How do I do a realistic Eye?

manilamerc

Hey guys I'm a noob at doing eyes and my school didn't really teach me about doing eyes. the way I did them were quite noobish. I modelled it just by adding a sphere



then I textured it here's my uv layout





and now my character looks weird




Can someone tell me how to do proper eyes?

Ben Mathis has an article over next gen eyes.

Eyes are not so hard to model. Most people do the same thing you did. But now technology has advanced and a lot of times people model in the iris as well as the cornea.

There are a few very good threads on the forums if you do a search, too.

It would also probably help if you actually centered the pupil+iris...

This thread also talks a bit more about Ben's eye tutorial.

To be honest the eyes are not the ones making your character look weird at the moment. You have some really weird shading going on, especially on the nose and ears. Normal map issue perhaps?

well I'm using the 3ds max viewport so it tends to show up like this, but when I put lights on and render it the weird shading goes away

Right now you have specular highlights in the diffuse map (your diffuse map should not have directional lighting info) and you are only using diffuse shading.

Find a good reference of an eye and try to mimic the specularity and the shading in your material setup. Keep in mind that not only are eyes somewhat reflective, but they also have subsurface scattering. In order to integrate the eye into the head (so it looks like it's in the socket and part of the head) you need to account for the ambient occlusion. I believe ways of doing that are described in the link above.

Before any of that though you need to figure out why you're getting that weird shading...

as I have said above, the 3dsmax viewport show up like this. But when I put lights to render it the weird shading disappears

That's nice, but your EYE TEXTURE has specular baked into the diffuse map. No rendering feature in Max is going to change the texture you showed us.

the nasty lighting is probably Max using the 2 point default light setup, which sucks a cubic fuckweight of dicks.

And that's my phrase of the day.
