## FromStream(Stream, FileFormat, CancellationToken) {#fromstream}

Opens the scene from given stream using specified file format.

```csharp
public static Scene FromStream(Stream stream, FileFormat format, 
    CancellationToken cancellationToken = default)
```

| Parameter | Type | Description |
| --- | --- | --- |
| stream | Stream | Input stream, user is responsible for closing the stream. |
| format | FileFormat | File format. |
| cancellationToken | CancellationToken | Cancellation token to the load task |

### Exceptions

| exception | condition |
| --- | --- |
| IOException | Thrown when failed at reading input |
| [ImportException](../../importexception/) | Thrown when input is not a valid 3D format |

## Examples

The following code shows how to create a scene from a stream

```csharp
using(var stream = new FileStream("input.fbx", FileMode.Open))
{
    Scene scene = Scene.FromStream(stream);
}
```

```csharp
var opts = new FbxLoadOptions();
opts.LookupPaths.Add("textures");
using(var stream = new FileStream("input.fbx", FileMode.Open))
{
    Scene scene = Scene.FromStream(stream, opts);
}
