Hi, I've got an almost complete project. There's only one UI element in the form of a Start button on the home screen. Yesterday, I downloaded Gaze UI from the asset store and got it working with no problems for my Start button during play test in Unity editor. Assuming that the start button issue was resolved, I paid it no further attention. In the editor play mode, looking at start gets a reticle to light up as expected, hold the gaze long enough and the next scene is triggered. In build, the gaze reticle is just a dot, the activation graphic reticle fails to appear, and needless to say, the damn thing doesn't start. I've looked for answers and not seen anything that seems to give a meaningful solution (unless looking at forum posts from 2017 and people talking about Java script solutions applies) My build is in Unity 2020.3, so I'd be very keen to hear some current advice. (Yes, already mailed the guy who wrote the add-on) Project deadline was 14:00 today and I missed it.
