Guided mask Path? Can you make it uncover?

Hello All,
I understand masks and guided paths… But I am trying to find out if I can create a more complex scene where after the mask “rolls” over an image it makes the image remain… See I’m trying to create the illusion that an orchid is growing…
Would I have to add action script to direct the movie clip???
I can’t find any code in my actionscript book that helps.

So if anyone knows of a site or has created a similiar animation I WOULD be VERY Grateful
:slight_smile:
Thanks ahead for any pointers
