I wanted to make a game. Getting a character to walk became a whole side quest. Training Grounds lets you preview 3D motion, export eight-frame sprite guides, and copy a prompt for your image generator. Walking, breathing, four directions, and local animated GLB import. Free and open source.
Hi everyone, Andy here.
I wanted to build a game. I thought getting a little character to walk would be the easy part.
Well…
After trying different prompts and sprite-sheet layouts, a 3D motion guide finally gave us something we liked. So I made that part into a small tool.
Training Grounds lets you choose a motion, adjust the camera, and export eight poses with a prompt. Bring your original character still to your own image generator. You can also open an animated GLB locally.
I built this with Codex during the Astra challenge. Three.js handles the guide, Quaternius provides the source walking motion, and ImageGen made the Hua example. Image generation is a separate step; there is no generation API hiding behind the download button.
It helped my character finally walk. I hope it helps yours too.
What movement would you want to try next?
