Creating realistic eyes in Zbrush and Maya. Mentalray render video.

Okay, I haven’t been updating this blog for quite a while, but that doesn’t mean that I haven’t been doing anything. I have actually been busy doing tonnes of characters for Going live project and have been documenting all my progress of my Major project.

I have enough materials for 10 posts already, I guess. Okay. Let’s start where we last dropped off. After I’ve done texturing skin I decided to give my character really expressive eyes, that would draw attention, would be quite realistic and vivid.

So I have studied the structure of the eye and read tonnes of materials how to make the realistic eye.

I made an eye in Maya and replicated all 3 layers of the eyes that are visible from the outside. These are the cornea, pupil and iris, In Maya, they were represented by 3 different models and looked like that.

I made a dent on the outer sphere representing iris and sent it to Zbrush where I used radial symmetry to and drew the structure of the iris.

This is how it looked like in ZBrush. After poly painting and creating all these dents imitating the iris I have exported normal and texture maps and exported it back to Maya.

Then I’ve tweaked the texture map in Photoshop adding detail and realism to its colour.

Then I was playing around with different render settings.Realistic eye creation 11.jpg

Finally, I had the result that I was okay with:

This is what the UV of the eye’s look like:

Note that UV of the back of the eye, that we don’t see is super small, so I don’t waste the valuable texture space and can put more details to the frontal side of the eye.

I have been recording the whole process, and also I animated the eye in the end and rendered it in Mentalray to test how it would look like, here’s what I came up with:
