Material (Surface) Shaders

Material (Surface) Shaders

This directory contains the basic and more complex tools used to define a shaded object’s surface. Besides the usual Blinn, Phong, and Lambert shadings, you’ll find several more specialized tools, such as subsurface scattering, ambient occlusion, and toon shading effects.

Preset name	Output	Description
Anisotropic	Color	Creates a Ward-type surface illumination with two adjustable speculars.
Blinn	Color	Applies a Blinn surface to an object.
Constant	Color	Applies a Constant surface to an object.
Cooktorrance	Color	Applies a Cook-Torrance surface to an object.
Flat_light	Color	Applies a flat-light surface to an object (viewing angle not considered).
Lambert	Color	Applies a Lambert surface to an object.
Lume_Metal	Color	Defines a metallic object’s reflective properties in a realistic way.
Phong	Color	Applies a Phong surface to an object.
Shadow	Color	Extracts a shadow projected onto an object for pass purposes.
Sprite	Color	Applies a color (or image) and a matte to an object to create a sprite or billboard. Allows infinite transparency.
Strauss	Color	Applies a Strauss surface to an object.
SSS_Fast_Simple	Material	Material Phenomenon that defines and applies a simulated subsurface scattering effect on the shaded object.
SSS_Fast_Skin	Material	Material Phenomenon that defines and applies a skin effect on the shaded object. This is essentially a more complex variant of SSS_Fast_Simple that support additional levels of specularity, light scattering, and reflection.
Toon_Host	Color	Controls per-object contour rendering.
Toon_Paint	Color	Controls toon surface shading attributes or “painting”.
Toon_Paint_ Ambient	Color	Controls the base color and ambient attributes of toon surface shading.
Toon_Paint_and_ Host	Color	Combines the Toon Host and Toon Paint shaders.
Toon_Paint_ Highlight	Color	Controls the base color and highlight attributes of toon surface shading.
Toon_Paint_ Rimlight	Color	Controls the base color and rimlight attributes of toon surface shading.
Toon_Paint_ Rounded	Color	Controls toon surface shading attributes using a different highlight style.
XSIAmbientOcclusion	Color	Samples the scene from points on an object’s surface and returns one color for areas occluded by other geometry and one color for unoccluded areas. Partially occluded areas receive a blend of these two colors.

Illumination Shaders

This directory contains simplified, illumination-only versions of the most common shading models, as well as a few more specialized tools.

Preset name	Output	Description
Anisotropic_shading	Color	Creates a Ward surface illumination with two adjustable light directions.
Anisotropic_uv_ shading	Color	Creates a Ward surface illumination in the U and V directions.
Blinn_shading	Color	Creates a Blinn illumination texture on an object.
Cooktorrance_ shading	Color	Creates a Cook-Torrance surface illumination on an object.
Flat_light_shading	Color	Creates a moviescreen-like illumination texture on an object.
Lambert_shading	Color	Creates a Lambert illumination texture on an object.
Phong_shading	Multiple Colors	Creates a Phong illumination on an object.
Simple_Shadow	Color	Creates an editable shadow from any object it is applied to. Useful for creating a shadow pass.
Strauss_shading	Color	Creates a Strauss illumination on an object.
Translucent_shading	Color	Applies a editable translucency onto an object.

Raytracing Shaders

These shaders create specific raytracing effects.

Preset name	Output	Description
Dielectric	Color	Returns the “reflection intensity” or “refraction intensity” of a surface.
Refraction_diffuse	Color	Applies a diffused refraction to an object or shader.

SOFTIMAGE|3D Legacy Shaders

SOFTIMAGE|XSI provides support for all SOFTIMAGE|3D shaders. Supported here are a wide range of the most popular SOFTIMAGE|3D shaders.

Preset name	Output	Description
Dusty	Color	Simulates the dirt and dust that accumulates on surfaces.
Easy_Atmosphere	Color	Allows you to quickly create planet atmospheres.
Env_atmosphere	Color	Simulates realistic planet atmospheres.
Env_ball	Color	Reproduces environments by “photo-capturing” whole environments.
Env_cubic	Color	Creates a cubic environment. You assign six images to the up, down, right, left, front, and back of the cube.
Env_horizon_day	Color	Creates a day-like horizon environment with a sun, clouds, and the ground.
Env_horizon_ map	Color	Creates a day-like horizon environment with clouds, and the ground.
Env_horizon_ night	Color	Creates a night-like horizon environment with stars, a moon, and the ground.
Env_sphere	Color	Takes a single image file and maps it to the environment using a spherical mapping.
Fire	Color	Simulates a surface-projection fire effect. This is not volumic.
Velvet	Color	Creates a satin or velvet-like effect on a surface.

Subsurface

This directory contains several preset variations of the same physically-accurate subsurface scattering shader.

Preset name	Output	Description
Jade	Color	Uses the physically accurate subsurface scattering shader to create a photorealistic jade material on an object’s surface.
Skim_Milk	Color	Uses the physically accurate subsurface scattering shader to create a photorealistic skim-milk material on an object’s surface.
