📦Inventory Texture

If you already finished the creation of your custom things and the custom mappings you can continue following this part

---

To start go to your resource pack in this path MyAmazingResourcePack/textures and create a new file named item_texture.json.

Inside the file put this next code

{
  "resource_pack_name": "im a resource pack",
  "texture_name": "atlas.items",
  "texture_data": {
    "name_of_your_custom_thing": {
      "textures": "textures/items/im_a_texture"
    }
  }
}

With this code we are selecting which texture we are going to use in the item for the inventory display. So lets fill it, in "resource_pack_name": "" we put any name of our preference, this don't need to match with the name in the manifest.json

{
  "resource_pack_name": "Im a beautiful resource pack",
  "texture_name": "atlas.items",
  "texture_data": {
    "name_of_your_custom_thing": {
      "textures": "textures/items/im_a_texture"
    }
  }
}

Then we are going to define the texture, first you need to put the identifier of your item without geyser_custom:. To avoid problems make the identifier the same name as the texture, in Minecraft Java put the identifier name as the texture name too.

{
  "resource_pack_name": "Im a beautiful resource pack",
  "texture_name": "atlas.items",
  "texture_data": {
    "ice_helmet": {
      "textures": "textures/items/ice_helmet"
    }
  }
}

Here don't matter if you are making a item/armor or what ever because you are only saying the textue on the inventory

To define more than 1 texture you can add a coma and put the same format, like this:

{
    "resource_pack_name": "Im a beautiful resource pack",
    "texture_name": "atlas.items",
    "texture_data": {
        "ice_helmet": {
            "textures": "textures/items/ice_helmet"
        },
        "ice_chestplate": {
            "textures": "textures/items/ice_chestplate"
        },
        "ice_leggings": {
            "textures": "textures/items/ice_leggings"
        },
        "ice_boots": {
            "textures": "textures/items/boots"
        }
    }
}

With this you are done with the textures, you can continue with the next
