[1.12.2] Overlaying Item On Top of Item

[unassigned]

Hello. I have an item that has an nbt stored of an item that was used in crafting, however, as all the items are the same, there is no actual identifier other than the tooltip (and nbt stored to the item). So I was wondering if I could overlay that item used in crafting on top of the item itself, as in if it used a diamond in crafting, it would overlay the diamond on top of the icon in the inventory. This would prevent me from making hundreds of textures for the item, as well as give way better mod compatibility. I'm just not sure how to go around doing this. 

 

Thanks.

You want a custom baked model implementation.

TheGreyGhost has one in MineraftByExample at https://github.com/TheGreyGhost/MinecraftByExample, however the code is a bit outdated. You should read
