A horror game's monster hand-animated in Blender by Claude

The full story

A short three.js horror game had a monster first made in October from a single T-pose image with Tripo's H3.1 model. The developer ran the same image through Tripo's newer P2 model, getting one 21,000-triangle mesh with one texture and a full skeleton including finger bones, in place of 14 separate pieces and 14 textures.

The finger bones meant the monster's fridge-shove could be animated by hand, so the developer had Claude drive Blender live and directed it with notes such as "lock their arms out and lean into it". When the end pose still looked wrong, one screenshot of the bad frame and a higher effort setting fixed it in a single pass. One script imports the model into the game, where the shove plays with the fridge moving under the monster's hands.

The post is a paid partnership with Tripo AI; the animation work in Blender is Claude's.
