  • linear wipe and shape layer

    Posted by Ilya Sire on March 30, 2021 at 3:21 am

    Hello forum,

    I have a shape layer and linear wipe with any % completion. How can i make it stick wherever i move the shape layer? For example i set at 50% completion and move shape layer somewhere, it still wipe half of my shape layer.

    Using a solid layer should be no issue of this.

    Thx forum

    I found other example in forum and play with it, it worked if shape layer is center of comp. Please take a look attachment. This comp conversion makes me really lost. Any help?

    Thanks for your hacks Trent Armstrong, it worked, but I’m looking 1 layer solutions, I spent a few hours on this with no luck. ?

    this s=((p[1]/2-(hei/2))/height)*100; drive me crazy.

    For Shape Layers and Text, the effects are applied based on 100% of the width and the height of the comp. So anything you try to do will have to be based on that. The big problem with trying to use a Linear Wipe isn’t the percent of the wipe, it’s the angle because it always defaults to rotating around the “center” of the layer. With the effects used on Shape Layer always fitting themselves to the full width and height of the comp, the center for Linear wipe is always at the center of the comp.

    If you need a single layer for this, take what I built there and move the Rectangle 2 from the MATTE down into the Content of the original shape. At that point you can use Merge Paths to get the reveal you’re looking for.
