mia x + misss fast

Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Hello,

i am trying to add some 'skin element' to my mia material with misss fast shader. But after i plugged the fast shader into the additonal color of mia, it crashed when i hit render..

Some kind of bug? how do i fix that?

I am getting alittle lost with these stuffs, it's mia material and misss_fast_shader. I am just trying to get some skin translucence look with the fast shader.

i followed the tut from cgbootcamp. Sub-Surface Scatter 03: Adding SSS to Any Shader on Vimeo

The mia shader allows for accurate BRDF. You need to plug the sss shader into the additional color slot of the mia shader. Just keep in mind the whole idea of scale and how the scatter is tied to it. The reason the color is "blown out" is because the mia shader needs to have its diffuse set to 0 otherwise it is doubling. The sss also works much better in a linear setting. Hope that helps....
