Dragon Bones is an open source 2D bone-based animation tool designed for game developers, animators, and digital artists. It streamlines the animation process by enabling users to create smooth, lightweight animations with bone rigging and mesh deformation.
- Skeletal Animation System: Create and manipulate bone structures for fluid, natural movement without redrawing frames.
- Mesh Deformation: Fine-tune your character’s skin and body with flexible mesh editing for more expressive animations.
- Inverse Kinematics (IK): Easily rig and animate complex joint systems with natural movement using IK constraints.
- Real-Time Preview: Instantly test and adjust animations within the app, reducing iteration time.
- Texture Atlas Support: Automatically pack images into atlases to optimize game performance.
- Multi-Platform Export: Export animations to various formats compatible with major game engines like Unity, Cocos2d, and HTML5.
- Free and Lightweight: Completely free to use with a small install size and low system requirements.
Whether you’re building characters for a mobile game or crafting cinematic cutscenes, Dragon Bones offers a robust set of tools to bring your 2D art to life.
