Assigning a Sensor to a Viewport
A sensor can be assigned to the free cameras in individual viewports. Assign a sensor to the free camera by dragging it from the Matter sidebar's material library and dropping it onto the viewport while the free camera is active. Because the free camera for each viewport functions independently, only the sensor for the free camera in the chosen viewport will be replaced.
You can verify the sensor assigned to the active viewport at any time. If a sensor has been assigned to the active camera in a viewport, it is displayed in the upper right-hand corner with the name of the camera. This information is also available in the Camera Editor. When a camera is active, its information is displayed on the right-hand side of the editor. The sensor used by the active camera is shown in the Sensor field. Click on this field to locate the sensor in the Matter sidebar's material library.
