As of August 2022, Craftable Horse Armour will not be receiving any further updates.
Current Release: 1.18.2
Current Beta: 1.19-snapshot (supports 1.19)
This datapack adds saddle and horse armour recipes (Finally) along with adding a use for rotten flesh!
In the base game, you would have to go searching through a fair amount of structures to find both a saddle and either iron or diamond horse armour and with this pack installed, you'll gain access to crafting them instead of long-distance scavenging. Along with new recipes, you can turn rotten flesh from being useless into an easy for leather. Just use a furnace (Not a smoker or blast furnace) to cook rotten flesh and BANG! Leather.
Note
If you create a new world with this datapack, click the "Datapacks" button and insert the datapack and make sure it is active during creating your new world. If you intended to install this datapack into a existing world, (I highly recommend backing your world up - just in case), close the world, add the datapack, and then re-open it. ( /reload will not work)
This datapack supports Minecraft Java Edition
