Skin shader mk2 - preview pimp

J.I. Styles · Apr 2006

quick preview pimp of another real time skin shader I'm hacking away on. Ripped out all the things I liked from my last one and applying all the new ideas I've either come up with or blatantly ripped off from other people

new features are a micro detail overlay map, new soft light blending algorithm, and independant colour inputs for hemaglobin and melanin layers hack.

no download yet as I need to test a few more things and try other things out before finalising a public release.

do you know that term ... how's it go again ..
wait, wait, it's on the tip of my tongue ...
ehm ... oh right ...

SWEETNESS !!

Renaud Galand · Apr 2006

nice one dude

I can't wait to play with this one

pior · Apr 2006

Some hot layers in there.

retleks · Apr 2006

Man, that's great. You say it's real time? Any chance it can be used in xsi?

ThE_BirD · Apr 2006

looks great..can't wait to give it a shot

Eric Chadwick · Apr 2006

Looks great!

To combine the high-freq map with the other normalmap, are you using an overlay op, or is it just multiply or add?

aesir · Apr 2006

gimmee?

arshlevon · Apr 2006

awesome awesome awesome... now just make it self shadowing and you win at everything in life.

doc rob · Apr 2006

hooray! I look forward to trying it out.

Rekmar · Apr 2006

looking really awesome man, I'm looking forward to its release

btw, how is the license for it? can I implement it in my game?

vahl · Apr 2006

HAWT !!! il already loved your previous one, can't wait to get my hands on that one

J.I. Styles · Apr 2006

Equinoxx, Renaud, pior, ThE_BirD, doc_rob and vahl: big thanks guys, good to see people like the look of it! Try and get it in your hands sooner rather than later

retleks: thankya! Made a half-arsed attempt to answer the xsi question over at cgtalk, basically it -may- work straight out of the box, but it also may need translation from max specific inputs to whatever xsi puts out (property names for things).

EricChadwick: cheers Eric! Still a little playing around, but using an overlay blend op - thinking it'll be simplified to:

+ (tex2D(MicroSampler,TexUV*MicroScale).xyz * 2.0 - 1.0)

Pretty much mimics a photoshop overlay method by having the normal maps blue channel at 50% in the image. wondering if I need to re-normalise after the op, or if there's negligable difference.

aesir: sooooon(ish)!

arshlevon: ooh how I want viewport shadowing -- I'd want to do full scene viewport shadowing though so -maybe- possible to write a scene shader. Pretty much every attempt I've seen at shadows besides ofusion has failed in max viewport, so I don't hold much hope though. Maybe I should just do another technique which has a shadow map input so you can at least pre-render a shadow map and stick it in the slot

Rekmar: cheers for the praise - licensing, to be honest I hadn't even considered anything besides "use it however you want, just tell me and show me how it's being used since I love to see where stuff ends up." I think that's my license agreement

name credit is nice too. And sexual favours.

Eric Chadwick · Apr 2006

You might notice the specular getting weird, if not then you're probably in the clear.

Thanks for sharing your shaders.

Slum · Apr 2006

Oooh, sexiful. That looks great. You are awesome.

Ben Cloward · Apr 2006

That's looking great, Joel! Keep it up. Can't wait to get my hands on this one.

Shaders are fun. I wish that more artists were learning to write them.

Joshua Stubbles · Apr 2006

I think they would, if they got paid more to do it :P
Many artists are already overworked. Hard to find time/energy to learn a new language.

J.I. Styles · May 2006

ok, released baybeeee

grab it off my site under the hlsl area
http://www.jistyles.com

Just a note too, the micro detail map is a tileable normal map, but with the blue channel taken to 50% so the overlay works. Just the same as doing a photoshop layer overlay for a normal map.

I'll probably get another update soonish with source files for a head or something, just for example settings.

vahl · May 2006

w00t !!!

edit : your shader doesn't seem to support mirrored uvs unfortunately

I had to separate the mirrored part, mirror the uvs horizontally and apply mirrored maps to get a decent result.
(just flipping the green and/or red channel didn't work

the part that was working had a nice render though, nice work man, very easy to use.

Weiser_Cain · May 2006

I technically qualify as an artist, how would one learn to write shaders?

EarthQuake · May 2006

Tested it out, get all kinds of shading errors.... included a max render to show what it should look like

max 8 btw

EarthQuake · May 2006

aha fliped green channel was the prob. yay PRETTY. jsut have to tweak maps now. Maybe an option in the shader to flip green like ben's shader?

[edit] yay for bald girls

[edit][edit] tweaked spec a lil...

J.I. Styles · May 2006

Vahl: are you using max 6, 7, or 8? Unfortunately max has had some bad issues in all versions with the data it spits out for viewport rendering -- max8 seems to be ok with most issues (including mirroring uv's) but still has a few problems.

Weiser: just start pulling apart the .fx files that come with max and reading tutorials online; once you've got a handle on that and graduate to print books you should have a fairly strong understanding.

EQ: haha sorry, should've mentioned that - I should change it to max standard Y direction

the default settings are pretty ugly with the default maps since they're values I'd based off a model with its own maps, so my bad -- once you've got it nice and balanced, post your pretiness! I'm definitely looking forward to seeing what people do with it

Joao Sapiro · May 2006

i want

now ill have to get a pixel shader graphic card ahaha ! hm...does it work with a gforce mx 4 ?

vahl · May 2006

JI styles : i used max 7...
although after that *tweak* I had to do, the rendering is really cool, very close to what I expected from such a shader, once again, great job man.
and yah, the default settings are a little too strong but after a few quick tweaks, they are really cool, I love the fresnel thing

kuman · May 2006

hey ji styles
an artist i work with, eric chadwick, sent me a link to your shader you made. great stuff, thanks for sharing it. i did a screen caps of some of my work using your shader.

Rekmar · May 2006

/runs to try it

if I end up using it in my game, I'll let you know and probably will give credit too

about sexual favors.. eeeeehh

Nafets · May 2006

The results look fantastic, but ive got a problem:

The object is rendering completely transparent, and im getting the error

error: Material "Skin ( DirectX 9 Shader )" not supported by the translator. Will render black.

Anybody know what thats about???

Scott Ruggels · May 2006

Nice, Wisah I could use it in Maya. All I have max wise is Max 6

obson · May 2006

Nafets: Direct x 9 shaders won't render, it's a viewport only thing. Use printscreen or some other screen grab method to get shots of it.
