You can use the Edit Original command in After Effects to open a PSD file in Photoshop, make and save changes, and have those changes appear immediately in the movie that refers to the PSD source file. Even if you don’t use Edit Original, you can use the Reload Footage command to have After Effects refresh its layers to use the current version of the PSD file.
