A problem with shadow contrast

[ThirdEye]

No ideas? :shrug:

[LucentDreams]

How to fix, well show a top view of your lighting rig so I have an idea of howyou lightng, also try adjusting your phong a bit.

[ThirdEye]

What do u mean with "also try adjusting your phong a bit"? :shrug: Anyway i used two area lights casting 1500x1500 soft shadows + a hdri-like sky object

[LucentDreams]

sorry by phong I meant the smoothing tag, just set it to a higher degree should help a bit, this is a common problem with two and 3 point lighting. Another option is to adjust the overall scale of you object, and adjust the sampling on the soft shadows.

[ThirdEye]

Thank you for fast reply Kai :)

[LucentDreams]

just hope it works

Using a little chanlum might help reduce the noticeability of the artifacts some.

[audity]

It doesn't look like a shadow problem, it must be a surface illumination problem...

To remove this hard transition, you could adjust either the material's diffuse falloff or the light contrast. Negative values produce softer transition.

:bounce: Hope it'll work !

A combo of negative diffuse falloff and chanlum removed the problem, thank you guys! :thumbsup:

[malc0lm]

Just wanted to say that that is an helluva modell, keep up the good wrk!

[ThirdEye]

Thank you very much malcOlm, I'm trying to arrive to Renè Morel realism level using Cinema 4D even if this is my first head, I've spent a couple months on it so far :wavey:

[Janine]

I use a contrast value of -30 for almost all my light sources - makes the lighting much softer and gets rid of that problem.

Great head model btw!

Janine

[ThirdEye]

Thank you very much Janine, what about your settings for camera? I found useful a 120 focal lenght for heads... :shrug:

[AdamT]

120mm is a good length for a portrait shot. The longer the lens setting the less perspective distortion you'll get. That's why some high-end fashion photographers use really huge zooms.

Head's looking excellent! Very good job on the texturing.

[ThirdEye]

Thank you very much Adam, I found 120-130 is a good measure for portraits, i have to study a lot photographic tecniques for lighting too ;)

[ThirdEye]

Anyway the model that made me think "why can't I make anything so perfect?? By the way I want to try..." is this:

[LucentDreams]

On the note about camera lens lengths, for those who decide to use a profile and front view photograph to model a head it is also recommended you use photo's shot with a longer lens so that your reference image is more accurate, standard cameras anologue or digital by themselves will produce distortion.

Nice head and texturing, looks nicer with chanlum for as well, could you show an render of the mesh and of the model with one light (you can keep them small just curious to study)

[ThirdEye]

here's the mesh (i know there are some problems in the mouth region but i'll change the topology for my next head, i don't have to animate it) and the shading with 2 Hypernurbs iterations.

[LucentDreams]

for a first head that is one of the best attempts I have seen,fairly clean meash some weird areas as you said mainly around the mouth,try to keep those edge loops going all the way, but otherwise awesome job lot of good work coming out recently.

[ThirdEye]

Thank you very much kai, i want it to rock so i'm trying to keep patient and go on until the end ;)

[captain3d]

One of the best skin textures I have seen anywhere. The Eyes are still giving it away as a CG guy. Do these eys have an dactual lense and transparency etc or are they just an image?

Great work. Phil

[ThirdEye]

Phil Mc Nally tells me that my own texture (my first one) is one of the best he has seen anywhere? :surprised I can't believe it...
The eyes are fully modeled with lens and so on, probably a better illumination can give 'em justice. Thank you very much Phil, I'm really glad :)

[captain3d]

ha what do I know. I ve only made rubber people :-)

It just shows you how tricky the eyes really are. What makes that person alive?

Keep going...phil

[ThirdEye]

Only rubber people my dear ILM guy? ;)

[Beechdbum]

it is really a great texture, because of all the imperfections like scars ect. thats why it looks so much more human than one with no imperfections or a symetrical face

[Per-Anders]

it's looking really great thirdeye! you've been really persistent with this and kept improving it till you're getting exactly what you wanted, which is great :thumbsup:

btw it's good to see you here captain :)

thirdeye, are you planning to make a full body to go with this? it'll be interesting to see where you take it (though you may want a break after having worked on the same model for so long).

maybe you should post a tute on the making of your skin texture (it seems to be one of the most asked for things going, but there aren't many good tutorials on teh web delaing with this i've found).

[ThirdEye]

Thank you very much mdme, i don't think I'll add the full body, not now, i'm tired of this head, i want to finish it soon. I have to say this experience has been probably the most instructive 3D experience so far for me. I started using 3D in a studio drawing and rendering buildings (I am an architecture student) and then I really enjoied 3D but I've never had any kind of experience with organic modeling. I learned a lot about poly box modeling, edgeloops and this kind of stuff with this head... I learned how to make good textures even if these textures are really destroying my computer (3 *.psd maps, 70 megs each), but it has been quite funny too. I learned a lot about human anatomy, i kept watching italian famous ancient statues like Michelangelo's and Bernini's. I see these statues nearly everyday in my life here in Rome, but only now I can really appreciate their beauty. I have to say my next 3D work will be another head for a couple reasons. 1) I really enjoied this kind of things, i've been astonished by Renè Morel, Julian_J, Stuzzi, Ulf Lundgren and Robert Kuczera works, many people said me that i'm not so far from their realism level and I'm really happy, I'm winning the challenge against myself ;) 2) I really want to improve my head modeling skills, I think I'll start a full body only when I'll be really satisfied with my head modeling skills. Then will come the rigging step... ;)

[ThirdEye]

