Thanks for letting me know, I haven’t done any raytracing for VR yet but was thinking to do so. Have you tried ? I am assuming it will be very demanding plus client will need an RTX system to run the content w/raytrace reflections and VR.
On the same presentation above at around 15:25 they show a switch to change from raytrace to screen space reflections, I am thinking that could come handy to build a blueprint that can toggle between those scenarios depending it is on a touch monitor or VR for performance sake depending on the output/equipment.
