here we are nearly 4 years later and this shader still looks excellent.

wow, this is so cool, did u use sss shader? in game industry, do they use sss for their in-game model also?? I wonder how u made the normal map, is it from zbrush or baking from high res model?

Yup its a SSS Shader. Iin the games industry we often use SSS shaders in realtime games yes

oh wow, I thought SSS is heavy to render lol. So how about the maps? for SSS, we need subdermal, epidermal, backscatter, specular, and diffuse right? so u have 5 maps for 1 character? Sorry if I ask too much, I just wanted to try low poly later. lol thanks

SSS in game shaders is usually an approximation done in the shader itself, still some realtime shaders will make use of an epidermal map

oooh i see. Thanks for this info

Very interesting. Amazing results..
Im gettin ma nose further into the shader thing myself..
Which software did you use for this? ShaderFX?
Or you programmed it by hand?

this is pretty old, its the default SSS mental ray skin shader in max

Duh!
I thought it was realtime

my class just recently touched on uv maps (to which im absolutely horrid at
hopefully i actually get taught all this xD my teachers kinda...hopeless.

naw you dont need to learn this kinda stuff not just yet - just focus on the basics such as low poly modelling, high poly modelling, making good uv maps and making some nice textures.
Getting caught up in technology too fast will just blow your mind.

trust me, this gallery has already blown my mind. In class, we work with maya in nurbs D:apparently its easier for beginners?

Its great you have passion for this work so early seriously
Im about to setup a chatroom here: [link]
Feel free to join and ask me and/or others questions!

i have to many nub questions to ask infront of people

Also if your bad at uv mapping, try a program called uv layout. super easy to cut the model and it does un wrapping for you.. you should know the traditional way as well. but you can learn that with practice.

So, the elbow joint, is it done the same way the knuckles on the hands are done? With a sort of "V" shape?
👍: 0 ⏩: 1
Yeah, Its a good way of doing things i think

That is valuable lecture to read by eye.
May you explain what is the function of each layer or step, please?
👍: 0 ⏩: 1
Sure! I will Try
Flat - this is just a flat skin shader material applied to my low poly mesh.
Normal + Bump - this is the result after i have applied my normal map and bump map to the low poly mesh. Contains wrinkles and subtle muscle shapes.
Diffuse - this is the result after applying my diffuse map into the diffuse slot of the material, it contains colour information only.
Epidermal - this is the result after apply my epidermal map, it contains colour information of what the skin would look like without any blood.
Subdermal - this the result after applying my subdermal map, it contains colour information the deep blood layer of skin ( quite orange )
1st Layer Spec - this is the result after apply my specular mask to control the first pass of specular intensity.
2nd layer Spec - this is the result after applying my specular mask to the second pass of specular intensity. ( this reduces alot of the intensity of the fina specularity of any material - if i went back and removed the 1st pass specular from this image i would have a greasy looking arm again.
HDR Edge reflection - I apply a HDR map and restrict its reflections to only the edges where the HDR map deems light will reflect. Just helps to pop the arm out from the grey background and give a more natural look!
I hope that explains a little bit more ?

I appreciate your time on giving me this valuable lecture! I wish you all the best, and I am looking to see more 3D artworks from you.
The process you go through is kinda when an artist start to draw the bones then the skin, then sketches and then coloring different stages. It is nice to know your process! Thank you again!
👍: 0 ⏩: 1
Your very welcome man, THe process is truly about thinking every step of the way. I believe that skin shader is a bit old - i should be able to do a much better one now.
Maybe soon i will go back and update it again!

Here you go dude, see if that helps you out

oooh so YOURE the one who posted this on cgtalk along time ago
VERY impressive

Haha Yes! I found deviant art and decided this would be the best place to simply upload ALLLL of my work, from old to new

Diffuse + Bump in Alpha, Specular Colour with Value in Alpha, Normal. Total of 3 textures ? thats fairly standard for a character.
The shader performs a fair few different techniques and instructions - maybe thats whats confusing

i thought you had heaps of layers of specular like separate specular maps.

Nope Just 3 Maps
