RigForge: A.I game art generator for 2d skeleton assets
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

2d skeleton assets are slow and expensive to make. Artists paint each character as dozens of separate parts. Riggers bind those parts to a skeleton, and animators pose and key every move by hand. A new character means doing all of that again. Even a new look for an existing character means repainting every part and fitting it back onto the skeleton. Image models can't solve this alone. They paint well, but they don't keep parts in place: pieces drift, shrink, or get "completed" (a face painted into a helmet, a foot onto a shin), and the rig breaks. RigForge wraps the models in plan, paint, measure and judge loops so the output still fits the skeleton. A reskin, a new character or a new animation that used to take days of art, rigging and animation work takes minutes. Small studios and solo developers get variety in their character rosters that only large teams could afford before.
