Random layer position constrained by another layer's alpha
by finder0 on Jan 6, 2008 at 3:43:54 am

I am trying to create a 2.5D landscape with several hundred layers randomly positioned all over the landscape. I see how to have the position be random, but is there a way to limit the positions to only within the "island" of the landscape as defined by its alpha channel? This is something simple to do with trapcode's particulate, but i need the shadows cast onto the ground and thats where trapcode is failing me.
thanks
