## About

A 3.6 m steel stair up the outside of an alley building: two raking stringers, twelve open treads with grip bars, a top landing at 3.3 m and a tubular handrail on both sides. Origin at the bottom of the stringers. Overall 4.740 x 4.540 x 1.200 m (X x Y x Z), metre units, +Y up, +Z forward. Resting on y=0. Izakaya Alley and Ramen Shop / izakaya-std-v1: worn tarmac and grey render, warm and dark stained timber, brushed steel, charcoal ironwork, glass, and indigo, vermilion and cream for the noren, the lanterns and the signs, with embedded procedural concrete and timber maps and no custom shaders. Every sign face, noren, lantern, can, bottle, keg, crate and machine front is blank or carries invented abstract shapes: there is no lettering anywhere in this pack, in any script, and nothing copies a real trader, brand or product. 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/36413/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function ExternalStaircaseIzakayaAlleyAndRamenShop(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/36413/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/36413/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/36413/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/36413/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
