Sorry man, it looks like P3DHack is still researching how to do this in VR. Here is a quote from one of the P3DHack VR developers: "
We want to try ourselves in VR Beta, but we need volunteers with VR equipment
If you want to take part, write here please"
To see the entire conversation just google P3DHack VR and it is the first link that comes up. Your best bet would be to ask them if you could be a tester for their new P3DHack VR Beta. They will give you the files, if they are still testing that is. Good luck!
