The Google VR SDK for Unity provides a method Code (CSharp): /// If a floor is found, populates floorHeight with the detected height. bool TryGetFloorHeight(ref float floorHeight); which I don't seem to understand or it may not be working correctly. Can I expect the device to estimate the real world distance from the headset to the real world floor or is this only a virtual value. So far it only ever reports -1.6f in the editor and on device. Positional tracking is supported by the Mirage Solo.
