Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/boulder.mjs';

const boulder = createAsset();
scene.add(boulder);                      // rests on y = 0, front faces +Z

JSX

import { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/boulder.mjs';

export function Boulder() {
  const model = useMemo(() => createAsset(), []);
  return <primitive object={model} />;
}

GDScript

# Import boulder.glb (download below). It is a static mesh, one material per colour.
add_child(preload("res://boulder.glb").instantiate())

// Import boulder.glb with glTFast (com.unity.cloud.gltfast).
// Drop it in the scene: 1 unit = 1 metre, +Z is its front.

Prompt

Use the gaitkit MCP server: get_variant({ "id": "boulder", "want": "default look" })
then place the result.

Knobs

Knob	Type	Values	Default	What it does
`size`	range	0.3 to 4, step 0.1	`1.2`	Rough diameter in metres. 0.3 is a stone you could kick, 4 is a landmark.
`shape`	choice	`round` `slab` `spire`	`round`	round (generic boulder), slab (flat, good for paths and seats), spire (tall standing stone).
`stone`	choice	`granite` `sandstone` `basalt` `chalk`	`granite`	granite (grey), sandstone (desert orange), basalt (volcanic black), chalk (pale white).
`cover`	choice	`none` `moss` `snow`	`none`	Paints the upward-facing facets with moss or snow so the rock matches its biome.
`seed`	range	1 to 50, step 1	`3`	Changes the facet pattern. Scatter with different seeds so no two rocks match.
