Thanks very much to the community that identified some initial issues with our demo! We have been able to take care of several of these issues with a new hotfix. We've just posted the hotfix and your steam clients should grab it on your next login.
Fixed:
-tablet toggle
-ceiling and elevator collision
-music volume now lowers during safe cracking
-added loading/intro screen during initial load so users aren't staring at a black screen
-comfort mode can only be activated when a HMD is detected
-updated unreal engine to 4.11.2
We are still working on improving our VR controls based on user feedback. We'll be implementing VR hands instead of a full body mesh as well as setting up an optional look and click movement system for additional comfort. As soon as these features are ready we'll include them in our next patch!
