Discover Monster Mash, the sketch-to-3D character tool! Learn how to use its Draw, Inflate, and Animate modes effectively in 2025. See how it stacks up against other 3D model generators.

Monster Mash is a really cool tool that makes creating and animating 3D characters much simpler. It is a sketch-based modeling and animation program. What’s neat is you can just sketch out a character, turn that sketch into a 3D model, and then animate it, all right there on the sketching plane. You don’t need to get bogged down with complicated 3D manipulation. Monster Mash gives you three main ways to create: Draw, Inflate, and Animate.
In the Draw mode, you sketch out your character’s parts. You use strokes to outline different areas, and you can even tell the tool which parts are in front of others. This project was actually shown at the SIGGRAPH Asia 2020 conference. You can try it out for free for evaluation and research, and they’ve got a great user forum if you need support or want to share feedback.
Daniel Sykora and his team at “GeometryFactory,” a research group at the Czech Technical University in Prague, are the masterminds behind “Monster Mash.” They teamed up with Google Research to bring this tool to life. It’s designed to let you sketch characters, then easily “inflate” them into 3D models, and finally animate them without a hitch. Their work was a highlight at the SIGGRAPH Asia 2020 conference, and you can find their research published in ACM Transactions on Graphics.
Monster Mash is handy for a bunch of tasks, like:
This tool is a great fit for anyone working with 3D characters or visuals:
