Subject: Cycles eye shaders


RobynsVeil ( ) posted Thu, 09 August 2012 at 5:07 PM · edited Wed, 27 November 2024 at 5:34 AM

I'm having a play with Antonia in Blender - she's very nice, willing to accomodate me even there. There are some really interesting solutions available for skin for Cycles even before we get an official SSS material (as we've seen other threads) but I haven't seen much for eyes.

Does anyone have any ideas for a Cycles-friendly eye shader?

Are you able to migrate the bone system of Antonia to Blender?  I'm thinking of moving Antonia to Blender too.

I dont believe so, Amy. I was planning on doing a re-rig using BlenRig. Just starting with materials atm, since i can always do the posing in Poser for now. Be happy to share anything I learn. I'm at work atm - and typing on my tablet, which is suboptimal - when when I get home I'll post a render and what I've got so far in terms of shader... it isn't much. :blink:

some nice info here on rigging RV

http://www.youtube.com/user/Terumag/videos?sort=dd&view=0&page=1

could just make your own "doll" I have just got one from makehuman into blender fully rigged an ready to go

ok does need a bit of tweaking but does pretty much work

ps HAD to get a recent build of blender AND a nightly build of makehuman to get the plugins to owrk right (and UNtick enforce version on import)

You can export Collada from poser, rename all bones in the skeleton and corresponding vertex groups according to the Blender naming convention (i.e., rHand should be hand.R and so on), then tweak the weight map and add control rig ("Humane rigging" as posted above by heddheld is an excellent resource on how to do just that provided you have basic familiarity with Blender).


RobynsVeil ( ) posted Fri, 10 August 2012 at 6:55 PM

Just going through the videos now, Hedd. As Whispers said, excellent resource: thanks heaps. 😄

@Whispers: where would you be doing the renaming of groups? I'm unfamiliar with Collada... is there some programme I need, or can I do this in a pure-text editor?

On to the 6th video in the series... tempted to get the DVD, if only to support Blender, but that ONE issue I have with video tutorials keeps coming up (well, there are issues).

Well, Two, really.
One is: they go too fast for this grey head and
Two: they click on stuff or use a shortcut and i have NO way of knowing how they brought up that dialogue because they fail to share it. :cursing:

So, what exactly was wrong with pdfs, again???? :blink:

There are so many different types of learn-methods: why do I have access to only this one just because most  people who make tutorial erroneously think it's the best way for everyone to learn stuff? it isn't.

Oh, bit of an aside: I've been having HUGE issues with unused images being stored with my .blends, which show up whenever I'm selecting an image, like the image above.

The way to get rid of that is - according to Disorder66 on the BlenderArtists.org forum - to:

-- Start a new, blank Blender file (one with nothing in it)
-- [Menu] File > Append [Shift F1]
-- Locate the file you want to clean up
-- Select the  "Scene" folder
-- Select "Scene" and click the "Link/Append Library" button (upper-right corner)

At the top of the interface, next to the File | Add |Render | Help menu is a box that allows you to select a scene. (you now have two 'scenes' in your .blend). Click the X next to "Scene", which will delete the Current Scene.
Now you'll have Scene.001 which is your original scene that should be clean of the image references.

If you still have images that persistently hang on:

-- create some mesh and create a material for it based on an image texture
-- select one of the files you want to get rid of from that dropdown list (shown above)
-- hold down the Shift key and click the X to the right of the number (and the F and the tiny file folder)

Do this for all the image you want to get rid of, delete that dummy mesh when you've finished and then save the .blend file with a new name. Repeat the steps above (by Disorder66).

couldnt find that thread on BA, but the way that usualy works for me is to make sure the image isnt being used, save the blend then open it again and there gone

a texture will only be saved if its not in use by clicking on the little F (fake user)


heddheld ( ) posted Sat, 11 August 2012 at 1:56 AM

just tried the collada! doesnt work from p7 (sorta knew that but tried anyway lol), do have a box for exporting rig but its greyed out an I couldnt get it to come on, one tip is when u save it out put it in its own folder!! it takes all the textures maps an dumps them with the dae, oh well desktop needed a tidy ;-)

 

the rigging videos, yeah I'm thinking of buying them too lol, but just watching them an getting a few tips helped me understand blenders rigging but I dont think I am capable of rigging quite like that yet (I have a post on the 'nook about make human into blender)

 

shortcuts!!!!! yeah I know how annoying that can be  on the other hand I am guilty of doing the same thing, they become so ingrained into your workflow you just do them on "autopilot", be even worse if I tried to do a tut now cos 12 shortcuts are mapped to my mouse lol, if you tell me which vid an where I might be able to tell you but he did get a few past me too

Well, I sort-of thought so too, Hedd, but those little buggers simply wouldn't disappear, no matter what I did. So, after much searching and combining methods, this is what I came up with. Hope it helps someone.

RobynsVeil: I mentioned that you need familiarity with blender which means knowing how to work in blender, keyboard shortcuts and whatnot. Otherwise, it's "a bit" confusing.

I recommend going through CG Cookie tutorials first. There is an in-depth introduction to Blender in 3dBuzz as well, but, while it's free, it requires registration and currently unavailable for streaming: you have to download and unpack archives with videos. CG Cookie is much more convenient and has rigging and animation tutorials (not nearly as in-depth as "Humane rigging", though).

As for vertex groups and bones, you can rename them in blender after importing the model.


RobynsVeil ( ) posted Sat, 11 August 2012 at 4:45 PM

Well, I am reasonably familiar with the hotkeys associated with modelling, just not rigging and animation.

However, I'll do as you suggest, Whispers... I'm also a CGCookie 'citizen', so hopefully there are tutorials on rigging I'll have access to, and that the tutorial author will mention the hotkey he or she presses...

 

(all of their tutorials are videos as well, I think) :blink:

Please don't get me wrong, Whispers: my remarks are by no means any reflection on the value of these tutorials or your recommendations. I have issues with video tutorials in general. It's just me. Videos tend to move at breakneck speed - to me - and other times tend to stutter when the videographer lost his place - to me - and are heaps larger to download, particularly if you have limited internet bandwidth, which is not a problem for me, but there are still a lot of people on dialup for whom this is an issue. I wouldn't so mind it if videos were only half of existing tutorials out there, but all the current stuff appears - to me - to be video-based.

Which what I really appreciate about Andrew Price: he at least realises that people have different approaches to learning and does use a more multimedia approach to his tutorials. Which makes his Nature Academy totally worth every penny I paid for it.

OKAY!

Back to this tutorial :lol: right atm, doing the bouncing ball (and taking notes)... :biggrin:

Still mucking around with materials. I sort-of think we're going to have to go with painted-on brows: that geometry casts a shadow in Cycles, and so it all sort-of looks wrong.

Open to ideas... so far, I have the above shader for lashes, which works a treat, but there's nothing in proximity to conflict with, whereas with brows...

Oh, and the first attempt at an eye shader: seriously nothing spectacular. :blink:
