modded package (like a new skin you downloaded), you should exclude that file from your game profile (See Game profiles instructions) - if this is an official package (following a game update...), you should delete your IdRemappings files, and the next time you will open the game, a new one will be generated for you.

If you create a new Game Profile for a game not on the compatibility list, please send the profile and idremapping file to us so we can ensure other modders will be able to modify the game.

New Package Files

If your game supports things like custom DLCs (new skins etc...), then you'll probably want to make a new package instead of a texture pack. The users of your mod will then copy this package into the appropriate folder and follow your instructions to enable the new DLC.

It is not recommended to use this functionality to override the game's "official" packages as it will conflict with other mods. It is possible to inject textures directly into the new package, as well as modifiy object properties (such as materials, names, etc...)

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

Select advanced mode, and open the package you want to work with, from your game installation folder.

From then on you can either inject textures into your package or modify object properties. Both will let you save a copy of the package. You will need to close the package and re-open it if it needs further modification (ex: after injection textures, open the copy to modify the properties)

Step 3: Inject textures (Optional)

See step 3 and 4 in "Instructions - Texture packs" about exporting and processing your textures. Click on the "Inject textures" tab. You should see your modified texture, and if you inject them in the package it will save a modified copy. No texture pack or TFC files will be created, the textures will be stored within the package to avoid conflicts with other mods in the installation folder. 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)

Go to the package tab and you will be able to see the package content. You can edit the names table (your game may or may not support longer names) You can also edit the properties of the objects under the objects tab This is useful if you are making a new custom skin and need to update material values, as well as giving your skin a unique name. Depending on the content of your package, you may also be able to swap meshes within the same package, or even make a mod that has nothing to do with textures... This might make the game crash, or not. You will have to experiment and find out. Once you are done you can save a copy of the package. You should close the package, and if you need to inject textures into, open the newly created copy.

You can then upload this new package, and the users of your mod will not need TFC installer as your package already contains all the modified textures and properties.

Package Patches

Package patches work just like texture packs and will require TFC installer for installation.

They are highly recommended for modifying the game's original packages, as TFC installer can apply several patches to the same package, making your mod compatible with other mods that also use package patches to modify the same packages as long as the edits do not conflict with each other.

It is highly recommended to create patches from a game installation that has no game patches installed, If you do not, the users of your mod will need to install the same package patches as you have, and in the same order.

To "Create a game patch", open the game folder in advanced mode. Go to the create game patch tab and select make edits to the packages you want to modify. Each time you click the "Create a game patch" button, a .PackagePatch file will be created for each of your modified packages. You can do that every time you are done editing a package, as each .PackagePatch file is a self-contained patch for the corresponding package. That means you can also delete one of the .PackagePatch file from your game patch if you changed your mind about this package being modified.

Just like a texture pack, a game patch can also contains package patches for DLCs, or even combined main game + DLC. To do so, simply move your .PackagePatch from the main games and DLCs in the same folder to make them into a single game patch.

Package patches can also include texture packs. To do so, either move the files from your texture pack into the same folder as the game patch (xml files can be overwriten) Or use the "Create texture pack" tab, which will export the texture pack into the same directory as your game patch. When using TFC installer, the packages will be patched first, and then the textures from the texture pack will be injected into it. The reason for this is to allow you to add new texture objects to the package, and then use the texture pack part of the patch to inject textures with custom TFCs into it. To enable this feature you should create your texture pack from an already patched game so your new textures are available for the texture pack creation.
