Right, I agree that they are turning on the IR Flood, but I'm stuck figuring out how to turn it on. If I try and turn it on before running their software, I get an error. If I turn it on after running their software, it seems to work. At that point I'm able to turn it off and on and see the resulting change.
But they must being doing something in addition to turn it on, or possible unlock the setting.
Btw/ I'm using the OpenNi2 SDK.
