keeping an eye on SLA

[ThirdEye]

Ultra... Hypercool, thanks :applause:

[turx]

this shader is wonderful. thanks a lot squidinc!

[nhytro]

Argh... the eyes are so good that it hurts,
Squidinc, it took me days to figure out how to get proper cartoon eyes done in cinema, I never knew it could be done easier, I used image maps and 2 pieces of geometry for mine. Thanks for sharing.

Hey squid thanks, its funny, I've been harassing Pal Everett into making a shader jsut for eyes based of the Pixar ones, and here you have done it for SLA, needs some tweaking still, but man what a beautiful job, I"m going to play with them and seee what I can do. I have some nice highres pxar images to match them up to if you want.

There was actually a very long thread about making procedural pixar like eyes, and I don't think any were as succesful as this. Brilliant work

cheers kaiskai :), post those images if you've got the webspace, unless they're REALLY big :D

if you make any cool changes post a link to the updated c4d file :thumbsup:
I was thinking of trying to get all the shaders to work in a sla fusion channel, using masks etc, that could get messy though if you wanted to change colours or pupil dilation

[LucentDreams]

yeah agreed. Man this shader with a shader tree would be awesome, you could control the pupil dilation with the brightness of the environment and such.

I'll make sure to post anything.

hmmm I think this is a prime example of why we should have a shader thread I think. I will set one up later today. Just have to get some of my own shaders organised.

[AdamT]

FYI, Darktree has some very good eye shader presets that can be controled with sliders. Unfortunately it's only the PC and it seems like it's not getting along at all well with R8.1.

[LucentDreams]

yeah the only reason I goit darktree was for the eye, but man darktree is not sitting well with C4d's stomach, so I scrapped it

[lildragon]

:bowdown:

[squidinc]

darktree is why I attempted this in the first place, I used the eye shader on one of my characters, I had to reinstall c4d and plugins not long ago, and for some reason I lost all the settings I'd changed for the eye colour, dilation , so I figured I'd make my own, cos I aint setting up dark tree shaders from scratch every time I re-install c4d :D

[medula]

Squid,

Thanks! Very nice of you! :buttrock:

[prayas]

Hey squid thanx a lot for this one! Maybe i'll take out the two bottles of cold beer and you just come over and tell me more of these real cool things on SLA :) :) :)

[pit]

Thanks, Squid - most impressive!

[the vapor]

Thanks Squidinc, these are lovely. Is it cool to use them in commercial work?

[manlio]

Thanks Squid for sharing your knowledge!

yeah sure, they're only shaders:)

[artemesia66]

thanks, squid. those are great.

[flingster]

heh heh...cool work
i guess you've been reading the pixar eyes thread to...if not check it out....(farley posted a good eye...which he got to dilate through sla)

these are top results though....thank for sharing your work...we'll all benefit...:thumbsup:

[xeno]

squidinc!!!! i was just talking with my c4d teacher today about eyes made using only shaders...he said he would show me it was done, but of course, something came up so he didnt have any time...thanx for posting these, im gonna try em out right now!!

[smoke]

I'm new to C4D, still using the demo version until my full version comes in (hopefully this week). Can someone give me a quick explaintion on how to use this type of muilt-layered shader?
Any help would be great. Thanks in advance :)

[nhytro]

Hi Kaiskai, where is this thread that you mentioned?

Thanks

is this the one you mean't

[squidinc]

just resurecting this thread temporarily, I managed to get a half decent pupil dilation working with the shader, which has now been compacted down to two materials, a small anim can be seen herehere (http://www.btinternet.com/~squidinc/eye.avi)

c4d file can be downloaded here (http://www.m1k3.com/cgremote/eyec4dshaders.zip)

[JIII]

whew thanks man if you had not resserected this thing I never would have known it was here.

thanks dude.

[randyrives]

Thanks for the great shader!

