I've been having the marvelous experience of a lot of things clicking into place for me over the last week or so in C4D. Here's one product of some of my experiments: a procedural shader for an eye. About an hour's worth of tinkering.

Best,
Andrew

That came out great.
Best eye shader i've seen thus far.:)

I like more: can u share the file? ;)

Very nice - and clever. A couple of minor suggestions, partly because it looks too perfect. Sometime the iris has small black dots in it, (at least mine does, maybe I should see a doctor?). Also the iris is not just one colour but a blend of brown, yellow, blue, grey etc. The veins on the eyeball are nice, (cranal?) but not very realistic. It would be nice to have a procedural that did good branching veins, I guess some sort of fractal, but I don't think there is one, so your compromise is probably the best option.

Very nice, here's some inspiration for you, they come from Julian Jeremy Johnson Mortimer's website, all done with procedurals (Maya):

biggest thing your missing that Julian has is tha shadow under the specular in the iris. you need a seperate specular object to do this.

Very nice, and pretty damn realistic for something procedural. A good template for experimentation, maybe we should all have a go based on your template there, and we can post our results? Have a nice eye shader repository? :)

then I'd have to reconnect all the wires on mine so it was animatable and easy to control, I'll keep my eyes as is.

Thanks for the feedback and pointers, everyone; not to mention the kind words. :)

I was doing that first attempt at work on the R9 demo, so I couldn't save the file (Sorry MrBraun, but I'll consider doing a tutorial when I have some time :)). But I got home last night and started again, this time using separate geometry for the cornea. Also added the noise to the iris, per basilisk's suggestion, and did a lot of further tweaking to and experimenting with the original idea.

Unfortunately, using a transparent cornea seems to force a big hit on the render time, which is starting to make this exercise more tedious than fun (as is the lack of a shader tree). I think what I have is sufficient for my original purpose -- a character still -- so I'll leave it at that.

All that said, I think I'm going to have to jump on to the give-us-a-shader-tree-in-R10-or-better-yet-R9.2. :D

Best,
Andrew

hmmm ...
im wondering no one has posted this in cgtalk (or has somone? if yes, sorry)
here you go with a shader tree in c4d:
link (http://www.3d-worxx.com/forum/thread.php?threadid=12247) (treeview 1.0 by affa)
Itīs a shader Tree-view (with Images) and its great.
(I dont know Maya or other application, but now i know why a tree-view was so important)

best regards

Jan

btw: great looking eye ! i really like it!

Thanks for the tip, Jan. Unfortunately, I can't seem to get the plugin to work. I put i both in the plugins folder, as well as t's own sub folder, but it doesn't seem to show up. Where do you access Treeview mode?

While Treeview looks like it would be helpful, I long for the possibility of a built-in tree-based shader system (though Dark Tree (http://www.darksim.com/html/darktree25.html) looks like it might be a viable alternative, if not a superior one; I think I'd need to be able to make a business case for it first).

This (http://www.scifi-meshes.com/forums/showthread.php?t=23048) is what really got me fired up lately about procedural shaders. :) I think C4D's current implementation would be to cumbersome to get results like in that thread.

btw: great looking eye ! i really like it!

Thank you. :)

Best,
Andrew

I have put the .cdl file in a folder called "treeview" in the pluginfolder.
(i think you can call it what you want, but who knows)

it shows up in the pluginlist, in the top-plunginmenu (not in shaders or something).
(i thnk it only works in 9.1 )

To show what this Plug can do (better to say " show ") :

here a screenshot:

Many thanks to affa :-)
What a great helpful Plugin!

Great job. I haven't really played around with procedural textures in C4D. Do you know of any good tutorials I could look at to get a foundation?

Works over here. R9.1
Thanks, great and handy plugin.

Peace,

Silly question, of course there is a need for this plug-in on the Mac.

How do we contact him?

Is there something news about the eyeshader?
Maybe a file to download :-)

Its looks like a great shader.
Maybe a radial disortion of iris, yet.

Just curious about how treeview works. Could you, for instance set up a procedural noise once to drive several channels, say color, bump, and specular color for instance?

Hi there, just found this thread ;)
Nice that you like my plugin :D
The plugin is just for displaying the current shadertree, there are no possibilities to create instances,

greets,

Um... well, I just landed here, after I recieved two mails of people wanting to see a mac version of treeview.
Well... since affa already posted here, I just want to add, that I'm not affa ;) And I just posted the plugIn in our forum, because he asked me to. So please don't send your requests to him, and not to stephan@3d-worxx.com ;) Good luck with a mac version...

BTW: When did we talk, kevinb? :scream:

great shader!!

But can someone post how to do this same thing in mental ray (softimage XSi or MAYA)

Thanks in Advance
