View Full Version : Insect Eye

Hi everyone ... thanks for clicking...
I'm currently working on a model of a horniss (I think that's the english word - but you could also call it "Killa Bee" :cool: - I'll post it l8er)
Now when it comes to texturing the eye I have a few questions. I want it to look very realistic (doh!) - even in very close closeups. Insect eyes however are very detailed - the way I did it now is just create high resolution spheres (deforming them a bit) and use the facette mode (3dsmax) for texturing. It looks a bit cartoonish though ... I put spot lights in front of them, too ... excluding all other objects.
Oh well I'm getting lost in my explanation ...
If you have made experience with this, it would be great of you to share some knowledge ... or are there any good tutorials on this? Which shaders are best? How should I do the lightning? How many specular lights? I want it to look a bit "wet", too. And do I need reflection maps for realism in here?
thanks for reading
thanks for replying

Yes, eyes are rather reflective, so you really will need to set up some kind of reflection map ;) Setting up sotlights which only work with the eyes will result most likely in an unrealistic look in the end.
Ummm... it's a bit tricky giving advice without seeing what you have done so far - won't you please post a render of the eye so we can see what you have done, and therefore give the best advice? :D
BTW I think the name you are looking for is hornet?

cool ... what a quick reply =)
on this pic I used a multi-layerd shader and discarded the spot lights.

BTW ... I'll stick with "Killa-Bee" :D

Here are some kinda icky reference pics of insect eyes:
Last year at work we had to make a photorealistic mosquito, and what we did for the eyes was we actually modelled the eye with all those bumps in it. Although this obviously resulted in a high poly count, it looked the best ;)
We did try and make it with bump maps first, but the actual geometry looked much better.
If you look at a lot of colour reference photos, incsect eyes often have a weird rainbowish look to them, which you can set up using incidence angle gradients.
You haven't mentioned which software you are using, but this is very easy to set up in LW.
Now that I look at these pics, it doesn't seem that insect eyes are particularly reflective - well, definitely not as reflective as human and animal eyes, in any case.
I think what will really do the trick is if you manage to set up that rainbow look - using mostly shades of green and black ;)
If you need me to explain how to do that, I can :)
BTW - killa bee is cooler :cool:

huiiiiii ... thanks for those cool pics.
I was thinking about modeling the detail at first ... and now I will go on doing this ... For this model I'm using 3dsmax and I think I'll be all right setting up a color gradient *g* ... but thanks for the hint.
I'll post the result later on (hopefully today).

Thanks, Leigh... I was searching for pics like that. :thumbsup:
And Marley, try adding a falloff map in the diffuse (color) slot, and adjust the colors a bit, so you would get something like in the image:
... it livens the image a bit + makes it look more realistic.
Effects like this happen when light is refracted inside the eye of an insect.
