With the new snapshot for 1.19.4 and the armor trims announcement, I tried making a custom datapack adding more trims. This is a datapack & resource pack that aim to add more patterns and materials!

CURRENTLY IT HAS:

• PRISMARINE CRYSTALS material
• TRIFORCE pattern

TO DO:

• Make the language file

In-game COMMAND to get a custom netherite armor with the triforce pattern & prismarine material (feel free to edit the command with your selected pattern):

/give @s minecraft:netherite_helmet{Trim:{material:"cat:prismarine",pattern:"cat:triforce"}}
/give @s minecraft:netherite_chestplate{Trim:{material:"cat:prismarine",pattern:"cat:triforce"}}
/give @s minecraft:netherite_leggings{Trim:{material:"cat:prismarine",pattern:"cat:triforce"}}
/give @s minecraft:netherite_boots{Trim:{material:"cat:prismarine",pattern:"cat:triforce"}}
