Alex, Thanks for your responding.
We are working on a 200 model using the Unity plugin. We have run the Stylus tracking test and it works fine. We are working in a room without much sunlight so I don’t think that is an issue. To more accurately describe the behavior, there is a periodic absence of tracking entirely. But the head tracking continues to work, no problems there. You mention that the problem may be attributed to a slow frame-rate, but wouldn’t that result in a delay between physical motion and the corresponding motion in-app? What would cause the periodic absence of tracking?
Thanks for your assistance!
