  • How can you move a layer/object but keep the mask still?

    Posted by Josh Rod on August 16, 2016 at 7:09 pm

    I got a shape that i want to appear from a mask. But when i move the shape the mask moves with it.
    I could just use another shape that matches the colour of the background. But using masks would be so much easy and less layered.

    pls help this should be so simple. Alot of the tutorials are quite old so i thought of asking again.

    Put the mask on a second layer and use it as a track matte.

    Hi. Yes, make a white solid and paste your mask (make sure the white solid is above your other layer). In your comp panel on the right of the layer name you should see parent/mode/TrkMat(for track matte), under TrkMat you should set the dropdown to Luma. This means that only where the white is will any image appear. If you can’t see TrkMat heading press the Toggle Switches button on the bottom of the panel. Track Mattes are really useful and worth learning a bit about.

    You could also use the pan behind tool.
