How to include Spun/Nix rocks with my Map?

I downloaded and made use of Spun/Nix' rock pack in a map and published privately to the workshop but then when I subscribed to it I got errors on loading which persisted until I manually copied the rock meshes to my Media folder for the game. Is there a way to publish dependent objects with my level so that people downloading my map won't encounter this problem?

You have to manually add them to your map folder prior to uploading to the workshop.

I had tried dragging and dropping in the editor and that didn't work. Do I have to do that in Windows Explorer or some other way?

Thanks!

@notgiven You add them to the (media) folder of you map. Just like you did for the game.

OK, I get it now. Thanks guys!
