Valve Index. The trigger issue was in the demo but I was able to play the Prologue. Unfortunately, I wanted to mention that teleport doesn't seem to work (or I can't figure out how to do it) and the game is making me really nauseous. I'd recommend trying to emulate Until You Fall. For whatever reason, that game doesn't cause me any problems with sickness even though it has a similar movement scheme.
Thanks for the answer.
Unfortunately we still can't get our hands on a Valve Index to test. We'll make sure that everything works as intended when we manage to get one.
The teleport problem could also be related to the Index controllers.
We'll check out Until You Fall and see if we can improve the regular locomotion too.
Wow, I didn't expect such a humble and informative response. A free product that has a similar anti-nausea technique to Until You Fall is Google Earth, which you can download from steam. I hope you're able to get an Index to develop on soon, and I'm looking forward to see what you do with Iragon. Good luck!