[flingster]

squidinc: yeah you clever guy...nice touch bud...thanks for the file.
:thumbsup:

[LucentDreams]

Well it took me a while, Squid's updated version sure helped me in having to remake the shaders using C4d gradients as opposed to bhodinut gradients, special thanks to PA and NAAM for their help. I've left the file entirely open so you can all go through the expresso and figure out how it works and such, I tried to label the inputs and outputs clearly.
Included is a small low quality video I whipped out showing how to use it, hope its understandable, the encoding is really nice at the start, but it gets pretty bad by the end


Anyways, its fully using on target and slider, but there are two other targets and sliders for individual eye control as well. ENJOY :)

thanks kaiski. wondering what makes this forum great people? its things like this. Man thats cool, thanks a million Namm and sadie and squid and kai and everyone.

totally cool.

[wesware]

thanks for posting these eyes... they are great!

[xeno]

awesome stuff! glad i saw this one in time! u people are the best!

[I animate]

Any chance you could make these for 3D Max?

Great eyes! :applause:

[LucentDreams]

sure buy me studio max and a good procedural texture system for studio max (as I understood it max's procedural shaders are uhm pretty poor. That was from the old procedural vwersus painted discusion from leigh's one texture workshop. never tried them myself.)

[bobtronic]

Hi there,

Last night I tried to recreate squid's eyes without
SLA (using R6). The iris needs some though.
So here are they:

http://home.snafu.de/bobtronic/misc/eyes_r6.jpg

and the C4D file:
http://home.snafu.de/bobtronic/misc/eye_r6.zip

You will need the C++ SDK for 6.3 because it includes
some shaders I have used. You can download it at
PluginCafe.

happy rendering, Bob

[bobtronic]

Ok, I improved my eyes and now I am pretty
satisfied. They are now pretty close to Squid's
beautiful SLA eyes. I made a little tutorial for
the people without SLA. I analysed Squid's eyes
and looked what tools I have to obtain similar
results. You will need a gradient shader. I use
the powergradient from the 6.3 SDK.
So here is the tutorial:

- make two spheres (one for colors and bump, one for highlights)

- apply a stretched noise texture or shader to sphere1
- apply a gradient bumpmap to sphere1; this will give you the depth
http://home.snafu.de/bobtronic/eyes/02_gradient.jpg
http://home.snafu.de/bobtronic/eyes/04_iris_base.jpg

- now I add another noise texture to sphere1 to make the iris look more real
http://home.snafu.de/bobtronic/eyes/05_iris_noise.jpg

- apply an alphamap and some color to sphere1 to make the dark rim of the iris
http://home.snafu.de/bobtronic/eyes/03_alphamap.jpg
http://home.snafu.de/bobtronic/eyes/06_iris_rim.jpg

- apply an alphamap and a gradient frompink to white to sphere1 to make the
skin of the eye
http://home.snafu.de/bobtronic/eyes/07_eye_skin.jpg

- apply an alphamap and some color to sphere1 to make the rim of the pupil
http://home.snafu.de/bobtronic/eyes/08_pupil_rim.jpg

- apply an alphamap (I sound like a broken record) and black color to sphere1
to make the pupil
http://home.snafu.de/bobtronic/eyes/09_pupil.jpg

- now the last step; apply an transparent and highly specular material to sphere2
to make the highlights. I choose a very small falloff and a great high to avoid a
plastic look. Voila you made it.
http://home.snafu.de/bobtronic/eyes/10_highlights.jpg

Another tip is to add the bumpgradient to each layer except the
highlight and eyeskin one to give even more depth. The tricky part are the gradients and
alphamap to make fit correct. One thing I don't want to hide: there are
circumstances in which the eyes don't look good, for example with only
a direct light. But if you are make portrait you can easily adjust the lighting.
And I noted even in animations no really disturbing quirks.

hope this helps someone


Bob

I've updated these a little, as when I tried to use them this evening I noticed they had gone a little weird with the 8.2 update, ( link on first page )

[sanfranguy]

What part of North Wales are you from?

My folks back home live in Rhyl, i'm pretty sure you know it!

[BazC]

Wow! Thanks Bob, excellent work!

Yeah the bump has changed a bit in 8.2 and such I should have sent you a heads up I noticed that too.

I'm 3 miles away :D, I hardly ever go there anymore though.
