# CCORE GLB-3D-Coder ### Turn a text prompt into an editable 3D asset. **CCORE GLB-3D-Coder** is a specialized **4B coding model** for low-poly game assets and procedural scenes. Describe a character, prop, building, or environment, and the model writes a complete **Three.js HTML/JavaScript page** with a preview and an **Export GLB** button. Open the page, inspect the result, and export the asset for **Godot or another editor that supports GLB**. **CCORE project release · November 5, 2026 · Apache 2.0** Repository: `ccore/Qwen3.5-4B-GLB-3D-Coder` · Checkpoint: latest uploaded This independently developed CCORE model was trained using [Qwen/Qwen3.5-4B](https://huggingface.co/Qwen/Qwen3.5-4B) as its base. CCORE maintains this release. **Q4_K_M, Q8_0, and the original Safetensors weights are available now.** **The training dataset has also been released:** [**CCORE ThreeJS-3D-GLB-Assets**](https://huggingface.co/datasets/ccore/ThreeJS-3D-GLB-Assets) — **3,918 tested and rendered examples across 40 domains, with validated GLB exports.** **Important:** If you downloaded the model before **November 5, 2026**, **delete the old model files and download them again** in LM Studio or whichever app you use. The GGUF filenames haven't changed, so make sure you're loading the updated weights. **[Get the weights](#weights-and-release-status) · [Training dataset](https://huggingface.co/datasets/ccore/ThreeJS-3D-GLB-Assets) · [Use the model](#quick-start) · [Prompt ideas](#domains-and-prompt-ideas) · [Upcoming releases](#what-comes-next)** ## RIFTWARD — playable arena showcase **RIFTWARD: Guardians of the Ancient** is a browser arena built with character, terrain, architecture and environmental assets generated with **CCORE GLB-3D-Coder 4B using the latest uploaded checkpoint**. The assets were assembled, refined and integrated into a playable game with assistance from an **orchestration and validation harness**, which also handled gameplay systems, interface, effects and testing. [![RIFTWARD gameplay — assets generated by CCORE GLB-3D-Coder](images/riftward-gameplay.gif)](https://huggingface.co/spaces/ccore/RIFTWARD) [**Play RIFTWARD on Hugging Face Spaces**](https://huggingface.co/spaces/ccore/RIFTWARD) · [**Starter prompt for any coding agent**](https://huggingface.co/spaces/ccore/RIFTWARD/blob/main/agent-starter-prompt.txt) The game runs entirely in the browser using exported GLB assets; no live model inference is needed to play. The Space includes a copyable prompt explaining how to connect a coding agent to a local model API and build a game from its outputs. ## Community showcase **Naoki Kishida (@kis)** created a **playable 3D RPG demo** using assets generated with **the earlier preview version of GLB-3D-Coder**. [![Gameplay from Naoki Kishida's 3D RPG demo, built with assets generated by the earlier preview version of GLB-3D-Coder](images/community-rpg-naoki-kishida.gif)](https://kishida.github.io/webdemos/rpg-3d-glb/) [**Play Naoki Kishida's 3D RPG demo**](https://kishida.github.io/webdemos/rpg-3d-glb/) Thanks to Naoki for sharing this project with the community! ## Examples beyond the training data Here are some examples the model created from **prompts that were not included in its training dataset**, ranging from short requests to detailed asset descriptions. The images below come from the project's showcase video. **Comparison setup:** Both models received the same prompts, with DeepSeek set to **high reasoning effort**. In each comparison, **DeepSeek V4.1 Flash 1017 is on the left** and **CCORE GLB-3D-Coder (4B) is on the right**. ### Coral-armored lighthouse keeper [![Coral-armored lighthouse keeper: DeepSeek V4.1 Flash 1017 on the left and CCORE GLB-3D-Coder on the right](images/coral-armored-lighthouse-keeper.png)](images/coral-armored-lighthouse-keeper.png) **Prompt for both models:** `Create a coral-armored lighthouse keeper.` ### Frozen goblin watch camp [![Frozen goblin watch camp: DeepSeek V4.1 Flash 1017 on the left and CCORE GLB-3D-Coder on the right](images/frozen-goblin-watch-camp.png)](images/frozen-goblin-watch-camp.png) **Prompt for both models:** `Create a frozen goblin watch camp.` ### Magnetic-rail rescue engineer [![Magnetic-rail rescue engineer: DeepSeek V4.1 Flash 1017 on the left and CCORE GLB-3D-Coder on the right](images/magnetic-rail-rescue-engineer.png)](images/magnetic-rail-rescue-engineer.png)

Prompt used for both models

```text Create a magnetic-rail rescue engineer character. Show an adult specialist in a grounded stance wearing a charcoal work suit, orange safety panels, insulated gloves, a compact helmet, and heavy boots with visible magnetic sole plates. Equip the character with a coil-testing wand, a folded emergency rail clamp, a shoulder radio, and a silver power pack connected to the tool belt by a thick blue cable. Make the proportions, cable route, pack mounting, tools, and protective equipment mechanically plausible. Use a plain presentation without extra scenery. Keep it static. ```

Prompt used for both models

```text Create a compact bioluminescent cave tram station scene. Include a short raised platform with safety rails, a small two-seat mine tram on narrow rails, a hand-operated cable winch, a ticket pedestal, a bench, and six blue glowing crystal lamps mounted in protective cages. Use dark stone, weathered timber, black iron rails, teal tram panels, and cyan crystals. Make the wheel flanges, rail spacing, cable route, platform supports, lamp cages, and passenger access mechanically coherent. Use a plain presentation without surrounding cave walls or extra scenery. Keep everything static. ```

