Alright, I am relatively new to AE. I'm working on a video where I need to replace the eyeball on a cyclops mask. I have figured out how to replace the eye and I've tracked it to the mask itself which looks really good. But the thing I don't like is that the eye is just stagnant and looks sort of dead. As I have studied and watched other eyes I've noticed that eyes are never completely still they are always wiggling a little bit even when they're staring straight forward. Is there some sort of preset or expression I can write to cause this slight wiggle. I just want to breathe a little bit of life into this eye.
I'm NOT looking for big movements like left to right or up and down. I know how to do those. I just a bunch of subtle little random movements that I don't have to make by creating an individual node for each movement.
Apply a "wiggler" expression to the rotation? Also, the iris would be constantly opening and closing a little; that could be faked with a wiggler on the scale of the iris layer (if the eye comp had one, that is)
In each case, we're talking very subtle amounts of variation.
