Universal Animation Library 2: Cross-Engine Animation Pack.
by Jettelly
Published |
Animation packs are often tied to a specific engine, skeleton, or export setup, which makes reuse across projects harder than it needs to be. Universal Animation Library 2 takes a different approach by centering everything around a single humanoid rig designed for broad compatibility, allowing the same animations to be reused across engines and pipelines with minimal friction.
Created by Quaternius, Universal Animation Library 2 expands on the first library with a significantly larger and more varied set of motion data, targeting common gameplay scenarios rather than niche animation needs.
Do you need 130+ animations that are really easy to use and retarget in Godot, Unity and Unreal?

What the Library Includes
Universal Animation Library 2 ships with more than 130 humanoid animations covering a wide range of movement and interaction types. The focus is on practical actions that frequently appear in games, prototypes, and interactive projects.
The animation set includes:
- Melee and armed combat actions
- Multi-hit combo sequences with separated strikes and recoveries
- Parkour-style traversal and movement
- Farming, fishing, and everyday interaction loops
- Zombie locomotion and character movement states
Animations are organized to support both individual actions and longer sequences, making them usable as standalone clips or as building blocks inside animation state machines.
Universal Rig and Cross-Engine Support
All animations use a universal humanoid rig, which allows them to be retargeted easily across modern engines. The author provides tested exports for:
- Godot
- Unity
- Unreal Engine
The library includes engine-ready animation files (FBX, glTF, OBJ), along with a Source version that ships with the original .blend file containing the full rig and animations for further adjustment in Blender.
Relationship to the First Library
Universal Animation Library 2 is designed to complement the original release, not replace it. When combined, both libraries provide around 250 humanoid animations built on the same rig structure, making it possible to integrate the new set into existing projects without changing pipelines.
Free and CC0 Licensing
A significant portion of Universal Animation Library 2 is available for free. Roughly 60–70% of the pack can be downloaded at no cost, with the remainder offered as a paid option.
All animations are released under a CC0 license. This means they can be used freely in personal, educational, and commercial projects without attribution requirements. For developers and teams, this removes licensing overhead and makes the pack suitable for everything from quick prototypes to shipped games.
Practical Use Cases
Universal Animation Library 2 fits well in scenarios where:
- Rapid prototyping requires ready-made character motion
- Teams need placeholder or final animations without commissioning custom work
- Projects target multiple engines or toolchains
- Developers want animation assets that can survive engine changes over time
Because the library focuses on general-purpose movement and interaction, it is especially useful early in development, when gameplay systems are still evolving and animation needs tend to change frequently.
Similar & Useful Tools
- Human Mega Animations Pack: A comprehensive paid Unity animation pack featuring a broad set of humanoid animations covering various actions and behaviors (villagers, combat, workplace motions, etc.). It’s larger and more varied than basic motion packs.
Differences: Human Mega Animations Pack is broader and deeper than the free basic packs with many animation clips—but it’s Unity-specific and usually pricier. Universal Animation Library 2 is engine-agnostic and CC0 licensed, with direct exports for Unity, Unreal and Godot making it more flexible across pipelines.
- Locomotion Animations (Polygonmaker): A smaller Unity animation pack that focuses on humanoid locomotion animations (walk, run, crouch, etc.) optimized for Mecanim retargeting.
Differences: Locomotion Animations gives you movement-centric clips only and is more limited in scope. Universal Animation Library 2 includes combat, parkour, farming, fishing, and combo sequences in addition to basic locomotion.
