@Bloo: It shouldn't have any objects as you already have them in game. what it should have is a .object file that you need to put in FeralHeart>Media>Objects and then open up your game and find it in Object Maker. There you can transfer the objects into your own folders if needed.
Kaylee: I do enjoy Zelda but I believe there are already Zelda things out there somewhere in the community that include chests and such. I am not sure where they are but you might check Jayfeathers stuff, and Gailous stuff, both of them have some Zelda or Zeldaish items. I make original items, not so much items you find in other games.
