Football Manager 2026 Skins - Diablo 26 Skin by (sic) v0.4.1 - incl. attribute-less version
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.


Notes


- 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.

- Unfortunately, there seem to be issues with Mac. To my understanding this is due to how the files are bundled or compiled on Windows vs Mac - and it's something completely out of my control at this moment. Some files will work, some won't.


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.

Updates

v.0.4.1 - Small tweaks to one of the attribute color presets.
- Removed certain files that were causing issues on Mac. Please note that the skin won't look 100% the same on Windows and Mac due to this.

v0.4 - Added multiple attribute preset color ranges, including a totally transparent one for everyone who likes to play attribute-less!
- Small tweaks to key/preferable attribute highlight.
- Small tweaks to table visuals.
- Separated Windows and Mac into 2 folders, to hopefully avoid any issues/crashes caused by one of the files on MACs.

v0.3 - Fixed the issue with player instructions not appearing.
- Added dark background option, without competition graphics.

v0.2 - Fixed the skin to work with the new update.


How to Install the Diablo Skin on FM 26


1. Extract the contents of the downloaded file.
You'll get 6 files inside the Windows folder:
  • ui-datacollections_assets_all.bundle
  • ui-preferences_assets_all.bundle
  • ui-styles_assets_common.bundle
  • ui-styles_assets_default.bundle
  • ui-tactics_assets_all.bundle
  • ui-widgets_assets_all.bundle
There will also be folder called "Backgrounds". Simply navigate to whichever option you prefer, and copy the ui-backgrounds_assets_common.bundle - file into the same folder as other files.

Mac folder will have a file less (ui-tactics_assets_all.bundle is not included as it seems to cause issues on Mac).


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!

    Superb Work, Quick question how do you turn on the show attribute changes in the game i cant see which players are improving unless i mentally remember their attributes i see on one of these screens Mbeumos Free kick taking has the green arrow next to it
  • Entreaty's avatar
    Unfortunately, as I mentioned - I am unable to accommodate everyone's requests. Everyone likes to use different colors for attributes, and there are only 4 presets.

    Regarding CA/PA - unfortunately, this is not something that I think is possible right now - or at least none of us have discovered how to do it yet.
  • Zen7198's avatar
    Can you set one preset attribute color as the default like in the original game?

  • RenKyuu's avatar
    Hello, are you going to inclure the player CA-PA ?
  • filipelh98's avatar
    Hi, on my Mac I replaced the original files with the 7 downloaded files. When I open the game, this message appears: "fm cannot be opened because it is damaged. This item should be moved to the Trash." What could I be doing wrong? tks
  • Entreaty's avatar
    Thanks everyone.

    There should be 4 attribute presets to choose from (one of them is completely invisible, so 3 really).

    Attribute color changer will not work here, so any color changes would have to be done manually by using UABEA - opening the bundle containing attribute colors (ui styles default), and changing color values.

    Everyone has their own color preferences, and SI have only put presets into the game - rather than letting us change colors from inside the game...

    @daveo72

    Hi, yes this appears to be a Mac issue. Unsure why it happens, but some users have narrowed it down to 2 files - ui widgets and ui tactics. You can try using the skin without those 2 files.
  • daveo72's avatar
    I'm having issues with the custom skins on Mac. There are currently 3 out there so this could be user error but I'm following the guide. When I install the files and start the game initially it looks ok however the load game button is blank. Then in game all the top menu tabs show as 'ITEM' and there is no drop downs available. Is this an issue with Mac's?
  • Entreaty's avatar
    Thanks everyone.

    @Manager34 - you can, but only the default preset is "finished" - I will post an update today that fixes the other 3 presets as well.

    @Saran1991 - are you using the new beta release? If not, then you might need to wait for the patch to officially drop.

    @dosh - thanks - yes, something like that is planned - I will post a few versions of the BG.

    @luckyluke26 - Thanks. I'm not exactly sure what exactly that is, and if I haven't noticed it yet - I probably am not going to update it any time soon :D
