hi thanks! It's enlightening to hear your comment regarding OS, will keep a note of that as a vr content developer.
Havent tried it but there's a (dev) Linux port for SteamVR, UE4 runs on Linux as well and most UE code as long as they are kept platform independent (which this game is) should "just run" in linux coz of UE4, so technically no hindrance or difference in development from what I live streamed except of course not using Visual Studio for the C++ coding part and yeah setting up a rig for it as not sure how good a VM would handle VR.
But very good point, will need to consider this for future projects ;)
