Chest texture won't work, tell me how :/

Please tell us exactly whats your problem.
Putting a texture on it?

I put a texture, activated it, but still didn't show in-game

Alright.
If you put art on the texture, it should work.
What you can do is :
-Check if your game graphics are set >Minumum
-Wait for the texture to load once you get in-game

Note that black colors of the texture might appear white in-game.
Kinda how transparent sets are made.

well, thanks
