Hi @Mr_i8studio, I’m using shapespark in my architect every day work and I sell VR services to my colleagues too.
My equipment is based on windows mixed reality and I have a Samsung odyssey headset (best resolution two years ago) also have a sheap cardboard type head set that I don’t use anymore because it is too little to my phone Huawei Mate 20 pro. You have many cardboard type VR headset options in Amazon, be careful with supported phones.
I prefer Android from iOS because VR environments already settings in Android not always in iOS.
With windows mixed reality and Samsung Odyssey in my Acer Aspire (Core i7-8750. Nvidia GTX1060) I always have very good esperiences showing shapespark scenes. Some minor issues related with this technology mix but no worries.
I have a plan to buy a new headsets this year and I already studied the Oculus Quest for a simple reason, is wireless! but I read about pour resolution and some issues whit big files, so I’m not decided yet.
I hope this info help you in some way!
