Charios

Charios is a browser-based 2D game character animation tool that turns layered character artwork into rigged, animated assets. It can automatically detect separate body parts in a PNG, prepare them as layers, and snap joints to bones. Users can adjust layers, repaint parts, change bone dimensions, and preview deformation live. Its animation library includes humanoid motion-capture clips, while users can also import compatible BVH and FBX files and retarget them to their character. A built-in play-test mode lets creators test actions directly in the browser. Charios can export assets for game development workflows, including Unity, while providing JSON and image-based exports for other production needs.
