@fMinZhou @happycapyai love the visual and the game idea!

[Nelson P.Klark @nelsonpatrao]

@SimonasLTU1 @tripoai @threejs @OpenAIDevs Nice !

[Nelson P.Klark @nelsonpatrao]

@Nal_uh This is really nice! Well done!

[Nelson P.Klark @nelsonpatrao]

@Tim_LB @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp For sure! I did look into existing libraries, but I wanted to build it myself this time to really understand the ins and outs. Now that I’ve learned from the process, using a library would definitely speed up the next iteration.

Thanks! I read your article, really interesting.
Here’s the rough breakdown:
• 1h: first pass using only GPT-6 Astra (medium) and @anshuc skill. The result was already strong enough to make me want to push it further.
• 2–3h: improved the characters and scene details with Astra (low) + GPT-5.6 Sol and meshy and blender MCP's.
• ~1h: prompt-by-prompt refinement, mostly with Sol.
Also prepared character design sheets and environment concept art to keep the art direction consistent. I’m working on a more in-depth article about the whole process.

@JonLugado @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp It's planned ;) , thinking about Goddot for a first spin.

@hi_im_ByooNg @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp Thanks for giving it a try! The city is still a little too ambitious with memory. An optimization pass is next, so your Mac ( and mine ) won’t have to make the ultimate sacrifice 🫡 😃

@chetanankola @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp Supa nice!

[Nelson P.Klark @nelsonpatrao]

@SimonasLTU1 @mindblown_ai nice idea!

[Nelson P.Klark @nelsonpatrao]

Thanks! I used ComfyUI for sound generation with Stable Audio 3 Medium Base. The world was built in Blender with the help of Blender MCP and GPT-6 Astra, although most of the environment is procedurally generated in code by GPT-6. For the characters, I created character-design sheets and used Meshy for the initial 3D models. I’m currently rebuilding them to achieve better quality.

@VinceLee766945 @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp Sure, you can try it here : https://t.co/uMs1wf62Ku

@masterofnone Nicely done! And I like the virtual sticker on mobile.

[Nelson P.Klark @nelsonpatrao]

@Tim_LB @anshuc Whoa, this is some serious work. Thanks for documenting the timings, costs, limitations, and even what the data can’t prove. This is genuinely useful! 🙌

[Nelson P.Klark @nelsonpatrao]

@threejs Already moved Helion City to r186. The updated Sky and better depth-aware steam integration fit the project beautifully, and the scene is still holding 60 FPS. Thanks for another great release!

@preyforge @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp You spotted him 😅 The technician character is definitely the haunted one. I’m actually reworking the character models, hopefully the next iteration will involve fewer paranormal handoffs 👻

@wik_plus @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp Reminds me Black and white game.
But yeah could be the beginning of a story line for a game ;)

[Nelson P.Klark @nelsonpatrao]

@fabiensnauwaert @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp Thanks, updating it to add some more.

[Nelson P.Klark @nelsonpatrao]

@Rykerbytecrypto @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp Thanks!

[Nelson P.Klark @nelsonpatrao]

@beiwei50 @mustafaakin Are you running it in a VM or on Linux? @mustafaakin, is the game WebGPU-only, or does it also have a WebGL fallback? WebGPU support on Chrome/Linux is still limited and depends on the GPU, drivers and display server, VMs can also lack GPU acceleration.

[Nelson P.Klark @nelsonpatrao]

@wik_plus @anshuc @OpenAI @MeshyAI @ComfyUI @GeminiApp I’ll take that as a compliment 😄 Now you’ve got me thinking about making Helion City more explorable. I might skip the endless loading screens and furniture microtransactions, though.
