I've been doing some rotoscoping and put in several hours animating the mask only to realize that I'm not in the project that the rotoscoping is designed for. Is there any way to copy an animated layer mask from one project into another?
Save the project with new name. Open correct project and import the roto project. Copy over the layer to the correct comp and reduce the project down. Save as new name.
Thank you. Just from the curiosity, why saving a final project under a new name?
Not necessary, but good practice. Since project files are usually really small, I have lots of different versions... In case something got messed up...
