for me the tool crash when you select something, but if you re-run it you see that the "Debug HMD type" feild is still set to whatever you clicked (unles it's CV1. for CV1 it goes back to DK2, sadly.) and you can launch your own software without a rift attached
Edit: Well, it doesn't seem that the runtime bother populating the "mirror texture" in this mode, so you can see how it actually renders to the headset, nor chek the values on the PerHud.
I've remarqed that you need to "Press A" on the health and safety warning for this to work, but you can't do it in this mode. Pressing A on the Xbox controller doesn't do it (it just sends the input to the game itself)
The problem itself is still interesting...
