View Full Version : Tut available for SSS Fast Skin shader
lemiere 07-02-2005, 05:54 AM Recently completed a short tutorial about Mental Ray's Subsurface Scattering Fast Skin shader. I wrote it using 3ds max 7, but can also be useful for Maya users with proper lightmap linking.

Hope it's useful and had fun writing it.

I don't have v7, but all the same this has been a great help so far learning to set up subsurface effect, a lot of insight for me definitely.
Thankyou sir :thumbsup:

Thanks heaps lemiere!
I'm actually using a Renderman renderer, but your tutorial has been invaluable in showing me all the different layers needed to acheive the final look. I already have an idea of how to set these up in Renderman.

Hi Augh,
Glade it was some help. Checked out your Archangel project. Looking good. Can see you're up to the skin stage.
All the best
hiya, thank you soo much for providing the tute on SSS.:bounce:
It's a hard subject actually, because the result often varies, but I'm really grateful for this tutorial. A good max SSS settings is hard to come by.
I wanna ask a question tho, I found a part that is hmm............... hard to locate :
Scale Conversion
The SSS Fast Skin Shader is dependant on the scale of the model. It is best to use models that approximate real world sizes. The head model in this example is 190 mm wide, which, including the ears is the average width of the human face. Scale conversion can be used when the scale isn't quite right by adjusting the overall subsurface scattering effect. In 3ds max 7, Scale Conversion is found under the Advanced Options. Setting it to 100 divides each of the three Diffuse layer's radius: the Epidermal, Subdermal and Back surface layers. The result is a return to the harsher, darker shadows, and effectively disables the scattering.
I'm not that really advanced MAXER, but where's this advanced option located ? :scream:
Sorry if it's a lame question.... but I couldn't find it, and I wanna to try the scale conversation. Thanks a lot dude !:thumbsup:

Hi dees,
Like your signature pic! What's the cat shooting?
Yeah, sure, scale conversion is tucked away in the Material Editor - not a lame question.
In your Skin Material, scroll all the way down, right the way down and before hitting the very bottom, where the Shader maps are listed, you will see 'Advanced Options'. It's the last section before Shaders. Three parameters down in Advanced Options, after Scatter indirect illum. is 'Sacle conversion factor'.
Glad to hear the tutorial is working for you guys.
Greatwork!
How can i made it in maya?
