ID Matte (PB only)


    This effect isolates elements in a 3D channel image. Many 3D programs tag each element in a scene with a unique Object ID. After Effects uses this information to create a matte that excludes everything in the scene except the element you want. Identify each object's ID by applying the ID Matte effect and then clicking different parts of the image in the Composition window as you watch the Info palette. You can isolate objects based on their Material ID as well. Select Use Coverage to create a cleaner matte by removing the color stored behind object.
