Eyes can be tricky. The easiest way to sculpt eyes is by using primative spheres or the pre built eyes as eyeballs and then sculpting around the eyes.
However I prefer to sculpt eyes as an exercise to help my ability to sculpt tricky areas.
1. Eye balls are sphere’s they’re smaller than you may think, on a realistic face they’re about the size of golf balls.
Eyeballs sit up and under the protection of the brow.
To sculpt holoow out the eye socket and then build up the spherical shape with the wax brush. Smooth is back and check from the profile and below to see if it’s spherical.
2. Add the top lid and bottom with the wax, thinking of a nice almond shape. The top lid generally overlaps the bottom lid. The lids may come high/low but generally meet the corners of the eye.
On older people we can see eye bags which droop down from the corners as well.
Check the eye lids from the side and below.
From the side we should see a clear v where the lids meet the eye ball. the inside of the eye should be back and hidden in the profile.
From beneath the eye should be very circular.
3. The eye lids should make a simple shape where they meet the eyeball. The upper inside edge can be slightly higher and the lower outer edge can be slightly lower. Note the shape of the lids change depending on where the eye ball is looking.
4. The tear duct is like a circular like shape that is on the inside eye low so that tears can drain out of the eye.
5. The brow sometimes dips down to overlap the outer edge of the eye on some faces.
6. Create the iris with the wax tool, be gentle. We can mask the area with freeze and invert (shift i)
This iris can have white below but generally not above unless the character has a very surprised expression, though this can be broken with very cartoony eyes.
7. The pupil can be hollowed deeply into the eyeball, this is a sculpting trick but also mimics how eyes actually work. We should see the full circle of the pupil otherwise the character will look sleepy.
8. Use the pinch and sculpt (vwrinkle_vdm) to sharpen the edges. Go up another level to get detail in the eye.
