@yosun What version of the Oculus SDK are you using? Are you encountering any error messages, or are the grab interactions simply not triggering in the Play mode?
Some scenes are better suited for VR than others, so we don't plan to have every demo designed with VR/desktop interoperability in mind.
@arturitu That's correct for now. We're currently hammering out the best way forward to ensure that devs can work with the latest, most stable tools possible. Building on the bleeding edge of VR means that things change really fast, and we appreciate everyone's patience as we chart the best way forward.
