i also need help on those eyes! i just cant get them to look convincing!

Hi
 

Hi Syrogen

There is a great head tut in the book INSIDE LIGHTWAVE 7 by Dan Ablan,
I am not very good at modeling heads myself:p,
but texturing the head could take you half way in making it look realistic.

Regards,

Dae:)

I'll go over the texturing part in the basic head tutorial.
But on the model I might suggest to sharpen his jawline a bit and maybe have a second look at the lips and nose. There's nothing really *wrong* about your model, only I think some more detail and characterization would do wonders here.

Very good start!

yes it looks VERY good to me too ! i guess you didn't use radiosity (or HDRI lightning) if you want a quick and easy way to lit your model, consider using a HDR image as an environment.
did you use sss ? it seems to me, that you did.
good work !

dea: thanks :) ive been planning to get that book, and also this lightwave 7 lighting book

philip: yeah, i plan to give him some sort of facial expression, just for more character.

RiGLEY: hmm, ive tried radiosity and hdri... but when i try to use them both together this is what i get

!! freaky aint it? my sample rate is at 4x12 and shading noise reduction is also checked... :(

Ugh... looks like a really bad case of exzcema... :)

hehe, all the fancy face creams in the world would never itch his itch

go to the image editor and apply a blur filter to the HDRI, render again
(make it real blurry, like size set to 10 or something)

hmm... still a no-go, doesnt work for me. i blurred horizontally and vertically at size 10 and it still was very... grainy

I did a model of my son based on the Inside LW7 book and at one point it looked really similar to your 'over-exposed' version, all I can remember is that I found the solution somewhere in the middle between too much texture and looking like a porcelain doll. I hope you have the ambient light off or virtually off.
I hate to tell you to twiddle with the knobs... but that's what I do. Good luck

here's the pic of my son... (I hope)

updated the color and bump maps....

just messing around with lighting

Looking good
 

The model is really coming together, keep at it.

Dae:)

2nd attempt!!!!!

looks damn good for 2 attempts!!

awesome dude

Awesome model so far.... I feel that some of the HDRI's lighting is too intense... Have you taken your light intensity down to 0-5% ? I find it works wonders.... http://forum.simplylightwave.com/sho...5&pagenumber=2 the last image on the page has a light intesity of 0 and I think it's on the right track....

thanks for your help everyone!

but i still need help with those eyeballs! i just cant get em right :(

Check out the head modelling tutorial in the Inside Lightwave book. There's an excellent guide to creating realistic looking eyes in there...

doh, i really need to get that book. i have the basic structure of the eye (cronea, iris) and yes i did make the iris flat, but i guess ill just have to fiddle with it

The tutorial in the Inside LW book suggests the following steps:

• Make the eye a perfect sphere. (Make sure that the sphere is rotated so that the 3 point polys face out along the Z axis)
• Clone the sphere and smooth scale it up slightly to make the cornea
• Select the first two bands of polygons in the cornea and smooth shift them with an offset of zero.
• Now move them out slightly on the Z axis and size them down to about 80% of the original.
• Delselect the polys and Knife through the third row back to add definition to the bump in the cornea.
• To make the iris, merge the first two bands of polygons on the inner sphere.
• Perform a series of 5/6 bevels to get a nice smooth inset curve on the iris.
• Delete the final polygon (pupil)
• Make a perfectly black disc inside the eyeball behind the pupil and size it up so that you can't see behind it when looking at acute angles to the pupil - this helps to add some depth to centre of the eye.

Hope this helps

thanks mark! i updated the eyes and the light setup

Really starting to come together now...

I'd suggest maybe a little less reflectance on the cornea and maybe a very slight bump (try crumple or dented) on there too to make the eyes look a little less glassy...

One more comment about the eyes. The whites of the eyes look a bit too white, unnaturally white and too uniform in color. I'm not sure how to tell you how to fix it, since you are further along than I could ever hope to be. Just a suggestion. But overall, it looks very good. Love the improvment in the pupil and iris.

I agree, if you look closely at your own eyes in a mirror, you'll see that at the corners of our eyes blend from white to redish/pink from the blood vessels in our eyes.
You can easily mimic that with a simple texture map.
Here's an example.
I'm sure someone probably has a better way of explaining it.


By the way your eyes put mine to shame. Great job!

thanks people! ive updated the eyes once again :P

Excellent - looking much better.

This just keeps getting better!..The eyes seem a bit luminous.. the eye in shadow seems as bright as the one in light....But the eyes are much better!!!!keep it up.

thanks! the eyes seem luminous becuase i have a light only affecting the eyes. ill fix it :P

woo, what a week. thanks mark for pushing me over the edge... i was really considering buying inside lw7, and you just made me do it! after reading chapter 10, i saw some flaws in my character, so its time to tweak the modeling and retexture, and relight my image. back to square one (almost ;) )

Syrogen - no problem. I find the inside LW book invaluable.
