Use it

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

JavaScript

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

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

// 'blast_door' pivots on its hinge: -110° to 0° around y
bunker.getObjectByName('blast_door').rotation.y = THREE.MathUtils.degToRad(-110);

JSX

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

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

GDScript

# Import bunker.glb (download below). Moving parts are separate nodes, pivoted on their hinge.
$Bunker/blast_door.rotation_degrees.y = -110

// Import bunker.glb with glTFast (com.unity.cloud.gltfast).
transform.Find("blast_door").localEulerAngles = new Vector3(/* y: */ -110, 0, 0);

Prompt

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

Knob	Type	Values	Default	What it does
`shape`	choice	`octagon` `round` `square`	`octagon`	Plan of the pillbox: octagon (classic eight-sided), round (twelve-sided, almost a drum) or square (a boxy blockhouse with one front slit).
`camo`	choice	`woodland` `desert` `arctic` `grey` `bare`	`woodland`	Paint scheme on the concrete and the colour of the earth berm: woodland (olive, brown and black blotches on grass), desert (sand and tan), arctic (white and pale grey in snow), grey (urban greys), bare (unpainted weathered concrete).
`size`	range	2 to 3.5, step 0.25	`2.6`	Corner radius of the bunker in metres; 2 is a two-man pillbox, 3.5 a command blockhouse about 7 m across.
`sandbags`	toggle	on / off	`true`	A ring of sandbags around the edge of the roof slab.
`doorOpen`	toggle	on / off	`false`	Swings the steel blast door wide open (110 degrees), showing the dark doorway.
