Hey @Divone!
You should be able to migrate them from an existing template project of yours.
To migrate, you can right click on an asset, then hover over the Asset Actions section on the menu that pops up, and select the Migrate option on the sub-menu. It’ll automatically include all the dependencies but you can also adjust the selections if you don’t want the textures for example, then hit OK while making sure to keep all the necessities, and finally select the Content folder of the project you wanna migrate them to.
You can also right click on a folder as a whole in which case the migrate option won’t be hidden under any additional menus when you right click.
Hope this helps!
