Armor Model API
Armor Model API lets armor sets render custom Bedrock and GeckoLib geometry through the vanilla armor pipeline, with glow and trim options for each piece.
What it does
Custom armor geometry is defined per armor set, covering robes, pauldrons, hats and skirts, from any cuboid-based Blockbench model. Each slot is placed by bones that follow the usual armor naming, with separate boot parts and a waist part anchored to the chest for leg pieces. Armor trims can use per-set trim textures, whether vanilla smithing-table trims or new artwork.
The mod works from bake to buffer on the same code path vanilla armor uses, so pose copying, render layers and buffers stay unchanged. Sodium and Iris see ordinary vanilla model rendering, and no custom vertex pipeline is involved. Armor Model API requires Fabric API on Fabric and runs on client and server. It is open source under the MIT License and is published for Fabric, Forge and NeoForge across 8 release versions, 1.20.1 – 26.3.
Key features
Per-set armor geometry
Each armor set can use its own cuboid-based model, shaped as robes, pauldrons, hats or skirts.
Emissive glowmasks
A hand-authored glowmask.png marks pixels that stay bright in the dark.
Radiant glow variant
A high-luminance layer shifts toward white and contributes to shader-pack bloom.
Custom render layers
A small interface lets developers add extra passes such as overlays or effects.
Vanilla armor behavior
Animations, crouching, water movement, armor stands, baby mobs, dyed leather, enchantment glint and the glowing outline all carry over.

Use cases
Who it’s for: Armor and class mod developers who want custom armor models without writing a separate render path, and modpack builders who pair such mods with shader packs.
How it compares
More RPG Library is client and server, open source under the MIT License and covers 1.20.1 – 1.21.1 on Fabric, Forge and NeoForge. Armor Render Lib is client-side only, open source under the MIT License and limited to Fabric for 1.18.2 – 1.19.2, so it does not cover the same versions or loaders. Ethecore is not open source and is published for Forge and NeoForge for 1.20.1 – 1.21.1.

What the author says
Renders armor with custom geometry authored in the Bedrock/GeckoLib.geo.json format, through the vanilla armor rendering pipeline. From bake to buffer this is 100% the vanilla code path — the same pose copy, render layers, and buffers vanilla armor uses. That is the whole compatibility and performance story: Sodium…
