Next Generation surface shader for ((DAZStudio)) providing HDRI reflection support, Subsurface Scatterings, translucency and more.

== Product Description==

See the [http://www.daz3d.com/i.x/shop/itemdetails/-/?item=7412 DAZ Product Page] or [http://artzone.daz3d.com/wiki/doku.php/azproduct/7412 Artzone Wiki] for a full product description.

=== Tiling===

HumanSurface supports tiling textures via the __Tiling__ parameters. If tiling is set to ''3'', the texture will be repeated or tiled 3 times.

=== Specular===

[[HumanSurface_ui_specular.jpg]]

==== Glossiness====

The specular model of HumanSurface is greatly improved over the Studio default shader. The shader uses a proprietary BRDF that pays special attention to glancing lights; preserving the specular shape and avoiding ugly clipping and harsh falloff.

==== Sharpness====

The following images were rendered with specular only; Glossiness of 4%.

=== Reflection===

HumanSurface allow for HDR/Environment mapped reflection maps (in latitude/longitude format) as well as ray traced reflections. Both Modes of reflection can be blurred to achieve oily skin effects.

{img src="img/myicons/alert.png"} More info on creating HDR can be found in the __Creating Environment Maps__ section on the UberEnvironment page.

==== Fresnel====

[http://en.wikipedia.org/wiki/Fresnel_equations Fresnel's law] basically states reflection at glancing angles is stronger than direct. The provided Fresnel controls give us explicit control over this effect.

=== Velvet===

The velvet component is designed to simulate the effect of tiny hairs on the surface. This helps to provide the look of ''"Peach Fuzz"'' on a face but can also be used to make a surface look like fabric like in the HumanSurfaceExpansionPack1.

=== Subsurface Scattering===

Subsurface Scattering can be used to simulate the scattering of light through transluscent surfaces like skin.

All images were rendered with a gray diffuse and red Subsurface Color.

{img src="img/myicons/alert.png"} Subsurface Scattering is based on Diffuse; Diffuse must be active in order for Subsurface Scattering to work.

[[HumanSurface_ui_sss.jpg]]

==== Refraction====

Subsurface refraction represents the refraction or how much light is bent as it enters the simulated surface.

[[Image:HumanSurface_sss_strength100_kfr5.jpg]]||

==== Scale====

The Scale of the objects; this effects how far the light scatters through the object.

|| Scale 2 | Scale 4 | Scale 6 | Scale 10

=== Displacement===

The displacement controls are the same as the default shaders with one import addition: the abiblity to properly ray trace displacements.

((3Delight)) allows ray tracing ''before'' or ''after'' displacing geometry. Since displacing the geometry generates micropolygons and a more dense mesh, displacing ''after'' will negatively impact render times but give you better visual results and can get rid of black splotchiness in rendes.

In order to ray trace ''after'' displacement, turn __Trace Displacements__ on.

== Tips and Tricks==

* Use the 'Active' toggles to isolate the contribution of individual components. For example turn off the Basic Specular, Reflection, Diffuse, etc, when dialing in the size and sharpness of the Secondary Specular. This helps to make it more clear what the controls are doing. When you turn everything else back on, you then only need to worry about dialing in the ''Strength'' of the Secondary Specular.
* Often Better results can be achieved by using Reflection ''in stead'' of Specular. The reality of it is Specular is simply a gross approximation of Reflection. Try using blurred reflection and apply the specular map and a Reflection Strength map (Ideally using HDRI like the ones provided).
