Without reading the entire thread and looking at the overall thing you’re wanting to do, I would haphazard to guess that as long as you don’t have anything too complicated as far as “gameplay”, such as AI, player-npc combat, other graphic intensive stuff, then this should be doable as long as you don’t go overboard. The entire thing is that with VR, you would typically want to minimize the amount of particle effects / post processing due to the nature of VR needing to be 75-90 fps to match the refresh rate of the screen (and to avoid nausea).
This is one of those “test it out” because afaik, there are some effects that are not yet hashed out for rendering in VR.
