Step By Step

MAKE A realistic eye

01 cornea Modelling the And the iris

Select the Sclera, mask out the iris and push it in with the Move tool, creating an inverse dome. Mask out the pupil, remove those polygons and extend the edges towards the centre of the eye. Unhide the Cornea, mask the same area as for the iris and push it out, making a smooth dome.

03 Paint the eye

With the base structure sorted, it’s time to add some colour and finer detail. Use mask by cavity to add extra depth when painting the iris. Draw more colourful fibres and blend them out around the edge of the iris. To add veins, cover most of the white with a red mist, and then drag out vein alphas.

02 Sculpt the iris

Using Standard and Dam Standard brushes, begin sculpting fibres from the pupil towards the outer edge of the iris. The aim is to make them resemble a muscle. Mask out a pattern with the radial symmetry, then edit it according to how you want it to look. Pull out the shape and then smooth it out a little.

04 final touches

Export the eye model to Keyshot. Apply glass material to the cornea and enable two-sided refractions. No refractions would make it look as though there was an empty space between the iris and the cornea. If needed, go back to Zbrush and tweak the eye until you reach the desired look.
