skin shader

arshlevon

been working on this skin shader for a little while.. i am taking a bit of a differnt approach.. most people i see using the max 7 skin shader use it like a standard shader and put the colors they want the face to be in the overall diffuse slot.. i did this at first and the results were okay but there were certain things i didnt like about it because the certain things change at difffent angles on the face like the darkness of the pores.. they are not always black, light gets in there and bounces around making them unnoticable from certain angles.. so i decided to control the color with the subdermal layers using maps.. so the top layer i painted to look more like zombie so the red layers beneth would bleed through causing the red tones.. i have only painted the top layer and am only simulating the other layer with colors.. it is still very much a work in progress as i plan to do more work on the top layer and actually paint the other layers and not just use flat colors.. here is a shot of the head so far and a flat of the epidermal(top) layer..

That's a pretty interesting idea there. Looks pretty good too. I haven't had to bother with any skin shaders, as most of my stuff is realtime, but I've been interested in some of the processes that are being used , lately.

you should start putting skin shaders on all your world stuff.. roman skin covered vending machines...mmmmmmm.. here is a closer shot....

i think this is kisk ass , i just wish i could understand it

good job!

Very cool Arshlevon. Keep posting your progress!

kleinluka

Very awesome so far...

MoP

Very cool. Maybe a little waxy and grey at the moment, throw a little more saturation in! Just a little! Definitely needs more colour variation on the diffuse texture too, around the eyes especially.
Looks very nice though.

Man, that is cool: I can just imagine what he's gonna look like with, I dunno, veins 'and stuff'? painted onto the sublayers. Very cool technique! The closeup even looks like he's got a shallow bumpmap on him!

That really is quite something, the skin looks very realistic...actually it's an ingenius method that you put into practice...just one comment and that's the skin looks just a tad shiney, that makes it look a little plastic, I reckon if you tone it down.....just a little you'll be on to a winner....btw...this is in 3dsMax 7!!....cool...

arshlevon

i think the reason it comes across as too shinney is because there is no spec map yet.. just an overall spec value.. i think once i paint a spec map the spec will be in the right places... thanks guys.. when i am done i will make it available for everyone..

edit: oh yeah and the shader is a mental ray shader.. so users of maya can also use it.. i will just have to export an mi file or just post the vaules of the map slots..

Awesome work. Appreciated all the more since I'm trying to get a solution running for Maya/MentalRay using Tom Bardwell's skin shader as a base.

okay a little update.. been working on the next skin layer.. the subdermal layer..
@Mop...here is where more of my color is comming in... so if i want more color in the shader this is the level to do in.. also added a bit of a temp spec.. not finished, didnt really spend too much time on it.. just to kind of push it a bit more .. i am running out of rez on the map so i might double size it and start to rework the bump... you can really tell on the lips , its not as crisp as i would like it to be.. thanks for the crits..keep em comming..

arshlevon

oh yeah almost forgot.. here is the flat of the subdermal layer... looks like he got ahold of some tan in a bottle

here are just some quick lighting tests using some hdr images..

looking good... he feels abit splochy... lots of lighter areas dabbled over his skin... His lips need some color and i think you need to vary the colors of your subdermal map more... get more saturation in it... and if your going to be rendering that close then id suggest using a higher rez map. check out my maps and model here to get an idea how i used the shader
