  • Attatching a mask point to another layers position?

    Posted by Göran Thorén on October 20, 2013 at 3:38 pm

    Hi all!

    Is this possible at all?

    What I’m trying to achieve is to use the stroke effect and have the end of the stoke follow the edge of another layer.

    Thank’s for any input on this!

    Hi Göran,

    If the mask is simply a line that you want the start and end moving with another layer, then go to Effect>Generate>Beam, and pickwhip the start or end point to your other layer.

    If it’s a mask you need because it is a complex shape, I am not sure, but I will keep looking.

    Hope this helps!

    Christopher Green has some handy scripts for attaching mask vertices to things:
