1. Create an object with a collider and an Udon script that uses the Interact event (hereby referred to as "button").
  2. Place the object behind a wall (mine's set to not render) with a collider. set the GameObject to the Ignore Raycast physics layer. (hereby referred to as "wall")
  3. On Desktop, attempt to click on the button with the wall in the way. Despite the wall's physics layer being set to Ignore Raycast, the Desktop Interaction Raycast does not ignore the collider.
