Component Based (1.21.2+)

If using COMPONENTS as your custom-armor type, you are not limited in any way, unlike TRIMS & SHADER. Unlike SHADER this method does not break with shader-mods and is not restricted to LEATHER_ARMOR items. It also has the benefit of not needing to be based on an armor-item at all, use PAPER if you want to. Every downside there has been to earlier methods is now gone, no restrictions.

How to configure your armor?

Make sure that the itemID of your OraxenItem follows the pattern armorname_armortype. For the rest of the above set it would be ruby_chestplate, ruby_leggings and ruby_boots.

Make sure your armor-layer files follow the format of armorname_armor_layer_1/2.png. In the example below, we would need a ruby_armor_layer_1.png & ruby_armor_layer_2.png

Simply set the material you want, no need to specify the texture-icon twice:

ruby_helmet:
  displayname: "<gradient:#FA7CBB:#F14658>Ruby Helmet"
  material: PAPER
  Pack:
    generate_model: true
    parent_model: "item/generated"
    textures:
      - default/armors/ruby_helmet

An Equippable-Component is also necessary for the armor to display correctly. Oraxen will automatically assign it if it has not been manually specified. You can optionally manually assign the component if you want to. The value should be oraxen:armorname, so in our example;

ruby_helmet:
  Components:
    equippable:
      slot: HEAD
      model: oraxen:ruby
