For a while i'm using Stingray to create a VR presentation and our client likes it. I created a simple menu, some camera and a pause/play of animation to present. I'ts very surprising that Autodesk suddenly stop developing it. I think there is a big market for this specially it is now added in 3DMax (interactive). I think a adding a simple menu (e.g. lights, touch screen control (moves).. and dash board (car menu).. will make this 3Dmax interactive more powerfull and a great software for BIM.
