Football Manager 2026 Skins - Diablo 26 Skin by (sic) v0.1
From the creator of Livid skins for previous FMs, the new Diablo 26 skin brings back the sleek dark theme - this time with red accents!

Currently, this is more of a custom theme than an actual skin with custom panels.
Together with people over at SI Forums and Discord, we managed to figure out how to change various colours, backgrounds, etc. Some of it was easier, some of it was difficult to find - but at this moment, I feel this first version of the skin is ready to be released!

With time, there will be updates - this is the earliest version of the skin.
There are many talented people in the modding community working hard to make this process easier for everyone - so I'm confident that very soon there will be more possibilities in terms of modding.

Please note that this skin is primarily made for personal use. I understand everyone has different preferences, in regards to backgrounds, colors used, etc.
I will look to help out as much as I can, but please understand I can't accommodate everyone's preferences.

Please also note that currently, some UI mods might not work together - if they replace the same file. This will most probably be changed soon with custom mods.


Backgrounds

Currently, the skin has overlays dependent on the competition you are in - just like the default game.
If you want to have the same default background, without these overlays, I will post a file here that you will need to replace.
Coming soon.

Additional Features

Currently, this skin includes custom attribute colors, with custom attribute ranges.

How to Install the Diablo Skin on FM 26


1. Extract the contents of the downloaded file. You'll get 6 files:
  • ui-backgrounds_assets_common.bundle
  • ui-datacollections_assets_all.bundle
  • ui-styles_assets_common.bundle
  • ui-styles_assets_default.bundle
  • ui-tactics_assets_all.bundle
  • ui-widgets_assets_all.bundle

2. Locate the Game Directory: Navigate to your Football Manager installation directory.
The standard path for Windows is typically:
\Steam\steamapps\common\Football Manager 26\fm_Data\StreamingAssets\aa\StandaloneWindows64\
And for Mac:
~/Library/Application Support/Steam/steamapps/common/Football Manager 26/fm.app/Contents/Resources/Data/StreamingAssets/aa/StandaloneOSX

3. Locate the original files (SEE ABOVE) in the game's data folder and make a backup copy before proceeding.

4. Copy and paste the files into the game directory. When asked, choose to overwrite/replace the existing files.

5. Enjoy!

    Hi. Thank you.

    Unfortunately, this won't work if you use a third-party tool to change colors.

    Currently, the way "skins" work, is that they replace entire .bundle files. These bundles contain several different files inside, but right now third-party tools (like attribute color picker) cannot replace only 1 file inside (let alone a line of code) - instead they replace the entire bundle.

    These tools also either use their own custom naming for each attribute color, or they use certain colors that already exist in the game - both of which are different to the way it works on my end.


    As I have mentioned in the post, some UI mods might not work together. We are still in very early stages of customization and modding.

    Hello
    Lovely skin
    One question though
    Why cant I change the attribute colors?
    When I use my own they just go white

    This is what I was talking about in regards to backgrounds. Everyone has their preferences, so I will be looking to add more versions (possibly one for each colour style to match with the club you're managing). Unfortunately, we are still some way off from having an in-game background changer.

    @Proton6 i saw that also...I hoped i could put a Feyenoord background or something like that in the game but i guess i can't till the full game is released.
