This was made for snapshot version and since then, changes have occurs. It would need an update

figured out how to fix it! go to models/item and copy and paste spyglass.json and then change the copy to "spyglass_in_hand.json" I wanted to use this so bad I fixed it myself XD if you want it for 1.18 change the pack format in pack.meta to 8

edit: To the owner of the camera if you get the time you could do this to so you can update this to 1.18 :D

Should not be that hard to fix. I'll look into it when I have some time
