Old model that I'm going to work on next week. Rendered with global il (ala Arnold style). Looks like clay eh ?

Wow, I really dig the light you used. That is honestly my most favorite kind of light source right there.
And yes, it does look like clay, very nice.

pretty cool. What program was this rendered in. 'Arnold' isn't out yet, right?... Just remember that global illumination doesn't make up for a bad model. Not that yours are bad at all, but I do think it looks a little a little flat. Try bringing the whole front of the face a little more forward. Though it might be because of the rendered angle. Some unwanted polymess around the eyes as well...Looking forward to the updates

Was this actually rendered with GI, or are you just trying to fake sky light?

Global illumination is the term applied to light that has bounced. Light from the sun is direct illumination, light that bounces off the ground and hits the bottom of an object is global illumination.

Here is an example of faked GI that I did about a year ago:



(Note how most of the scene is lit and shadowed by light bouncing off the wall and floor)

Your image isn't obviously demonstrating GI (at least, I don't see any secondary light strikes), its mimicking a parabolic area light.

Not trying to be annoying, just wanted to nip a misapplied term in the bud . . . all of the techniques that you see trying to fake the Arnold-look are only dealing with skylight . . . skylighting is a nice side effect of GI when your scene is inside a dome, but by itself, skylight is not global illumination.

Decent mesh BTW, aside from the artifacts. Is this a poly model?

Thanks Loki! . . . I think I'll post the full size one in its own thread, I don't want to clutter yoszi's.

Isric: Glad you like it. I like this sort of lightning as well.

Boomstick: I use the king of all 3d apps - Lightwave, eheh, every LW user says the same thing. Yea, but all those Arnold renderings brought my attention back to 3d. Flat - it could be, i'll keep that in mind once I start correcting the features.

Balistic: It's a dome setup, there's no secondary light. I used the global illumitation feature from LW. I suck at lighting, I found surprising what I got out of one sphere. Nice image, feel free to add anything you like. Yea, It's a poly model.

some old mama,

Its amazing how much a simple sky light can do for realistic skin tones. Nice.

I remember reading somewhere that LW's GI doesn't like intersecting geometry . . . maybe that's what's causing the artifacts under her bangs?

balistic: There's no antialiasing there only a post processing filter I used to reduce rendering time. Antialiasing would get ride of that. LW has beautiful renderer. This is the simples setup one could do, add lights, env and things will only get better.

Here's a test I did a while back of A:M's global illumination, in an attempt to fake HDRI lighting. There's no direct illumination, all the light is coming from the sky dome.

Its still got some kinks in it, but Hash's solution is pretty good.

Trancer: It looks realistic thanks to a photo i stuck on color channel and GI. It's not so hot without the two.
Modeling with combination of patches and sub-ds on a top of two sketches in bg should work well. First splines - rapid surface creation, Sub-ds - detail, sketches - right proportions from the start. I haven't tried that in depth yet - once i started practicing drawing i abandoned modeling entirely

Ooh! Cuz the facial hair is so realistic! Btw.. what does GI stand for?! You got ICQ?
Or MSN messenger?

And how could you stick a photo in GI (Global illumination?)

Ballistic....just a question on your clarification...

I was under the impression that GI (global illumination) was the effect you got when you faked light bouncing off of everywhere by adding a global light. One that hits every surface equally and adds to lighting. The lighting you are talking about I have only heard being called by the name of radiometric lighting, or radiosity. ie the effect of light boucing off of things that have been hit by light, or radiating light of the color that they reflct..

Radiosity is a subset of GI, though the terms often get used interchangably (or at least, they did before those Arnold renders started popping up ). Global illumination is any light that is not coming directly from its source. Radiosity is still about bounced light, but uses different computational methods to solve for it.

Light from the sky technically /is/ global illumination, because its not coming directly from the sun, but a lot of people are starting to think that's all GI is because of the Arnold renders.

They whack together an array of lights in a dome and say "Voila! Global illumination."

At work, I've been developing fast methods for faking sky light . . . my current record for one that looks good and renders fast is about eight minutes a frame for a medium- sized architectural model that's fully-textured. For the A:M renderer, that's damned speedy

But it ain't GI, not without secondary bounces.

Yoszi: That 'old mama' model is *extremely* nice... but she has NOTHING of an old lady as far as physical features(besides the fake white hair). Now, judging from the first post of your own model, which is coming along well, I don't beleive you actually modeled the girl's head -- I think you just slapped some white material on her hair and called her 'old'. Sorry to be accusing you of this Yoszi, but that's what I see. (The fact that you don't seem to know what facial characteristics an old woman has over a younger one makes this really stand out and shows that you're just making this up in my oppinion).

Frost: You got to be kidding. I can say that the model depicts a black madonna with horns during an epileptic dance and that should not matter at all. I made it and i;ll call it whatever i want. i'm not quite sure what you're getting at here?

In Viewpoint Premier Catalog 2001 edition, under publishing partners look for Michal Wolniak(that's my name) and see the corresponding meshes. YOu'll find the old mama among them. If there are any more doubts I'll get the catalog out of my closet and some proof of my identity with it. Just say a word.

Trancer: I have MSN messenger ([email protected]) I never used it thou.

Frost, I hold my tongue with great effort. I'll say that your post is insulting.

these are not polys, it's a controlling cage for subdivision the model was made from. If the model is not mine then where do you suppose i got that ?

Hmm, my apologies Yoszi, but no, I was not kidding. How can I say, it just looks, 'too nice' and too '3d-threnodized' at the same time. I was wrong, my sincere apologies.

Like I've mentioned, the first in-progress image you posted shows promise, but it is nothing like the finished 'old mama', I jumped to conclusions. The 'old mama' face is well modeled and well textured, while on the other hand the hair doesn't have any sort of proper material in comparison. It just seemed like a lame mesh rip by someone who just changed hair material and called it 'Old Mama'. Surely you must see how I could have come to such a conclusion, my bad.

I should have done a background check before writing that crap. But you, being a professional modeler who sells his models, I would have expected a more 'professional' and serious attitude towards naming the work you sell professionally (but hey, you're free to do what you want). All this put together can make your work authentically questionable, a trap I have fallen into, I hope you can see that. Steven Stahlberg, a person I respect very much, has a link to your site so I take it your real. =)

Anyway, enough excuses, I screwed up, and I apologize. Very nice work by the way, keep it up. =)

Now I feel stupid. =/

EDIT: Yeah, it's fine, one post would have done it. =) Sorry, I know how it hurts to have your work questioned.

Appology accepted, forget about it. I wouldn't call myself a professional modeler. I respect S.Stahlberg as well, it's hard not too if you're into 3d modeling. I never posted any 3d so that could look suspicious.
