I have a working hair shader now. It seems to work well. Here's a test render of some ZBrush Fibers. If anyone wants the hair material to test I will be adding it to the LiveDB under Materials>Misc and I will call it tonysculptorHair. If anyone does any good renders with it please post it or pm me.
Best

That looks great.
I will be starting something a sculpt soon and was thinking about hair. I'll have a look for sure. Did you get anywhere with an eye shader?
Also, is the worflow from ZB hair out to somethign that can be rendered in octane fairly straight forward?

Zbrush fibermesh can be easily exported out as polygons. You just find the subtool that is the fibermesh and export that. Simple.

Had you given any thought about making a zbrush to Octane video tutorial on rendering and shading a character. I would buy it if you did.

Really nice work! I love the skin and the sculpting to! I need to have a look at the sss material

What I lack is some sort of sss node to be used as a mix map. as it is now its hard to do detailes in the back scattered areas

Hi there tony, I used your sss and intergrated it into what i have for poser and the plugin.. i realy like it, I have one problem tho, I tend to get red fireflies in the darker areas.. the node structure is pretty complicated and Im wondering if there is a spesific value you recomend me adjusting to get rid of that.

... great work my friend, you really know your stuff.

I actually turn down the Hotpixel reduction value and just shoot a ton of rays at it. I'm glad it is working well for you.

I found the culprit to the firefly issue, under material one material mix material 2, medium [scattering] phase, scattering direction, must be set to 1.0 instead of 0.0, cant see the difference really but it eliminates the fireflies

@tonysculptor Thanks for the hair material, tried it here and it works great.
Having a bit of problem with the new skin material. I think I missed the input point for the textures as shown. Any help would be appreciated.

Tugs,
Maybe you might need a bump map or a normal map or higher resolution geometry?
