• Or, you can also use Steam to navigate to the workshop.

• You can also subscribe to items from the thumbnail view, by hovering over and clicking the green plus button on the bottom right corner of each thumbnail:

• Click on ">>> Refresh <<<" periodically until all items have finished downloading.
  
• Download progress can be monitored in Steam (Library > Downloads).
  
• Workshop skins will have a blue name in-game if selected.
  
• You can still use local skins as usual, nothing has changed.
  
• Once a workshop skin is downloaded and selected, it will continue working even if Steam is not running:
  
• However, if Steam is not running, then you may not switch workshop skins.
  
• And, if Steam is not running, then switching to a local skin is not undo-able.

(Note that there are differences between the official osu! client and McOsu, but almost everything is supported and just works.)

This guide assumes you know what the folder structure looks like.



/<Steam>/steamapps/common/McOsu/materials/default/

To get to this folder, right click on the game in your Steam Library > Properties > LOCAL FILES > BROWSE LOCAL FILES:

• backgroundcube
  
• cursor-ripple
  
• loading-spinner
  
• seektriangle
  
• skybox
  
• slidergradient
  
• songselect-top
  
• songselect-bottom
  
• user-icon

This guide assumes you know what the folder structure looks like.

Your osu!folder MUST be an absolute path[en.wikipedia.org]. Relative paths will NOT work.
(If you never deliberately entered a relative path then everything should be good.)

Here is an example:

• Use Photoshop / GIMP / Paint / whatever your favorite image editing software is.
  
• Filesize must be less than 1 MB
  
• Format must be JPEG
  
• Filename must be steamworkshopthumbnail.jpg

Here is an example folder/file structure:






Go to Options > Skin:



Click on "Local Skin ..." and select the local skin you want to upload/update:

• Notice how the skin name changed from blue to white once a local skin was selected.
  
• Only continue if the game successfully loaded your local skin as usual.

osu_workshop_upload_skin

• By submitting an item, you agree to the workshop terms of service.

• (Look for error messages either on the top left of the window (console log), or as notifications.)

• If you did everything correctly, a loading spinner will appear in the middle of the screen.
  
• After the upload is finished, the newly created workshop page for your item will be opened:
  
• There you can change the name, description, add screenshots, etc.

---

• After a successful upload, a new text file containing the item ID will be added to your local skin.
  
• This text file uniquely identifies your workshop item, and allows you to update it later on:
  
• steamworkshopitemid.txt

By default, all uploaded items have their visibility set to private (to allow editing name/description/screenshots/etc. before going public):



Navigate to the Steam Workshop for McOsu, select your item, and change its visibility via the owner controls:
