The basic eye settings involve adjusting the size and changing the textures of the eyes.
The recommended flow for adjusting the transform data of the eyeballs is as follows.
Zoom in to the eyes of the target actor.
Change the size by modifying the value in the Scale field. Do not worry if the eyeballs pop out. We will rectify this issue later.
Use the Narrow/Wide slider to adjust the distance between the two eyeballs.
Adjust their position by modifying the Move data.
The eyes' texture channels can be used to create various effects. Utilizing videos will create even more specific effects.
