## NullLayer interface

A null layer is used as a transform parent for other layers. It does not render anything on its own.

**Signature:**

```typescript
interface NullLayer extends LayerMixin
```

**Extends:** [LayerMixin](/en/creator-api/nodes/layer-mixin)

## Remarks

When a null layer is a transform parent of another layer, that child layer inherits the null layer's transform.

Note: the Creator UI refers to the null layer as a null object.

## Example

```ts
const controller = scene.createNullLayer({ name: "Controller" });

controller.rotation.addKeyframes([
  { frame: 0, value: 0 },
  { frame: 60, value: 360 },
]);
```
