Each in-game character has a "ch pac" file that is located inside the /pac/ch folder of your game directory. These files will be named in one of two ways:
- WWE2K15 and earlier: all attires for a character are located inside a single PAC named chXXX.pac. - WWE2k15 DLC, WWE2K16 and later: attires are separated out into individual PACs named chXXXYZ.pac.
Both of these formats will work in WWE2K17. Additionally, the naming of these files is not as important as the naming of sub files.
Regardless of the format every ch pac will have a sub file or sub files in PACH or SDHC format. In WWE2K17 these sub files are named using unique string hashes which have no logical pattern, however they can be converted to use the classical naming schemes.
Classical Naming Scheme
The classical naming scheme for ch pach sub files is as follows:
ex: 000XXXYZ XXX = Wrestler ID Y = Attire Number (0 is attire 1, 9 is attire 10, etc) Z = Attire Type - sets whether an attire is an entrance or ring attire (2 is ring attire, 4 is entrance attire)
Note: If no ring attire exists, the game will read the ring attire for both entrance and ring. Also, if an attire is selected that doesn't have the ch .pac file installed, the game defaults to the first attire's ch*.pac file, which must always be installed.
Parts of a PACH/SDHC
0000 - A YOBJ file containing the main character objects.
000A - A Texture Archive containing the main textures and map textures.
000C - A Texture Archive containing the head and body textures.
00CE - A file which controls what parts of a character get rendered.
00CA - A file that controls animation of body parts and certain clothing parts.
2715 - A YOBJ file containing hair objects.
2580 - A file which controls hair animations as well as certain clothing animations.
25F4 - Seems to be a mix of the CA and CE functions (NEW in WWE 2K18).
4E22 - A YOBJ containing eyelid objects.
Changing Pac Slots
1) Put your ch*.pac files in a folder outside the game folder. 2) Rename your ch*.pac files to the correct chXXXYZ.pac format for your desired wrestler ID, Attire number and Attire type. 3) Download, install and start Custom Character Tools for your game version. 4) Click Install then CH-Pac files (Custom Character Tools 2018) resp. Install then Mass Character-Pac Installer (Custom Character Tools 2017) in the toolbar. 5) Select all the properly renamed ch*.pac files you wish to install. 6) Click install. The files will now be converted from the newer HSPC format to EPK8 format if needed, their EMD sections adjusted to match the file name's XXXYZ and installed into the \mods\ folder for mod release guideline compliance.
1) Open the PAC in HxD (or your hex editor of choice). 2) Search for the text “emd” (decimal not hexadecimal search). 3) Rename the XXX portion to the slot you want (see PAC Naming example above).
Repacking WWE 2K16 Style
Automated way using Custom Character Tools
1) Put your ch*.pac files in a folder outside the game folder. 2) Rename your ch*.pac files to the correct chXXXYZ.pac format for your desired wrestler ID, Attire number and Attire type. 3) Download, install and start Custom Character Tools for your game version. 4) Click Install then CH-Pac files in the toolbar. 5) Select all the properly renamed ch*.pac files you wish to convert and install. 6) Click install. The files will now be converted from the newer HSPC format to EPK8 format if needed, their EMD sections adjusted to match the file name's XXXYZ and installed into the \mods\ folder for mod release guideline compliance.
This way should work for any game.
1) Extract the SDHC file from your WWE 2K17 HSPC using PacTool, PacEditor or X-Packer. 2) Inject it into the pach slot of a WWE 2K16 PAC using PacTool, PacEditor or X-Packer. 3) Rename the pac and emd slot as needed.
Repacking WWE 2K15 Style
1) Figure out how many attire slots you’ll need (count ring and entrance attires as separate slots). 2) Download Pozzum’s dummy PACs from Smacktalks and choose the one with the amount of slots needed. 3) Rename the dummy PAC and all the emds inside accordingly for all the slots needed. 4) Extract all the SDHC/PACH files you want to include. 5) Open the renamed dummy and inject the SDHC/PACH files in the desired slots with PacTool.
Modifying Character Objects
Inside character pacs the basic YOBJs to look out for are 0000 (main yobj with all character parts), 2715 (hair parts), and 4E22 (eyelids). Additional YOBJs can be added with the following names: 001A, 001B, 2716, 2717, 2718, 2719, etc.
