Update 07.04.2026:

Update to version 5.1

For updates and further information, please check here

 

 

 

To install the skin, do this:

 

  • Download the bundles archive
  • Locate your game directory. For steam this will usually be:
    \Steam\steamapps\common\Football Manager 26\fm_Data\StreamingAssets\aa\StandaloneWindows64\
  • For Gamepass installations it should be
    \XboxGames\Football Manager 26\Content\fm_Data\StreamingAssets\aa\StandaloneWindows64\
  • Make sure you have an unmodded Game, as you will otherwise create an unhealthy mix of modded files and those from this skin
  • In case you're unsure, verify your gamefiles first!
  • Copy and paste the files form the skin archive into the above game directory. When asked, choose to overwrite/replace the existing files.

 

The mirror links will now directly point to the Skinbuilder site - where you can download them and directly manage the Skin (including easy updates!) in the tool.

For some quick guidance, you might want to check here.

Is it possible to get both.  I like the ability to make personal changes using the skin builder

 

I have no plans to drop the sharing of my skin as Skin Builder skin. 

 

However, as the tool gets more and more powerful and complex - it might easily overwhelm a lot of users, so currently I lean towards publishing both in future.

At least the base version, my blue theme, might be available as bundlepackage, while I continue to share the full version with the three base colors and potentially easy replacement of Teampictures as well.

brother hi, I'm working on a modification that limits the polygon and attributes features, but I can't figure out where the polygon in the overview of the player comparison screen comes from. Do you know where it is?

Version 2.5 is ready for release.

 

It will come with many small enhancements (dividers are back visually), new fonts and a new Portal Overview:

As annoucned already, it will contain easy color switching through config mapping. I will wait for the patch announced by SI for tomoorw and verify if all works as expected. Once that is verified, the update will be released.

 

As usual I will release it as Skin Builder skin, though I have realized that a lot of users might have issues working with the tool. For all those, I will release the blue base version as bundlefiles as well. Hope it helps those, struggling with the tool…

Dear @Darkside63

here he is again. The German skin creator king. 🙂

It's really great what you're doing. I'm very happy that you're putting a lot of time and effort into fm26 as well. Thank you. Unfortunately, I don't have the fm26 game, but, we will see.

 

Edit: you include Adboard Changes? you know this?  = @Dale Niland 

Link: https://sortitoutsi.net/content/75422/static-adboards-for-english-premier-league-and-the-championship?page=2
maybe you can work with him together, so just one mod needs, for having real adboards in the 3d match + your Skin.
Example: the download Link A is your Skin and the Addon Link B is for including real Adboards

This looks really cool.  I've just purchased FM26 after a long hiatus from the game.  Using "skins" seems a lot more complicated now.  I like the coloring of the Alex Morat skin yesterday, but the latest update killed that.  It doesn't appear that skin will continue so I need to move on.  This one looks great and it appears that I can mimic his color pattern and get some other enhancements too.  Is that possible?  I'll need to review the instructions and make sure I get this right.  It seems a bit complicated for me.  Any tips for anyone new-ish?

Glad you like it.

 

In general, sure it's doable. Most colors or classes which are in the skin are commented, so you get an idea what they actually do…. It's a tray & error approach tbh.

The best suggestion might be - onyl change one thing at a time and see what it does…

I updated the new skin with the new version of th Skin Builder and with the new game patch, but it keeps crashing with an ‘application error’ (screenshot below) a couple of minutes into the game : (

 

Already tried restoring game files and building again but no luck.

 

Any suggestions?

Try this:
 

  • repair your gamefiles 
  • check into your users windows homedir -→ AppData -→ Roaming -→ io.fm.skinbuilder -→ backups
  • delete the folder “originals” and the two files in there
  • redo your build & apply

Working great so far, top man!

 

To change the background, can I just swap it for one of the same size with the ‘11’.jpg in the Base Picture Set file? Last question I promise ; )

Yes. As long as you go with the same size - you should be fine

@Darkside63 Well done mate, this is the best one so far. Would love to get into this and do a West Ham one when I get more knowledgeable on how to create these in skin builder

You will get into that mate… In the beginning it's some learning curve, but when you start slowly and doing it step-by-step, you will get a feel for it… For what you doing in your thread, Skin Builder would be a blessing for you. You would just need to create the pictures as you do, put them in the proper folder and adjust the mapping. Skin Builder will create the proper bundelfile(s) for you… It's worth a try ;-)

Thanks mate, I'll keep trying. Love that you put both the skin builder file and the one that goes straight into the standalone folder. Gives me some guidance on where things go. I'm going to give the skin builder a good go at the weekend when I've got more time

@Darkside63 I seem to be getting a shut down error using the Darkside - Base 2.5 Release theme via the skin builder. Game seems to run fine unless I click on a player name to look at the player. Then my game closes instantly so not sure what I'm doing wrong. I'm loading the skin in the builder, all I've done is change the colour to the club colour then run it through the builder, I then apply in game. Not made any amendments to the skin at all

It might be an issue based on the 0.5.0-4 Beta…

 

  • Make sure you have the current Beta 0.5.0-5 of Skin Builder
  • Restore your gamefile to “Original”
  • Go into the settings in Skin Builder and delete the backup files
  • Repair your game installation via Steam/Gamepass
  • Rebuild and Apply your skin

 

Issues might be fixed…  I can not reproduce the error but could image what might have happened.

 

Also ALWAYS make sure you only apply a skin via Skinbuilder if your gamefiles are original! Everything else will lead to an unhealthy mix and problems…

Use skinbuilder version and just deselect "fonts" in mapping

I did that, however font still changed, for whatever reason. Maybe it's due to other than english language of the game?

Oh, you did?

 

Ok, do the follwoing…

 

  • restore Original Gamefiles
  • goto “packages” folder within the skinbuilder skin
  • delete the two “ui-fonts*” bundlefiles
  • Apply your build again

 

Should fix it…
