I am trying to do the "Colored Eye" by JaffaCoder in distortions and Modifications but when I try to do the selection for the pupil my inner selection keeps disappearing (?): I am doing the first steps where to color the iris part without coloring the pupil the instructions say: Select the part of the eye you want to color, invert the selection, now select the pupil..." after I select the pupil I let go of the mouse button and my selection disappears... I have done this technique before but never had this problem.
Any help on how to fix this problem is greatly appreciated
