my character has just little circles as eyes. No eyebrows, no pupils, just two little circles. but he can look angry. I've seen that you can change things with the keyboard, in my case from little circles to diagonal elippses. But how? What is the correct term for the eyes? Can i change both eyes with one klick?
It sounds like what you want are 2 triggers in a swap set.
The Chloe example puppets have a few of these (for switching between hands, eyebrows, and blinking). Basically you add the layers/groups you want to show or hide together into a trigger and then add those triggers into a swap set, pick one to be the default, and then assign a key binding to trigger the alternate.
Those triggers can also be added to the Controls panel so they can be clicked.
Yes, that's it! Thank you again! And I'm using only the righteye layer for both eyes, so I can swap much easier.
