I was at Develop3D Live on Tuesday and tried every CAD VR company out there. Nothing suffices. Nothing yet works better than Unity despite the workflow to get there being ridiculous. I have heard VRED works well too but have not tried it. Also hoping KeyShot 7 has some kind of VR setup.
As a lecturer I contacted AMD to get early beta to their ProRadeon plugin for SolidWorks and all they sent me was some terribly broken beta program each time. The one they showed at Develop3D was much more advanced but still only slightly better than Photoview 360 and nowhere near Keyshot or Visualise or VRED etc.
