I'm using Illustrator CC, and have a tear-drop shaped object which has a gradient mesh applied to it. I need to use the pathfinder divide tool in combination with another simple shape to take a chunk out of the teardrop, but the pathfinder tools don't seem to have any effect on an object with gradient mesh applied. Am I missing something obvious, or is this not possible?
It is simply not possible to use any Pathfinder operation if an object contains a mesh.
You may be able to use a clipping mask or opacity mask to hide a portion of your teardrop rather than trying to remove a portion.
