If I press the left cursor key, the camera will gradually clock its yaw to the left, if I press the up cursor key, the camera will do the same with pitch, and so on.
The stock VR project template is sufficient for reproducing this behavior.
I just tried with a Windows machine (as I’m using Linux at home) and I see the same (new) behavior. I’m using Chrome.
Also of note, I no longer see the “No VR display or headset is detected.” text display immediately. I definitely don’t have VR hardware connected.
I didn’t update Chrome, although I have since updated it.
The WebVR implementation has changed since I last looked at and looking at window.WebVRConfig has MOUSE_KEYBOARD_CONTROLS_DISABLED set to false which may be why the cursor keys are moving the camera. @dave may have more ideas?
