The Shading Material functions provide for specialized shading operations, such as fuzzy shading and adjusting the shape of a specular highlight.
FuzzyShading
This function emulates a surface similar to velvet or moss, and is similar to a Fresnel calculation. Incidentally, it is also useful for shader effects such as a scanning electron microscope.
| Inputs | Description |
|---|---|
| Diffuse (Vector3) | Takes in a texture to be used as the diffuse color. |
| Normal (Vector3) | Takes in a normal map used to perturb the surface of the fuzzy result. |
| CoreDarkness (Scalar) | Value used to darken the object wherever its normals become parallel to the camera, generally toward the center. The higher the number, the darker the core. Default is 0.8. |
| Power (Scalar) | Controls the rate of falloff from the core to the edge. Default is 6.0. |
| EdgeBrightness (Scalar) | Controls how bright the surface becomes as its normals become perpendicular to the camera, generally toward the edges. |
FuzzyShadingGrass
This function is designed to provide the diffuse portion of grass shading. Similar to FuzzyShading, this function allows you to blend in a new color at the edges by first desaturating by a given percentage and then applying a custom color to the desaturated area.
| Inputs | Description |
|---|---|
| EdgeDesat (Scalar) | 0-1 number controlling how much the edges of the object should be desaturated to make way for the edge color. |
| EdgeColor (Vector3) | This color will be applied to the edge area. Use EdgeDesat to desaturate that area if too much color mixing is taking place. |
| Diffuse (Vector3) | Takes in a texture to be used as the diffuse color. |
| Normal (Vector3) | Takes in a normal map used to perturb the surface of the fuzzy result. |
| CoreDarkness (Scalar) | Value used to darken the object wherever its normals become parallel to the camera, generally toward the center. The higher the number, the darker the core. Default is 0.8. |
| Power (Scalar) | Controls the rate of falloff from the core to the edge. Default is 6.0. |
| EdgeBrightness (Scalar) | Controls how bright the surface becomes as its normals become perpendicular to the camera, generally toward the edges. |
