OK so i finally got with times to see if i can appreciate Umin and friend's work on the modloader and damn they hit the spot.

This tool let's modders create new slots and lets players use them which is especially helpful if you happen to be a mod junkie and want every mod that you have available for use.

Afaik there isn't a way to transfer existing mods to this new system without a full rebuild or assistance from the OC but that's fine by me.

At the time of this guide, Umin has information on setup on the ModdingZaibatsu discord server and on TekkenMods.com. The links are to his Github where he is maintaining the newest releases. This guide was written so I don't forget what to do and to be a backup in case something happens to the existing resources. I am only a lowly user of this tool so all credit goes to Umin and those he worked with.

EVERYONE

Step 1: Install the ModLoader link

  1. I wasn't able to get chrome to download Polaris_TKDataLoader_0.802.zip so I downloaded PolarisModLoader_Installer.exe instead which is what I would recommend.

  2. Download this file wherever you want to then run it. Verify the file path is to your Tekken 8 folder (ex. ...steam\steamapps\common\TEKKEN 8). then Install.

  3. If you don't see PolarisTkdataModLoader.asi in your ...steam\steamapps\common\TEKKEN 8\Polaris\Binaries\Win64 folder then it's likely being blocked by your antivirus and you will need to create an exclusion of the ...Win64 folder to prevent it from deleting it. Run the program again and Re-Install.

  4. You can also verify that it works by loading Tekken 8 and hitting ctl+P to open the UI.

Step 2: Load a tkdata ready mod.

  1. Download the mod as usual for any regular mod and put it in your "mods" folder...any name is usually fine as long as it is not "~mods" which is primarily only used for audio mods. This is the mod made up of the 3 mod files (.pak, .utoc, .ucas).

  2. There will be a file ending with *.tkmod. place this in ...\steamapps\common\TEKKEN 8\Polaris\Content\Binary\Mods\tkmod*.tkmod. This is necessary for the mod to actually be seen and loaded into the game.

Step 3: Turn on Tekken 8 and enjoy.

  1. If you want to do a little more with the tool then check out the next section aimed towards modders.

  2. When you get to customization you should see a brand new slot and not just a replacement of an existing one.

MODDERS

Step 4: Create a tkmod ready mod in UE.

  1. Create the mod the same as you would do any other mod but now you create a fully custom IP with a unique name instead of naming it after an in-game IP.
  2. The new IP will need to use the Tekken 8 placements in order for it to load. For example: an IP called IP_wild_armpit_hair_sweater is an upper body item for Kunimitsu so it will need to go into Content/Character/Item/Item_Prefab/bdu/IP_wild_armpit_hair_sweater.
  3. That's pretty much it. There's a list of all the original info.. link thanks to Umin in case you need it or want to reference it.

Step 5: Install PolarisTKDataEditor link

  1. Download and place where ever you want to.

Step 6: Create the *.tkmod file.

  1. Run the program and got to FBSDATA menu (left hand side of the most recent version) and hit "+Add" (on the upper far right).

  2. There are 2 categories to choose from.

tkdata > customize_item_common_list.bin / customize_item_exclusive_list.bin / customize_item_unique_list.bin. and

exception > customize_item_exception.

All I know is the customize_item_common_list.bin works fine and the customize_item_exception acts will essentially keep the selected IP from loading.

  1. Now it's time to edit the information in the created row. These are the key fields I work with:

a. Item ID: 000 - 999 (IMPORTANT: Duplicate IDs are no-no so avoid them and keep track.)

b. AssetName: The name of your IP ex. IP_wild_armpit_hair_sweater.

c. Character ID: Choose the character the mod is for. Ex. KER:Kunimitsu

d. ItemPosition ID: Choose the category. Ex. bdu: Upper Body

e. IsColorable: Make sure it's checked if your mod is built to be colorable already.

FOR NOW DON'T MESS WITH ANYTHING ELSE OR RISK MESSING THINGS UP FOR PPL THAT USE YOUR MODS.

  1. When you're done with your edits hit "Save".

  2. Name the file and put anywhere you want if you're just storing it or in the tkmods folder (see Step 2.2) if you will load it.

ADDITIONAL OPTIONS:

1. EDIT tkmod. You can simply use the "Load" button to load an existing .tkmod, make changes, then save a new one or overwrite an existing one. This is helpful if you come across an ID conflict and need to change the Item ID to resolve it. It's also a good option when you decide to rename an IP or use a different one.

2. MORE STUFF. I'm not gonna lie, this is all i'm here for but explore Umin's github for more info and to see the full potential of this tool. Just don't come asking me about it.
