Handling Tracking Loss
I've been making an app that kind of relies on your to be in dark environments, however in the dark, the HoloLens loses its ability to perform spatial mapping. That's not such a big deal for my app but I'd like to be able to suppress the popup that says "trying to map your environment". I've been following this guide here:
However, I am unable to follow it completely because the option to uncheck "Display Tracking Loss Image" is greyed out, as is most options in that part of the settings menu. Does anyone know how to enable those options?
