I'm working on a sword, that's supposed to look big. I want to do it with 2 textures. Thex 16x16 texture appears in the inventory just like normal swords. But when I hold it, it will use the 32x32 texture. It won't decrease it's size, like resource packs, but look as normal textures. How can I do this?
I saw this in a 1.7.10 mod, called the Lord of the Rings mod, just I'd like to do it in 1.12.2.
On the 3 images you can see how would it look in inventory, in F5 and in hand.