To work with these files slight modifications may be needed:
- If uncompressed file is named "FILENAME.jboy" then it should be renamed to "FILENAME.yobj". - If uncompressed file is named "FILENAME.yobj" change the header in hex to "JBOY".
Remove OBJs From a Character
Ex: Removing a character's elbow pad
1) Use ReShape or X-Rey to determine the object numbers. 2) Open the yobj in Anatomizer and move all undesirable objects to the bottom. 3) Change to render count in Anatomizer to exclude the undesirable objects and save.
Add OBJs From Another Character
Ex: Give Finn Balor the Big Dawg's vest
1) Find the yobj from the other character that contains the objects you want to add. 2) Open the yobj in ReShape or X-Rey and determine the numbers of the objects you want. 3) Open the yobj in Anatomizer and move the objects you want to the top. 4) Change to render count in Anatomizer to unrender everything except the objects you want and save. 5) Rename the yobj. *see note below 6) Add it to your base pach/sdhc with Pac Adder or create a new pach with PacTool or X-Packer. NOTE: The order of these files matter (they should be ordered in sequential hex). 7) Extract the textures for the added objects. 8) Create new texture archive in PacTool or XP with the main 000A textures plus the added obj textures. 9) Inject this new texture pac into the 000A slot. NOTE: Objects may not align properly so some 3D modelling of them may be required.
- Added yobj names:
- There are many options for this including 2717, 2718, 2719.
- The names between 5500 and 56FF should all work for 2K18, (whether these work in earlier games in undetermined).
- Do NOT use 001A and 001B. They were often used before 2K18, but do not seem to work properly in current games.
- Do NOT use 4E22. This was used in 2K15 mods, but is actually an animated eyelash slot in newer games, so anything in this slot will "blink".
Ex: Give AJ Styles the Andre afro
1) Decide what hair you want and find a character with it. 2) Extract the 2715 and 2580 files from the character with the hair you want. 3) Edit the 2715.yobj hair model in a 3D modelling program to get the right placement. 4) Export the edited obj(s). 5) Inject the edited hair obj(s) into the hair yobj with ReShape or X-Rey. 6) Extract the hair textures and add them to your main character’s 000A texture pac. 7) Inject the 2580, edited 2715, and edited 000A into your PACH/SDHC.
Disabling Facial Animations
Because your face will wig out unless you create the individual facial animations
1) Open the decompressed 0000.yobj of your character in hex. 2) Search for the string “BrowInn_L_Dn” (this will be position A). 3) Search for the string “fixNarrowJawDnR” or similar (this will be position B). NOTE: Some WWE 2K17 YOBJs have a more data after this point that needs to be zeroed. 4) Select the data from position A to B (the size in this case is 000006DF). 5) Fill the selection with 00s (in hex). 6) Save your file with the hex editor.
Modifying Character Textures
Character textures are contained in two files within the character PC:
- 000A = Main attire, hair, eye textures and all map textures (ao, normal, etc) - 000C = Main face and body textures
These textures are in .dds format. Main textures will have DXT1 compression, and Normal Maps will have DXT5 compression.
Textures can be edited in photo editing programs like Photoshop and GIMP as long as a DDS plugin is installed.
NOTE: Remember to also edit the map textures (ao, normals, etc), or else your character will have bumpy or shadowed outlines of the original textures.
Dealing With 2K18 TX Pacs
Many 2K18 characters don't actually include the textures in their ch pacs. They are contained in TX files and are often shared between characters. They include a file called 14.onet. If you open that file in hxd (hex editor) you will find that a number is listed and then the dds file name then repeat.
In the pac\ch folder, there are a series of tx files. The textures are in these files. You have to use the 14.onet to find out where the textures are (ex: if a head.dds for Roman is listed as 36802, Roman’s Head is in tx36802 but the shoes.dds may be listed as 36702 so the shoes are in tx36702).
The best procedure is to NOT edit the tx files, but just extract them and build traditional 000A and 000C files, and then build your own pach as you would have in 2K16 or 2K17.
Creating Normals in Photoshop
1) Create your main image. 2) Use NVIDIA Tools plugins to generate normals. 3) Adjust the brightness of the alpha layer to add/remove shine (brighter is shinier).
