You can share compositions within editor.
Step 1. Store your composition: Step 2: Export your composition by clicking “Share Game”: Step 3: Everyone can find your composition by clicking “Downloaded” and “Get Compositions”:
In case you want a video, @spiritchaser28 made one for opening exploration maps in editor and storing compositions (not exporting them, though):  

  If you want to use the files instead: For the Steam version of the game, the files are located in: C:\Program Files (x86)\Steam\userdata\ (your user number) \298610\remote\Compositions and C:\Program Files (x86)\Steam\userdata\ (your user number) \298610\remote\Blueprints For the Microsoft version, they are within a folder in:
C:\Users\ (the user name that installed Ylands) \AppData\Local\Packages\BohemiaInteractivea.s.Ylands_ezkh2j9f9meea\LocalState\LocalPersistentStorage\Account\ You can copy and send the files to your friends and they can put them in the correct folder to be able to use them within the game.
