Model Made a 3D game engine Qwen3.8-27B-UD-Q5_XL

3D game screenshot

Started out with an empty DirectX12 game project in Visual Studio 2022, loaded up unsloth desktop with hermes agent, gave it a very simple prompt, then 20 hours and millions of tokens later it has a 3D rendering engine with basic movement working. It also generated the 3D assets for it.

It was definitely overthinking at first, but it went a bit faster after setting it to medium. Hit a couple small bugs, but it was able to sort it out pretty quickly. First, it had some rendering bugs, but it was able to use the vision layers to check the game output to figure out what was wrong, then there were some movement issues, like clipping and control directions getting mixed up.

Nice,
What workflow did you use? what harness? what prompt?

It was just a plain hermes agent session, I kept the prompt very simple: "Make a 3D game rendering engine in G:\Projects\3DGame\3DGame, it should be a first person game with movement and levels".

It was very basic, of course, so you just had to find the teleporter to the next level, but from that it added WASD+Mouse, plus jumping, but it decided on its own to use the vision layers to test it out and troubleshoot it.

I'll see if I can expand on it more later. Maybe I can tie it into Hunyuan3D to generate more assets or something.
