I tried making a custom item texture based on the durability of an item but every time I equip the texture pack, the black and purple box keeps showing. I was wondering if the code copying and pasting into the .json file might be outdated(I'm using 1.16.5.) Here is the code from assets\minecraft\models\item\stone_sword.json I put my custom texture(named zombie_sword) in assets\minecraft\textures\item. This is how the item shows up in-game with the texture pack on As you can see it is on 1 durability like it should be but the texture is not right. It is a stone sword btw I just renamed it.
