I'm having some problems trying to morph a star icon into an X. The star icon is a stroke with no fill inside of it. I've tried having them both as a stroke and as a compound shape. Neither of which ends up with a good result. I've been copying the shape path keyframe from the X shape to the star icon, but when the x shape is a stroke it's obvouisly two paths. Is there som other ways to get around this?
