Summary

Spine-style 2D skeletal animation with bones, skinning, weight painting and Spine JSON import.

Description

A source-available 2D skeletal animation editor built on Godot, with Spine JSON import, bone hierarchies, inverse kinematics, skinning, weight painting, keyframe animation and resource export. Provides its own document format and runtime integrations rather than using Spine's editor or commercial runtime.
