Detect if a specific face landmark is visible
Is there a way to use a custom trigger only if a specific face landmark is visible? I would like to make an 3d object hidden if some face landmarks (say the ears, nose or mouth that I could specify by their number) are hidden by a hand, cloth or anything.
I tried using the behavior script, but it is not specific enough for my needs.
Is it possible? If yes then how can I implement it?