Creating Normals in GIMP
1) Download and install The GIMP normalmap plugin. 2) Create your main image. 3) Go to Filters > Map > normalmap and run the plugin. 4) Adjust Scale/Alpha Channel/Invert options to replicate the effects of the default normals. 5) Adjust layer transparency if needed.
WTF Are Mips?
You may have heard mention of "mips", or "mipmaps", so what are they? The short answer: a pain in the ass. Most of the DDS files ingame have mipmaps. Mipmaps are essentially hidden layers which are smaller resolution versions of the main texture. If you use GIMP these layers are viewable in the layers pane. In Visual Studio there is a drop-down menu in the side bar for them. The number of mips varies depending on the size of the texture. Larger textures generally have more mips.
If you change the main texture, but not the mips then your change won't show up in-game, because the full resolution texture is rarely used.
So how do you deal with them? There are two ways to deal with mips. The first is to generate new mips with whatever DDS plugin/export settings you are using. This is generally done when exporting, although Visual Studio has a separate drop down tools menu for this option which must be done before exporting.
The better way to do this is to save your textures without mips, and make new texture archives (because the file size will be different in the mip-less file meaning you won't be able to inject back in). This will mean the game uses the full resolution texture and things will be clearer in-game. Your file sizes will also be smaller, which can help get your mod under the 80mb limit.
Side Note: There are also things called "frames". Frames are essentially color swapped versions of the same texture. Each frame has it's own set of mips. Frames can be seen as a drop-down menu in the side bar when using Visual Studio. The only known textures that use frames are the crowd member textures (arcrowd##.pac).
If you apply a transparency shader to an object in something like X-Rey, then you can modify the alpha of your normal file (black and white) to make certain parts of the object transparent or semi-transparent.
This can be helpful, for example, if you would like to "remove" part of an object such as making the sleeves of a jacket invisible.
Frequently Asked Questions
I added/removed parts to my mod, but now the character has holes in him?
Zero out and reinject the uncompressed 00CE file.
I added a mod and now my game crashes on boot?
Zero out the two bin cache files in your game directory.
I created a mod with a bunch of added parts, but it crashes in-game?
I injected everything as ZLIB but the mod still crashes?
I’m hopeless, my mod still crashes. Please help euthanize me!
Calm down, no need to jump off a bridge. Rebuild your pach bit by bit to isolate the issue. Something may have been injected wrong or you may have a corrupt texture or object causing the crash.
I’m trying to unrender with Anatomizer, but it can’t move objects or change render count?
Try making a copy of the yobj file and opening the copy with Anatomizer.
I edited my textures but they didn’t change in-game?
Did you remember to either save without mips or generate new mipmaps? SPOILER: You probably didn’t.
I edited my textures but I can still see bumpy outlines of the previous textures?
You forgot to edit the normals silly. Now go act normal so we don’t notice you’re a freak.
I’m trying to inject textures, but it says I have the incorrect file size?
If you remove mips, change texture size, or compress differently you can’t inject back in. Try creating a new texture pac instead.
Can I use last gen objects in my mod?
Short answer, likely not, but possibly depending on the object. For faces you may also use is as a form for shrinkwrapping.
Errrrrmahhhgod what DDS type should I use? DXT1? DXT5? DXT10? I just don’t know!
Open your DDS file in hex. The header will tell you what type the default is. Things with alpha channels like normals usually use DXT5. Main textures are usually DXT1. Menu items are typically DXT10 although DXT5 usually works as a replacement.
A WWE 2K15 tutorial told me to inject new parts into the 4E22 slot. But it’s not working?
I disabled animations but my head is still doing it’s best clayface impression?
Some of the newer models have a bit extra animation data at the end of the usual section. That needs to be zeroed out as well.
Can I use CAW parts on my mod?
If you figure it out let us know. The top minds at NASA haven’t found a way to do it yet.
Why won’t my mod show up in CAS?
Probably because you have added parts. Mods with added parts will crash CAS.
I added a beard using an added yobj, but it doesn’t show in-game?
The beards are attached to the “beard” bone in their heads in WWE 2K17 and WWE 2K18. Without the head, the bone is unrendered, this the beard is as well. Keep the head in the added yobj, but shrink it to hide inside your main head. This also applies to some masks and piercings.0
I’m trying to add parts but they keep spazzing out in game?
How do I open texture files?
Your favorite image editor. You may need to an additional DDS Plugin. There is company from Mountain View that can help with that.
