Ultimate Custom Gear

Ultimate Custom Gear is a data-driven NeoForge mod for Minecraft 1.21.1 that allows server owners, modpack creators, and players to add fully custom armor sets, weapons, and tools — all through simple JSON files. No coding required.

Features

Add custom armor sets with per-piece defense, durability, toughness, and knockback resistance
Add custom weapons and tool sets (sword, pickaxe, axe, shovel, hoe) with custom damage, speed, and mining speed
Per-piece armor effects (e.g., helmet gives Night Vision when worn individually)
Set bonus effects when wearing the full armor set
Held effects per tool (e.g., pickaxe gives Haste, sword gives Strength)
Full multi-language support — define the full item name per language with no format restrictions
Custom textures with a flexible path system, or reuse textures from other mods
JSON files can be organized in any subfolder structure inside .minecraft/customgear/
Compatible with JEI
All items are enchantable with vanilla and modded enchantments
/customgear reload command to reload names, textures, and effects without restarting

Installation

Download and install NeoForge 1.21.1
Place customgear-1.0.0.jar in your mods/ folder
Launch the game once to generate the customgear/ folder inside .minecraft/
Add your JSON files to .minecraft/customgear/
Restart the game

JSON File Structure

All JSON files go inside .minecraft/customgear/. Each file defines one armor set or one tool set. Files can be organized in any subfolder structure you prefer.

Texture Fields

Field	Type	Description
`texture.mode`	String	`default`, `custom`, or `reference`
`texture.refs`	Map	Texture path per piece/tool. For `custom`: relative path from `.minecraft/customgear/`. For `reference`: resource location from another mod.
`texture.armor_layers`	Map	Layer textures for the armor model (`layer_1`, `layer_2`). Required for `custom` and `reference` modes. If omitted in `custom` mode, the JSON will be rejected with an error message. In `default` mode, this field is ignored.

Texture Modes

`default`

Uses iron armor/tool textures as placeholders. Good for testing.

"texture": {
  "mode": "default"
}

`custom`

Uses your own PNG files. All paths in refs and armor_layers are relative to .minecraft/customgear/.

For armor sets, you must provide:

armor_layers: Layer textures for the armor model
refs: Individual texture paths for each armor piece

"texture": {
  "mode": "custom",
  "armor_layers": {
    "layer_1": "models/my_armor/layer_1.png",
    "layer_2": "models/my_armor/layer_2.png"
  },
  "refs": {
    "helmet":     "item/armor/helmet.png",
    "chestplate": "item/armor/chestplate.png",
    "leggings":   "item/armor/leggings.png",
    "boots":      "item/armor/boots.png"
  }
}

For tool sets, one PNG per tool:

refs: Individual texture paths for each tool

"texture": {
  "mode": "custom",
  "refs": {
    "pickaxe": "item/tools/pickaxe.png",
    "axe":     "item/tools/axe.png",
    "shovel":  "item/tools/shovel.png",
    "hoe":     "item/tools/hoe.png",
    "sword":   "item/tools/sword.png"
  }
}

Example file structure:

├── models/

│       └── layer_2.png

        └── tool2.json

JSON files can be placed in any subfolder — CustomGear scans all subfolders automatically.

`reference`

Reuses textures from another installed mod. All refs must use the full resource location (modid:path/to/texture).

For tool sets:

"texture": {
  "mode": "reference",
  "refs": {
    "pickaxe": "othermod:item/mytool/pickaxe",
    "axe":     "othermod:item/mytool/axe",
    "shovel":  "othermod:item/mytool/shovel",
    "hoe":     "othermod:item/mytool/hoe",
    "sword":   "othermod:item/mytool/sword"
  }
}

For armor sets:

"texture": {
  "mode": "reference",
  "refs": {
    "helmet":     "othermod:item/myarmor/helmet",
    "chestplate": "othermod:item/myarmor/chestplate",
    "leggings":   "othermod:item/myarmor/leggings",
    "boots":      "othermod:item/myarmor/boots"
  },
  "armor_layers": {
    "layer_1": "othermod:textures/models/armor/myarmor_layer_1",
    "layer_2": "othermod:textures/models/armor/myarmor_layer_2"
  }
}

Note: To find the correct resource location for a texture from another mod, open the mod's .jar file (it's a ZIP) and navigate to assets/<modid>/textures/. The resource location follows the pattern modid:path/within/textures/folder without the .png extension for reference mode.

Effect IDs — Common Vanilla Effects

Effect	ID
Speed	`minecraft:speed`
Haste	`minecraft:haste`
Strength	`minecraft:strength`
Jump Boost	`minecraft:jump_boost`
Regeneration	`minecraft:regeneration`
Resistance	`minecraft:resistance`
Fire Resistance	`minecraft:fire_resistance`
Night Vision	`minecraft:night_vision`
Water Breathing	`minecraft:water_breathing`
Invisibility	`minecraft:invisibility`
Slow Falling	`minecraft:slow_falling`
Health Boost	`minecraft:health_boost`
Luck	`minecraft:luck`

Effects from other mods also work — use their ID in modid:effect_name format.
