Ok, I have been searching high and low and nowhere does anyone mention that there are two different types of eyeballs (visibility icons) in after effects (one is the normal "positive eye with a highlight) but also there is this "negative version" that exists as well. What is the difference and what does it mean>???
THIS IS DRIVING ME INSANE!!!!
The "filled pupil" icon is used when the layer has a Transfer Mode, Preserve Underlying Transparency, or Track Matte set.
Mattes or blending modes.
