As you can read in this update… Steam created SteamVr Input. An update that allows users to build binding configurations for any controller and for any game, exactly how they like it!!
Absolutely amazing. But it does state in the end of the announcement:
“Hardware developers should look at the driver API documentation[github.com] to see how they can enable this new system for their devices.”
It would be great if Pimax could do so @xunshu.
Then we could change button configurations on the fly for any vr game we want if needed.
