Source Well

Many effects in Motion apply specific parameters from one object to another. For example, the Bump Map filter applies texture from object A to object B. The Orbit Around behavior causes object C to circle around object D. You set these object relationships using a control known as a source well (sometimes called an Image well). A source well is an empty box into which you drag a source object to influence a target object.

To use a source well
  • Drag an object from the File Browser, Library, Layers list, or Media list into the empty box.

    The name and a thumbnail of the source object appears in the well and is used as a source for the effect.

To replace the contents of a source well
  • Drag an object onto the well.

    The old source is replaced with the new one.

To clear a source well
  • Drag the icon in the well out.

    The well is emptied.
