I have created a similar file to the grass tutorial, and for some reason cannot mask it. It shows it is being masked on the stage, but when I preview the movie, it is unmasked. I would really appreciate some help. I can only think that maybe the actionscripts are the culprit, but I am not a strong enough scripter to know. thank you.
