Visual Position Not Working

I’m trying to create an indoor setup without GPS, instead using visual position estimate to provide localization. I configured the parameters for EKF to use vision rather than GPS, and I can confirm from the message viewer that the EKF is correctly localizing with the information. However, QGroundControl simply shows “no GPS lock for vehicle” and there is no red arrow on the map showing my vehicle

. Does QGroundControl support visual positioning? If so how can I tell it to ignore the absence of a GPS and use the visual odometry? Again, I know that the estimator is correctly localizing and I can see it moving around in the log files.
