Well espresso works a bit different than after effects expression does, but I found a way to connect it all to a slider via user data thingy. So if anybody in the future need this, here is a printscreen of the setup.
Hello, So I have created a little character with 13 different mouth shapes, and I want to animate this in a stop motion way. By turning them on and off, now I can do this manually with every mouth shape, but I was wondering if there was an easier way to do this. In after effects you can turn on and off layers with a simple checkbox and add them all in the effects pannel. But is there a way to do this in Cinema 4D, ive looked at espresso, but I'm not familiar to with that.
