When applying an appearance to a specific part or face, generally you just drag the appearance you want from the appearances menu onto the part and the Appearance Target Palette will show up, allowing the selection of where you want the appearance to be applied. This is no longer working for me. It displays a crossed out circle when I try to drag the appearance onto the part, and attempting to apply the appearance through editing the material simply applies it to the whole part instead of my selected area. Is there a menu option that got changed? How can I bring the Appearance Target Palette back?
