## About

A 4 m bay of defended curtain: a battered plinth, a solid body with one outer buttress and two arrow loops, a crenellated parapet on the assault face and a low kerb behind a 1.4 m wall walk. West and east ports on the 4 m grid chain bays into a run of any length, and the cracked and breached variants drop into the same run. Dimensions 4.00 × 4.60 × 2.45 m (X × Y × Z). Pivot on the grid origin with named connector ports. Metre units, +Y up, +Z forward. Kingdom limestone, ashlar, timber, oak, iron, cloth, slate and straw, the palette shared with the castle construction and faction building packs. 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/28834/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function AssaultWallBay4MMedievalSiegeAndCastleDefence(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/28834/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/28834/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/28834/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/28834/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
