## About

A straight internal flight for the town kit: eighteen cast concrete treads and risers on twin stringers, climbing a 3.5 m storey over a 4 m run, with a tubular steel handrail on each side. It drops into the stair opening of the floor slab. Dimensions 1.44 × 3.52 × 4.19 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Overcast realism: weathered concrete and faded brick, olive drab, gunmetal and machined steel, with hazard orange and safety yellow accents and emissive loot glows in the grey, green, blue, purple and gold rarity ladder. Static geometry; no rig, animation, collision or navigation data.

## Use with three.js

```js
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/28197/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

```jsx
import { useGLTF } from '@react-three/drei'

export function InternalStairFlight35MBattleRoyaleTownAndAirfield(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/28197/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/28197/v1/model.glb')
```

```

## Blender

```python
# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.
import bpy
bpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/28197/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
```

## Godot

```gdscript
# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.
var packed := load("res://models/model.glb") as PackedScene
var model := packed.instantiate()
add_child(model)
```

## Unity

```csharp
// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,
// or load it at runtime straight from the CDN:
using GLTFast;
var gltf = new GltfImport();
if (await gltf.Load("https://cdn.3dassets.dev/assets/28197/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
