Definitely something I can see coming in the future, especially once an Oculus Quest (or another standalone vr headset) is released with better than smartphone hardware (or of course smartphone hardware that is powerful enough), so that Enscape standalones can run directly inside the headset, even if just in Draft/Medium Rendering Quality in the beginning.
Another solution, which will require a PC though, would be using the Quest wirelessly, but then you'd also need a good internet connection at the clients place. This would still help with avoiding cables that can reduce the immersion. Just so you're aware that this is an option if this is new to you!
Summed up, the future is holding a lot of great things when it comes to VR in general like better displays, no cables, standalone hardware, even better room-tracking etc.
It is nice to hear you could see it in the future.
about the one where you run it with the PC and the wireless Quest, can you do that with the exe standalone or du jo need to do it through sketchup and Enscape?
