Hi Team,

After upgrading to SDK 1.6.x we noticed that the ov_overlay for voxl-open-vins-server is not present anymore.
Is there any plan to bring it back since this is quite helpful for debugging OpenVINS in different environments and with different camera setups.

Thank you for you help!

Best,
Joel

@saegsali What platform are you running? If you arm and get the drone in the air does the ov_overlay appear? This change was made to reduce CPU load on the ground, it can likely be turned off in `/etc/modalai/voxl-open-vins-server.conf`

@tom  Thank you for your answer!

Unfortunately the overlay does not appear, even when the drone is armed. We are using Starling 2 drones with SDK 1.6.2.
Also in the ```voxl-open-vins-server.conf``` we can't find a setting for something related to the overlay.

Do you have any ideas what we can try to see the ov_overlay again?

Thank you in advance!
