I'm trying to edit the .json file for emeralds so I can have a texture pack that enlarges my custom texture. I've looked around for tutorials but can't find any simple ones I understand. This pack is for 1.8.9 on Java edition. Here is what I have taken from another texture pack but it doesn't work for my textures.
Thank you so much for replying, sorry about the wrong classification, I'm just starting to make these packs. I'm trying to get the emerald to be bigger on the ground when you look at it. I saw this in Wallibear's videos with his diamond resource pack. right now I have this in a .json file in assets/minecraft/models/items. But when I go onto Lunar client and throw the item on the ground, the size doesn't change, I'm wondering if someone with more experience can tell me what's wrong.
I just assumed that the reason it wasn't working was that the parent tag thingy (that I can't seem to understand) is using the wrong texture.
