CCORE's GLB-3D-Coder Turns Text Prompts Into Editable 3D Game Assets
A specialized 4B Qwen fine-tune writes complete Three.js pages that preview low-poly assets and export them as GLB files ready for Godot.
- CCORE GLB-3D-Coder is a 4B Qwen3.5 fine-tune that generates Three.js HTML pages exporting low-poly GLB assets
- Released Apache 2.0 with Q4_K_M, Q8_0, and Safetensors weights; runs locally via llama.cpp, Ollama, LM Studio, vLLM
- Training dataset of 3,918 rendered, GLB-validated examples across 40 domains released too
- Responses average 20K tokens; an 8K output cap will truncate and break generated HTML
- Showcased in RIFTWARD, a browser arena with all assets generated by the model
- Next milestone: 100K-example datasets for small models that test and refine their own outputs
GLB-3D-Coder is a 4-billion-parameter fine-tune that converts text descriptions into complete HTML and JavaScript pages for generating 3D assets. Each page uses Three.js, a browser-based 3D library, to render a live preview and export the result as a GLB file. GLB is the binary form of glTF, a format supported by Godot, Blender, and other 3D tools.
The fine-tune builds geometry through source code, making each asset inspectable, editable, and compatible with version-control diffs. CCORE released it under Apache 2.0 with Q4_K_M and Q8_0 GGUF packages, plus the original Safetensors checkpoint. Its Hugging Face page recorded about 20,000 downloads during the first week after release.
Prompt in, GLB out
The fixed system instruction asks the model to create low-poly assets using Three.js inside a single HTML file. When a prompt calls for movement, the generated page can also define animation clips and include them in the exported GLB.
- Describe a character, prop, building, vehicle, or small environment.
- Generate the HTML and JavaScript page.
- Open the page in a browser and inspect the live preview.
- Select Export GLB and import the file into a compatible editor or engine.
A prompt such as Create a village blacksmith wearing a blue apron. can produce the full page without additional scaffolding. Developers can then adjust dimensions, materials, colors, lights, animation parameters, and scene layout directly in the generated code.
