Human Skin WIPs and Tips (Everyone feel free to post your own skin WIPS here too)


#1021

it looks fairly good… town down the specular… give it some blue/purple tint to it, and some more red tints in the difuse of the skin, that will give you a better result i think

i like the natural skin look now… so dont make the overall look to red. most people make there skin , like it has been in the sun very long.

what materials/renderer did you use?

brazil wax?


#1022

Well. thanx ivo. ur quite right with the specular. and turn down scattering a bit to. The Renderer is Mental Ray.


#1023

cant get mental ray figured out right , yet… cant get good skin with it… ill probably go with brazil.

But i still have to do some things with my model before i make some skin tests.
if ur interested you can look here… im going to try to make very realistic skin, when i get to it… hope it works out right

At last I’m getting to grips with Lightwave’s G2 sss.

Hi dudes i have seen here very good shaders, with no doubt a reference place :slight_smile:

This is just my try, and if you want to see wires or the render tree yo can go there:

nice shader… how did you do the eyes… photo… or painted… with reflection map in reflection slot… ?


#1027

hi Ivo D and thanks for your comment, well all the maps are painted in photoshop but there are no reflection mapped in the reflection slot, the eye just reflects an hdri environment.


#1028

also tryed that… but than you have to change the hdri settings am i right, so you only get the big highlights? havent found a good hdri yet… caus most reflect al over the eye when i do that, and in reality that isnt the case.

dont know how to get that yet


#1029

Hey Ivo D, you can try to do it with composition, i do it that way, you render in one layer your model without reflection and then you render only reflection with the hdri settings that you want, you can change the exposition or gamma at your taste and then you just do an overlay in photoshop with the diffuse and the reflection layer , hope this helped you.

Cheers.


#1030

true but i want the accurate material effect, when animating for instance.
i dont like compositing that much, cause a 3d model is something that makes you able to move and view the model from all angles. well i always want to make my stuff with animation in mind, so everything works always… ill look into it soon still busy, but when i tryed i couldnt get the result in the time i had

@Combat Mantra:
big congrats, man!
This is definitly one of the most covincing skin shaders i’ve seen so far. I’m new to MR and i was asking my self how to do the glossy reflections on the skin.

@ Ivo:
dunno wether you know this already or helps u at all but i thought about this eye reflection thing. And in max it is very easy to control reflection amount. I just copied the hdri i use for lighting put it into the environment channel of the eyes’ material and turned down output. voila, u have nice highlights, which also work in animation. additionally, u can put a fresnel fallof in the reflection slot, i think.

btw u can get some lightprobes on http://www.debevec.org/.


#1032

Hello Roberto, thanks a lot for your comments:) , well i am usin xsi and in the reflection there are two slots here i put you an image
btw you can control the glossy reflections with a texture map.

Ciao.


#1033

I love that skin, combat_mantra :thumbsup:

For the lighting, did you use only HDRI? Or some lights placed into your scene as well? I really like the soft ambient lighting that you’ve got.


#1034

Hi Leigh, thank you very much, glad you liked it :slight_smile:

About my setup: the scene is lighted with fg with a jpg environment making the fill light, the key light is an area spot that is connected to diffusion shader, and as back/side light another area spot, for reflections i used hdri, hope this helps.

Ciao.

im trying to make a realistic skin shader now im doubting a little where to start of from.

i use 3ds max.

should i go fro ma standard max material, max skin shading material, brazil skin shader?

and with th reflectivity of the skin, do you also make a refletion map… for where it reflects? or is it best, to only put it in the highlights.

highlights arent created by specular, at all ? just reflections… ?

i know reflection is the obvious way to create highlights, but specular is needed for the moistere on the skin, and you need o make an intensity map for that right…

just want to grasp some more info , on things im doubting about, i know there are a lot of ways, but im searching for the most realistic aprouch, dont want to fake things, want to let my skin shading look realistic in every situation.


#1036

Anyone know where i can find a block of translucent silicon? Its gunna be a base for my shader.

eek


#1037

come on guys, shoot me some good advice! i need a more realistic aspect :scream:


#1038

Thanks for the info :slight_smile: I’m still coming to grips with XSI’s lighting toolset, so the info is appreciated!

ivo D - the problem with using specularity is that it tends to look plastic. Whereas using low levels of tinted reflections tends to look more realistic, and it also helps to give skin some moisture. The trick is creating an appropriate reflection map - study your own facial skin and you’ll see how some areas are much more reflective than others (for example, the skin directly beneath our eyes is more reflective than the cheeks) and paint accordingly. As for shaders, I’ve seen some nice results from Brazil, but can’t offer much advice in that regard since I’ve never used it myself.

murnau, in all honesty, your model itself needs more work if you want it to be photorealistic…


#1039

I’ve been tweaking my shader some more, but I find it hard to judge if I’m going in the right direction, I used some sss, now, I was wondering what version is the best according to you guys. CnC requested.

In the last render I changed the color of his eyes, I had them changed to brown because it looks like he’s a zombie with blue eyes… I’m trying though

I don't like the HDRI lighting that much, it feels like it's simply taking out any shading...

SSS, FG, HDRI, but a little more color in the skintexture.


#1040

ok, so… one friend help me as a host so i can finaly post something in the forum…
this is the skin texture, in which im working… i used some color, bump, tranlucence, diffuse, specular, and reflective maps… and this s what i got, i also used one pretty good shader that i find in a cg page, but if somebody nows about another good shader, you can tel me, im using maya5.0
well. let me know what you think about it, so i can do it better
