I've been through a number of posts on the subject of layering, but still can't seem to make this work.
As a test, I'm using the Checkers example -- I've added a UI Camera to the scene and set the canvas to Screen Space Camera; I've then added a black background behind the Panel containing the instructions. The effect I'm after is that a touch that begins on that panel should not be able to rotate the checkerboard.
I've tried a variety of layer types and rearrangements in the TouchManager, but nothing seems to work as intended. How would you set it up?
