is it possible to make oculus based controllers based on the Oculus?
Yes Oculus has 2. Or 3 versions.
Otherwise not really as Oculus hasn’t opened up constellation to 3rdparties to make their controllers.
Latest Rift S is in a way a WMR style deisgn.
I have an oculus rift that with vr oculis steam recognizes me all but with the pimax only the pimax viewer
Oculus controllers are not usuable with other headsets. There is a kind of way but too much headache as you need as one commponet an og Rift headset connected.
so should I leave the oculus rift viewer connected together with the pimax
You’d need to google it. Try Oculus Touch with Vive.
