HMCCosmetics is a conversion target only. You can convert to HMCCosmetics from any other source, but not from it.

Vanilla works both ways: convert a plugin config down to a no-plugin Vanilla resource pack, or bring a Vanilla item-model setup into a plugin. Because a Vanilla pack is a full resource pack + datapack, Vanilla conversions run in the converter’s Project mode (a full pack archive), not the single-file YAML flow. Want to build Vanilla from scratch instead? Use the Vanilla Resource Pack generator.

Multi-target conversion targets plugin formats; Vanilla isn’t available as a multi-target output. Convert to Vanilla on its own in Project mode.

Convertible Features

The converter recognizes and handles the following feature types across plugins:

Feature	Description
2D Sprites	Flat textured items
3D Models	Items with custom JSON models
Custom Model Data	CMD value mapping
Hats	Wearable head items
Armor & Armor Trims	Armor sets and trim support
Equipment	Equipment slot configurations
Blocks	Custom placeable blocks
Furniture	Decorative placed models
Bows & Crossbows	Ranged weapons with pull animations
Shields	Custom shield designs
Tridents	Throwable weapons
Food	Consumable items with effects
Fonts & Emojis	Custom font images and glyphs
Recipes	Crafting, shapeless and cooking recipes
Lore & Enchantments	Item descriptions and enchantment data
Attributes & Durability	Custom stats and durability values
Permission nodes	Carried over where the target supports them

Not every feature has a 1:1 equivalent across every plugin. When something can’t be fully mapped, the converter keeps your data where it can and shows a warning with a suggestion instead of dropping it silently. See Known Limitations.

HMCCosmetics Options

When converting to HMCCosmetics, additional options appear:

Default Slot — HELMET, BACKPACK, CHESTPLATE, LEGGINGS, BOOTS, OFFHAND, or BALLOON
Dyeable — toggle whether the cosmetic supports color dyeing

Popular Migration Paths

ItemsAdder → Nexo

The most common migration. Nexo is the modern successor to Oraxen and many servers are switching to it.

Oraxen → Nexo

Direct path since Nexo inherits many concepts from Oraxen.

ItemsAdder → CraftEngine

For servers adopting CraftEngine’s modern approach to custom items.

Any → Vanilla

Drop the plugin dependency entirely and ship your items as a pure resource pack.

Any → HMCCosmetics

Offer your custom items as wearable cosmetics with slot-based equipment.
