NVIDIA VR Funhouse editor is extremely slow and won't load correctly on Oculus Rift

I know this is an “old” free game, and maybe the editor is straight broken with it now but I’ve been trying to dip my toe into VR development.

I was following NVIDIA’s official tutorials on youtube and have noticed that trying to add anything new in blueprints takes a long time to bring up the menu when I right click. On top of that frustration when I go to test it I can’t choose a Play option because the arrow drop down won’t work and simply pressing play I only hear sound with the head set on.

Would anyone have any insight on this? Would the fact that Oculus, SteamVR, and UE4 having to all be open while modding be a good reason?

Appreciate any response, thanks!
