Coral Frag Rack
Code mode
See this model drawn out of its own program, then drag any number in it and watch that part re-form. It needs an account, and free models open on a free one.
Part of Office Reefscape kit
60 matching parts, one palette and scale
Use it
The fastest path in three.js: one import, zero loaders. The module returns a ready THREE.Group with named parts.
import { createAsset } from './coral-frag-rack-a0e7f9.mjs';
scene.add(createAsset());

The standard route: load the GLB with GLTFLoader. The same file works in any glTF pipeline (Babylon.js, <model-viewer>, custom engines).
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
new GLTFLoader().load('./coral-frag-rack-a0e7f9.glb', (gltf) => {
scene.add(gltf.scene); // real-world scale in meters, origin on the ground
});
Flat-shaded vertex colors on a single material: no textures to wire up, one draw call.
R3F takes any Object3D through <primitive>, and these modules
return a ready THREE.Group synchronously. No useGLTF, no loader, no
<Suspense>.
import { useMemo } from 'react';
import { Canvas } from '@react-three/fiber';
import { createAsset } from './coral-frag-rack-a0e7f9.mjs';
function CoralFragRack(props) {
const obj = useMemo(() => createAsset(props), [JSON.stringify(props)]);
return <primitive object={obj} />;
}
<Canvas camera={{ position: [3, 2, 4] }}>
<hemisphereLight args={[0xffffff, 0x998877, 1.2]} />
<directionalLight position={[4, 7, 5]} intensity={2} />
<CoralFragRack colorway="sps-cool" />
</Canvas>
Every knob is a prop. colorway="sps-cool" above is one of this
model's own parameters, so the component rebuilds when it changes, exactly like any other React
component. More on using these in R3F.
Self-animating models, and one draw call
A model that animates itself exposes
userData.tick(seconds). Drive it from R3F's own loop:
useFrame((state) => obj.userData.tick?.(state.clock.elapsedTime));
To merge a static set into a single draw call, import
mergeAssets from https://polyfork.dev/cdn/merge.mjs and pass the merged
group to one <primitive>.
- Buy the asset, then download the .glb from this page.
- Unity: drag the file into Assets (glTFast or UnityGLTF import it). Godot: drop it into the project, it imports natively. Blender: File → Import → glTF 2.0.
- Place it as-is: real-world scale in meters, origin at ground level.
- Materials arrive as vertex colors on one material: no texture files, nothing to relink.
Using Claude Code, Cursor or another coding agent? This site is built for them: agent-readable docs at /llms.txt and a JSON API at /api. Paste this prompt:
Your agent authenticates with an API key: create one under My assets after purchase, and it can fetch everything you own.
I own "Coral Frag Rack" on polyfork.dev. My API key is in
the POLYFORK_KEY env var. Download it into my project and add it
to my three.js scene:

(both with header Authorization: Bearer $POLYFORK_KEY)
Site docs for agents: https://polyfork.dev/llms.txt
Every asset in this catalog shares one identical vertex-colored material, with no textures at all. That means whole scenes collapse into a single draw call: the same result Synty-style packs get from a texture atlas, without the atlas.
import { mergeAssets } from 'https://polyfork.dev/cdn/merge.mjs';
// position your assets first, then:
const { merged, dynamic } = mergeAssets([
terrain, tree, rock,
asset,
]);
scene.add(merged); // ONE draw call, static
dynamic.forEach(d => scene.add(d)); // rigged parts, still movable
Placing many copies of one model? Use THREE.InstancedMesh instead: one draw call and even less memory. The landing page's forest demo ends with exactly this merge.
