Trying something different GPT 6 Astra + Blender to create a 3D playable game for the browser. Using WASM + WebGPU ... skipping the need for ThreeJS entirely. - GPT Images 2.5 for Mockup + Reference Images - GPT 6 Astra xHigh - Blender MCP

Ask your agent to use ECS and create complex large scale simulations I think for a small game Threejs would be fine. Wasm is most useful for complex cpu work and ECS helps make efficient use renderer calls and memory usage, which benefits a lot from direct webgpu use.

Inspired by this post by @pvncher Several reasons why you might want to skip ThreeJS - but he outlines some compelling ones here.

Amazing!!!

Thanks George!

Result is amazing !

Thanks! Pretty pleased with it yeah! Unlocks new possibilities

Can you go inside the shop? I'd happily waste twenty minutes poking around in there.

Good idea! What do you think would be worth messing around doing in there?

直接在浏览器里玩 3D，已经有点离谱了

the WASM + WebGPU skip is the interesting move. what's the actual runtime bridging Blender to the browser, are you going through Godot export or something more custom?

Skipping ThreeJS is a bold move

Looking great! I'm trying this for a little italian island. It's taking forever, and the results look nothing like the concept art. It takes a ton of time with agents to force them into tiny details. They take so many shortcuts.

Nice man looks great. Have u seen any different in quality of results in having Astra use computer use and control Blender vs just Blender mcp?

Thanks! I've actually not used computer use with Blender - Blender MCP has worked very well for me.

I've had mixed results with Blender MCP, especially when it comes to animations. Found this repo which seems quite amazing looking at the demos, what you think have you given this a try? They're all procedurally generated:

I've seen this! I think it uses Trellis ? Not tried it myself - but I've had pretty good results with just Blender MCP except for characters

I am giving it a try now and will report back my findings/results for u :)

Reference image and results with image2threejs here. Not super happy with the results, but could also be me doing smth wrong.

Still tough to do characters - would recommend using Meshy / Tripo

I tried this but AI still went with three.js

why did you ditch three.js or phaser? they no longer add value to the pipeline?

I still love Phaser for 2D games!

The WASM + WebGPU route is a bold constraint—skipping Three.js should make the architecture much leaner. Curious how you’re handling input and scene streaming once the Blender scene grows.
