Hello:  
I,m using flash mx, and I,m trying to use the tutorial of this page “Falling Snow” in the Special Effects section.  
I want to know if its posible to set a mask for an specifict area of the image, because I dont want to show the snow in all the movie, only in an area.  
I don,t know so much of actionscript.  
Somebody can help me.  
Thanks in advance and sorry for my english.
