Keep the brush small to get get a crisp edge toward the center and you can lightly feather and blend out the outer edge with a larger brush size.

Take your time to mask out a shape you like based on your reference. Then to get the more complicated fibers and folds along the center we can draw out our shape as a mask to inflate and push up. Try doing it large then smoothing it a bit and adding more, mess around and see what looks good to you. Set your brush up with spray and the lines alpha. Activate Radial Symmetry from the Transform Menu. WeвЂ™ll create some fibers first which we can blur and add more and more on top giving a layered effect of fibers flowing inward.

Now we can divide up to get more resolution to sculpt the details of the Iris. Unhide the rest and Ctrl click the ball, blurring your selection so we can get a nice soft concaved IrisВ (press W and position action line from the side and translate it inward) Ctrl Clicking the Canvas masks all visible. Then by Ctrl+Shift Clicking the Iris we hide the rest. Now lets make a polygroup for the whole eye then one just of the Iris to make our selecting easier. First invert the mesh so its inside out, then youвЂ™ll use panel loops to extrude it and bevel the edge (check settings below) By inverting it first it extrude inward instead of outward, giving us depth and keeping the size and shape we had. Next we will use some tricky shit to give it thickness. Next you can use the ClipCurve brush to clip the eye from the side to flatten out the iris quickly. You can hide/unhide until you get the size you want. With our first sphere we will make the Inner eye model.В That will consist of making the pupil hole, defining the iris shape, and giving the model thickness.ДЇirst hide the polygons you want to delete to make the pupil hole. You can Hide one of them so we can focus on one at a time. Before we do anything else, duplicate this so we have the two identical starting spheres to work with. After making it a polymesh we are going to rotate it 90 degrees to get the topology flowing forwards which we will use to make the pupil hole and give us a nice edge flow for the shapes we will be making. In the tools pane select a sphere and make it a polymesh so we can work with it. We start with a sphere, which isnвЂ™t as straight as it could be.
