mia x + misss fast

Maya 2020 fundamentals - modelling the real world

Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

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....
