# UseEnvironment <Badge type="warning" text="^1.7.0" />

`useEnvironment` composable that automatically sets up a global cubemap, which affects the default `scene.environment`, and optionally `scene.background`.

It uses the [CubeTextureLoader](https://threejs.org/docs/#api/en/loaders/CubeTextureLoader) to load the cubemap

## Usage

```ts
import { useEnvironment } from '@tresjs/cientos'

const texture = await useEnvironment({
  files: [
    '/textures/environmentMaps/0/px.jpg',
    '/textures/environmentMaps/0/nx.jpg',
    '/textures/environmentMaps/0/py.jpg',
    '/textures/environmentMaps/0/ny.jpg',
    '/textures/environmentMaps/0/pz.jpg',
    '/textures/environmentMaps/0/nz.jpg',
  ],
  path: '',
  encoding: sRGBEncoding,
})
```

Then you can use the `texture` in your scene:

```html{3}
<TresMesh>
    <TresSphereGeometry />
    <TresMeshStandardMaterial :map="texture" />
</TresMesh>
```

| **path**       | `boolean`  | `false`                                                                        | Path to the environment map files.                                |
| **encoding**   | `Encoding` | `sRGBEncoding` for an array of files and `LinearEncoding` for a single texture | Encoding of the environment map.                                  |
| **background** | `boolean`  | `false`                                                                        | If `true` the texture will be used as the scene background.       |
| **blur**       | `number`   | `0`                                                                            | Blur factor between 0 and 1. (only works with three 0.146 and up) |
| **preset**     | `string`   | `undefined`                                                                    | Preset environment map.                                           |
