Just started using After Effects today. I've created a clock where the hands spin round but for half the clock the hour hand disappears. The face, and both hands are on separate layers and I can see the minute hand at all times. if I hide the clock face I can see the hour hand at all times. So I figure there must be something on the clock face layer that obscures the hour hand, but I can't work out what or how to get rid of this.
