I am trying to make a clipping mask for a mtn illustration I am working on. I am trying to get snow to cover the tops.
I understand masks in Photoshop, but when I am working in illustrator, I am having some trouble. I think it is because my mountain is a group that contains two shapes. I tried a basic example with two shapes no groups and worked great
I used: http://help.adobe.com/en_US/illustrator/cs/using/WS714a382cdf7d304e7e07d0100196cbc5f-644aa.html
Any ideas on what I can do, my AI file is attached? What is the best way to make a mask with having a group.