Oh for the tutorial... I've simply followed these indications http://www.lost.com.tj/Ulf/artwork/3d/behind.html and exploited the power of C4D gi and chanlum. ;) The rest is simple photoshop painting. :)

[Beechdbum]

well 3rd eye, you are doing a great job, make sure to keep posting, and if you have any more tips make sure to post those too:applause:

[Per-Anders]

excellent work... i guess living in Rome surrounded by all that beautiful sculpture... it was only a matter of time before you made your own great head model :)

i love the solidity of form that those artists had... i mean, you can take just one element form the whole object and it's good as a sculpture in itself, it's just incredible. you could literally just take David's nose and it's such a satisfying shape, the ammount to learn from these sculptures, you're so lucky to be where you are. (not to mention being able to get real tartuffo on the square (not that nasty one with the tutti fruiti ice cream... but the chocolate lovers paradise one *drool*)

[ThirdEye]

Not only tartufo but also real pizza, spaghetti, lasagne, fettuccine... :D

About sculture... this is really a great website, look at it ;)

[Per-Anders]

thanks :) that's gone straight into my bookmarks... hehe you're making me hungry with all this food talk (italy has the best food in europe imo...) so time for me to make my own pasta, drizzled in olive oil, a little salt, some herbs and a nice tomato sauce... (the simple things are so often the best) right off to cook!

[ThirdEye]

Not to make you even hungrier but tomorrow I'll move to Apulia (south Italy) for holidays, I have many relatives there... Well In Apulia they have the hugest fields of corn (for pasta), of olives (for oil) and tomatos (for sauce) in Italy. :drool: My granny's really good at cooking, if you come to Italy let me know... ;)

[ThirdEye]

mmm Pasta and C4D... :lightbulb :D

[Beechdbum]

God i want real pizza, im sick of frozen pizza

[Per-Anders]

maybe we ought to have a favourite cg food thread (and you have to post your recipes).

[Beechdbum]

good idea:beer: :beer:

Maybe I can do a couple tutorials :D

[ray1983]

I really think that it is magnificent dude!

[ThirdEye]

last update ;)

[DaliFan]

that is one hell of a job ThirdEye

impressive man

[ThirdEye]

Hey, thank you dalifan :)

[Per-Anders]

that's great work thirdeye... but you have some shadow artifacts still on it (the diagonal lines accross the forehead) at least it looks like shadow artifacts from the bias being too small possibly? (or is it simply the compression?).. anyhow great work, amazing for a first ever head :) now you should go and have some of that great italian food to celebrate!

[LucentDreams]

he Awesome render I've learned quite a bit from your adventures in doing this head, I'm using the contrast option on my lights a bit more (not that I've been doing a lot of lighting in the last few days but a bit and I can see the difference)

What I would like to see is a image showing all the channels and the final composite

[ThirdEye]

Compression artifacts... on the tif they're not visible... it's a pity we're allowed to post only 40 kb max pics... and i don't have any webspace at the moment, i have to find a remedy ;)

And yes, here is 12.52 am, it's time to think about lunch... I think I'll have some spaghetti with tomato, tuna and chilli :beer:

[ThirdEye]

Be patient kai, when i'll finish this loooong adventure I'll post everything you asked me ;)

[Per-Anders]

well congrats it's a grea job, and have a good lunch... i'm off to bed as it's 4am (and so should you kai it's 5am for you! at least i have the excuse of having my wife force me to go and see lotrttt for the second time!

[LucentDreams]

Hey thats no fair spying on me Sadie, I'll have you know I fell slept for 5 hours and just woke up at five or so. ;)

[kiwi]

I take my hat off to ya thats brilliant work Third eye :thumbsup: :thumbsup:



If you can nail the lighting/contrast,and get the eyes looking more realistic its one that will definitely put you and C4D on the map so to speak :)



Stu.

[AdamT]

Looking better and better--and really great! I think the lips are maybe just a little too pale, though. A little more color?

[ThirdEye]

Thank you for your kind reply, i slightly changed many things in the mesh and in the texture, here's a postwork, for the "normal" image look at: http://www.cgtalk.com/showthread.php?s=&postid=322578#post322578 :wavey:

[pit]

Yehaw - Frontpage!!!! Congrats ThirdEye - it´s well deserved! You are doing a brilliant job on this model - keep it up! :buttrock:

[ThirdEye]

kiwi: already used ;) hdri-like skydome + 2 area lights
pit: hey thank you very much :wavey:

Ooops ok,I thought it looked really good..........Hes begging to be put in a scene of some description :)

[ThirdEye]

I will add a blurred background image really soon, time to make some photos around Rome with the digital camera of a friend of mine :love:

[LucentDreams]

must be nice when your simply living there, make some really nice highres ones and send them to us poor people who have nothing amazing in our city other than the world's largest mall with the worlds 4th largest dragon, a lifsize reproduction of the santa maria and the largest indoor amusment park, I wonder if the waterpark is the world's largest, must not be as they don't advertis that fact like everyone else in the damn West Edmonton Mall

[Twyst]

HAHAHA. That's SO true, Kai. I swear, we must live in the most over-hyped city.. that has CRAP for good scenery. Maybe I'll sneak on down to the Muttart sometime when everything's in bloom, and learn how to use my digital camera properly. :D

Oh, and don't forget, WEM is the home of the Albertan Submarine Fleet. Our waters are safe from enemy submarines!

ThirdEye: Fantastic work, by the way. The stuff I see on these boards makes me green with envy. must.. learn.. how..

[ThirdEye]

I've finally finished!! :bounce: :scream: :p :wip: :wavey: :cool: :D
