### Remarks

Preview are done with the SceneView's preview widget. When selecting a camera to preview, this method will be called to determine if the camera is previewable or not. The default implementation of this method consider every camera is previewable, but it may not be the case for the custom RenderPipeline you write on your own. If it is the case, override this method.
