DX9 Skin Shader Using UDK

[TheMetaMorphe]

Hi,

I'm currently working on a Real-Time Skin Shader using the material editor of UDK.
I'll post my progress in this thread.
C&C are welcome !













The only post effect I've applied is : Bokeh DOD ( EPIC ), Chromatic Aberration and Filmic Tonemmaping ( EPIC ).

For my test I've use a head that I've made for "Kylotoon Games" ( except normal and mesh ).

You can send me a MP if you want me to use your models for my test !

looks quite good so far!
my only questioning would be how it'd look in a more practical environment, mainly outdoors at daytime with direct sunlight. I myself have a DX9 skin-like shader and I absolutely love how it looks in the editor's previews (animTree viewer, mesh viewer, etc) but once in outdoors it loses a lot of its specialness

I myself am using some CustomLighting that basically bleeds the light into a further angle than the usual lighting angle and colors that light-bleeding into darker red'ish tones, plus the regular material Transmission input. what's your approach at this?

[TheMetaMorphe]

Thanks for your reply !

Here some screen in outdoors env :

Default UDK Morning Lighting





Default UDK Midday Lighting





Default UDK Afternoon Lighting





Default UDK Night Lighting





I'm still using the Transmission input but combined with a greyscale light ramp ( with a dotNL in its input, same technique as TF2 or many other games but with a Greyscale Ramp instead of color ramp) who permit to me to control the sharpeness of the light on the mesh. I've got an other DotNL who gives me a light-bleeding ( still in progress ). I put this to my TransmissionMask and in the TransmissionColor input I can set my colors ( 2 for now, one the incident light and one for the inscattering light ).
Everything for now is not perfect plus I need better mesh with nice normal map and diffuse.

Sorry for my bad explanation :s

That looks really great, for using transmission, great job.

[TheMetaMorphe]

Thanks !

Transmission can be really good with some tricks.

I think this is the best skin I have seen so far in UDK. Very nice.

[Eduardas]

can you share that love, with community

Thank you but I think it needs more works to be good as I want.

can you share that love, with community

I think I will when the shader will be finished.

Can someone know a way to calculate dynamically the thickness of a mesh in udk using the mat editor ?

[TheMetaMorphe]

So some news,

I found a better mesh here : http://www.ir-ltd.net/infinite-3d-head-scan-released







I've change a lot of things to my technique but still using the Transmission. I think I'll move to custom shader soon since I'm a bit limited for now.

[TheMetaMorphe]

Ok so I've moved to custom lighting and I've have to admit that is very powerfull

Screeny :











C&C are apreciated !

[skwisdemon666]

That last batch looks like photos. Wow.

[TheAgent]

Very nice stuff, keep up the good work.

Thanks it's much appreciated !
