Java: Export Vanilla Models

IMPORTANT:
-Any missing folders need to be created if they aren't there yet!
-Do the steps in this exact order!

Step 0: Setup
**-In Blockbench: **
Use the Java Block/Item format. (Check at File > Project... in Blockbench).
If it's not convert it via File > Convert Project. ATTENTION: This can break the model due to format specific restrictions! (see !faq java-rotation and !faq java-sizelimit)

-Setting up your pack:
Create a folder inside Minecraft's resource pack folder (aka "YourPack" for the rest of this guide). It is usually at C:\Users\INSERT_YOUR_PC_USER_HERE\AppData\Roaming\.minecraft\resourcepacks. Put this file https://cdn.discordapp.com/attachments/883449189533638777/899224109869846558/pack.mcmeta in YourPack.
Optionally: Edit it in a text editor and adjust the value of "pack_format" (see https://minecraft.fandom.com/wiki/Pack_format). This only affects whether your pack is shown as "outdated" ingame or not.

Step 1: Saving Textures
Save all your textures first.
To do that either:
-Ctrl+S, or
-click 💾 next to the texture(s), or
-rightclick the texture(s) and click "Save As"
Save them directly within YourPack/assets/minecraft/textures/block/... or /item/....
Reason: If you don't do that or move/rename the files later your model won't find the textures anymore.
(For custom subfolders check !faq java-1.19.3-textures)

Don't use capital letters nor spaces in file/folder names. The model will be invalid ingame!.

Step 2: Exporting the Model
After saving the textures use File > Export > Block/Item export it to YourPack/assets/minecraft/models/item (or /block, but only for placed down blocks.).
Name the file based on the id of the thing you wanna replace (totem_of_undying for a Totem of Undying for example). Check the default pack if you are not sure what the exact name is (see !faq default-pack for more information)

FAQ

Java: Armor

The armor model when worn on players/entities cannot be remodeled in vanilla Java edition, only retextured. Pumpkins and other items set on a player's head can be remodeled for custom hats, but won't display if set on feet/legs/torso.
(Any item can be put on the players head via the /item replace command (aka /replaceitem before 1.18), or ofc via mod or plugin methods).
Furthermore, with this pack you can give a large set of specific leather armor colors a unique texture without interfering with the colors available in a normal survival situation: https://github.com/Ancientkingg/fancyPants

With Optifine it is possible to add texture variants on any armor pieces depending on the name, damage and other nbt, but remodelling is also not possible with it.

[civic pine]

you can make armor textures different in vanilla but not based on custom model data

so like if you retexture diamond armor then every single diamond armor set will be retextured

you could do some stuff with custom trim textures though

[sharp onyx]

what about if i dont put armor on their head, but rather something else? would that still work?
