If you are using the Capture Pilot app on an iOS device in combination with running Capture One Enterprise, you have the option to display the overlay on top of the image viewed on the iOS app screen. The overlay can be toggled on and off in the Capture Pilot app by tapping on the Overlays icon at the bottom of the app screen. It is worth to point out that the visibility in the app is controlled independently of whether the overlay is enabled or not in Capture One Enterprise. This means that the same overlay can be hidden in Capture One Enterprise but visible in the Capture Pilot app or vice versa.
You will need to update the Capture Pilot app (version 2.2.x or later) to enable the Overlay functionality. Also note that Capture One Enterprise controls the location, opacity, and scale of the selected overlay. You cannot change the overlay on the connected device, you can only toggle the visibility on and off.
