Standardized Character Rigs & Animation Sets

Character rigging and animation are notoriously time-consuming for indie game creators. **Quaternius** solved this by designing modular character packs with **standardized humanoid bone hierarchies**.

Every character pack includes ready-to-use animations: **Idle, Walk, Run, Attack, Jump, and Death**. Because they share a uniform rig, developers can retarget hundreds of animations across multiple characters in Godot, Unity, or Unreal Engine in minutes.

Modular Low-Poly Environment Kits

Beyond characters, Quaternius creates stylized environment packs (Cyberpunk City, Fantasy Village, Modular Dungeon, Sci-Fi Station) built with clean geometric quad topology and shared lightweight texture atlases.

Yes! Most character packs include essential animation cycles (Idle, Walk, Run, Attack, Hit, Death) embedded in the FBX and glTF files.

How do I retarget Quaternius animations in Unity or Unreal?

Because the rigs use standard humanoid bone naming, you can configure the Avatar as ‘Humanoid’ in Unity’s Mecanim inspector or use the UE5 IK Retargeter for 1-click animation sharing.