Available now — original, unconverted checkpoint. | | Optional BF16 vision projector | [mmproj-Qwen3.5-4B-BF16.gguf](https://huggingface.co/ccore/Qwen3.5-4B-GLB-3D-Coder/resolve/main/mmproj-Qwen3.5-4B-BF16.gguf?download=true) | **644 MiB**; needed only for image inputs in a compatible multimodal GGUF runtime. | The optional projector is the original, unmodified Qwen3.5-4B vision encoder/projector from [lmstudio-community/Qwen3.5-4B-GGUF](https://huggingface.co/lmstudio-community/Qwen3.5-4B-GGUF/tree/f9f88ac3e234be915e23811a6d28ea287bdb927e), provided under Apache 2.0. ## Quick start 1. Load a GGUF in a runtime that supports Qwen3.5, or load the original checkpoint with its configuration, tokenizer, and chat template. 2. Set the **system prompt** and **sampling parameters** below. 3. Send an English asset request. Start with a short idea, or specify the parts, materials, colors, layout, and animation you need. 4. Save the complete generated HTML as an `.html` file and open it in a browser. The page may load Three.js and its add-ons from a CDN. 5. Inspect the scene, click **Export GLB**, and import the downloaded `.glb` into your editor. Request animation explicitly when you need it, and check that it is included in the exported GLB. ### Sampling settings | Parameter | Value | |:---|:---| | Temperature | **0.8** | | Top K | **40** | | Top P | **0.95** | | Min P | **0.0** | | Repeat penalty | **1.0** | The recorded evaluation used these settings with thinking enabled. Allow enough output tokens for the complete HTML; detailed scenes can produce long responses. ### Output length and thinking | Parameter | Recommended setting | |:---|:---| | Maximum output tokens | **Unlimited — `-1` where supported** | | Thinking / reasoning | **Enabled, with no effort limit or separate thinking-token budget** | **Allow the model to finish generating.** The model was trained on examples reaching **72K tokens**. Responses average around **20K tokens**, and some can be longer. **An 8K output limit is too restrictive for these generations** and can stop the response during thinking or before the HTML is complete, leaving incomplete or unusable code. Set the output limit to **unlimited (`-1`)** in runtimes that support it. **Keep thinking enabled, without limiting reasoning effort or imposing a separate thinking-token budget.** I have not validated generation quality with thinking disabled, truncated, or restricted. Unlimited output removes the explicit generation cap; the runtime's context and resource limits still apply. ### System prompt ```text Create game assets for the Godot editor, which uses GLB files. Create whatever the user requests as a good-quality low-poly asset using only Three.js in one complete standalone HTML file. The HTML must show the asset and include an Export GLB button that downloads a working GLB. If the requested asset needs animation, add it and include the animation in the exported GLB; otherwise make it static. ``` ## Domains and prompt ideas Use these categories to explore the model and shape your requests. | Domain | Prompt idea | |:---|:---| | Characters and NPCs | `Create a village blacksmith wearing a blue apron.` | | Enemies | `Create a swamp goblin scout with a wooden shield.` | | Bosses | `Create a stone golem boss with glowing green crystals.` | | Companions and creatures | `Create a tiny fox companion wearing a red scarf.` | | Weapons and armor | `Create a short iron sword with a leather-wrapped grip.` | | Items, tools, and pickups | `Create a blue mana potion in a hexagonal glass bottle.` | | Props and furniture | `Create a weathered wooden workbench with a small lantern.` | | Nature and environment | `Create a pine tree growing on a rocky mound.` | | Modular architecture | `Create a stone dungeon doorway module with an iron frame.` | | Interactive objects | `Create a wooden gate with an opening animation.` | | Ground transport | `Create a compact courier motorcycle with cargo boxes.` | | Air and space transport | `Create a small cargo airship with twin propellers.` | | Watercraft | `Create a weathered fishing skiff with nets and wooden crates.` | | Industrial machinery | `Create a compact mining conveyor with metal support legs.` | | Laboratory and medical assets | `Create a portable botanical analysis station with sample jars.` | | Urban services | `Create a modern bus stop with a bench and route sign.` | | Sports and playgrounds | `Create a small playground climbing wall with colorful holds.` | | Farming and homestead | `Create an orchard harvest cart filled with wooden fruit crates.` | | Cuisine and markets | `Create a bakery display counter with bread baskets.` | | Museums and field research | `Create an ancient artifact display case on a stone pedestal.` | | Traps and hazards | `Create a hidden spiked floor trap with stone tiles.` | | Festivals and ceremonies | `Create a harvest festival booth with colorful banners.` | | Battlefield scenery | `Create a reinforced frontier command post with sandbag defenses.` | | Underwater structures | `Create a coral observation dome with a small docking platform.` | | Puzzles and gameplay markers | `Create a glowing rune sequence console with three stone buttons.` | For a detailed request, name the main object first, then describe its components, colors, materials, placement, and intended movement. The exact prompts in the gallery provide examples of longer briefs. ## Current limitations Some requests need a retry or a small code correction. Inspect the exported asset in your editor, since materials, lighting, and animations can differ from the browser preview. ## What comes next The training dataset is now publicly available: [**CCORE ThreeJS-3D-GLB-Assets**](https://huggingface.co/datasets/ccore/ThreeJS-3D-GLB-Assets). Beyond this release, I want to build **larger, carefully reviewed datasets** and **more capable small models**, including specialized models in other areas. I've developed and funded this work myself, and I'm releasing the **models, weights, and datasets free of charge to the community**. Next, I'm planning **100,000 high-quality examples for 3D and general-purpose coding harnesses** to **train new small models** that can use tools, test their outputs, and refine their work through iteration. I expect **creating these datasets and training the new models to require around 20 times the effort of the current project**. **I need the community's support to make this next stage possible.** ## Support the project I cover the cost of data preparation, validation, experiments, and GPU training myself.
