how to setup oculus with arma 3

Its been a while since ive used my oculus which i have the DEV 1 and i cant figure out how to get it to work with Arma 3. I have Vorpx and the trial of tridef 3D and i downloaded facetracknoir cause it used to have rift option but now its not there. So if anyone can help me out that would be awesome.

Im not very tech savvy
