Camera Preview is an add-on that displays a real-time camera view directly within the 3D viewport, functioning similarly to the camera preview feature found in Unreal Engine. It allows users to monitor their camera framing without having to switch their main viewport into camera view mode.

The tool supports displaying previews for multiple cameras simultaneously. Users can customize the interface by adjusting the position, offset, and size of the preview window. Additionally, specific objects can be hidden or unhidden exclusively within the camera preview using an operator located in the object context menu. Note that Cycles rendered mode and camera background images are not supported within the preview window.
