Description

AzureLib is an animation and rendering engine for Minecraft mods. It started as a fork of GeckoLib 4.x and has since grown into its own library, with a reworked rendering pipeline, an extended Molang runtime, per-bone hitboxes, procedural animation tools and its own Blockbench plugin. If you've seen a creature in a modpack that crawls, lunges, bursts out of the ground or swings a weapon with real weight, there's a good chance AzureLib is animating it.

Players: you don't need to do anything with this mod. Install it if a mod you use requires it.

Features

Animation

Keyframe animation from Blockbench: rotation, position and scale on any bone, for entities, items, armor and block entities.
30+ easing functions plus per-keyframe interpolation.

Multiple controllers at once: run a walk cycle, an attack and a head-look together without them fighting each other.
Sound, particle and custom event keyframes: trigger effects and your own code at exact moments in an animation.
Molang support extended toward Bedrock parity: strings, arrays, for_each, this, and many additional entity queries.

Procedural & Gameplay Tools

Multi-hitbox system: define hitboxes per bone that follow your animated model, so a long tail or a burrowing worm can be hit where it actually is.
Bone transform & procedural pose API: drive bones from code on top of keyframed animation, including IK and bone constraints, spring-bone secondary motion, bone sockets/attachments, and 1D/2D blend spaces.
Morph mod compatibility with Walkers and ReMorphed, so morphed players play your mob's animations.

Performance

Reduced per-frame allocations and object pooling in the animation pipeline.
Binary-search keyframe lookup for long animations.
Optional bone and animation LOD to keep crowded scenes smooth (opt-in per renderer).

Tooling

AzureLib Blockbench plugin with exports matched to the library, including baking IK into keyframes.
Examples mod showing entities, items, armor and block entities working end to end.
