1.11.6

Yeah 2 updates in 1 day....

This update adds support for CustomModelData via the new config option for items: nbt_int: <key>:<value>

example:
This allows you to use your custom models within your texture packs to show new items that aren't provided by Minecraft but rather new models provided by your resource packs.
Here is an example of a green sword that is added with CustomModelData:


This update also allows specifying other NBT data although it might be a rare case it is used:

Hope this allows more customization with your menus and especially anyone who uses CustomModelData in resource packs!
