Overview


Falloff produces a texture with values from white to black, based on the angular falloff of the surface of the geometry based on the face normals. 

 

 

 

Parameters


 

 

 

Color A (Front) – Controls the front color. A texture map can be assigned to this channel. 

Color B (Side) – Controls the side color. A texture map can be assigned to this channel. 

Falloff Type – Specifies the method for determining falloff range:

Perpendicular/Parallel – Sets the falloff range based on a 180-degree change in face normal direction.
Towards/Away
 – The falloff range is based on a 180-degree change in face normal direction.
Fresnel – Sets the falloff range based on the IOR (Index of Refraction). The color range is controlled by the IOR.
Distance Blend – Sets the falloff range based on the distance that is specified from the camera.

Direction – Specifies the direction for defining falloff: 

View Z – Defines the falloff based on the camera viewing direction (camera Z-Axis).
View X – Defines the falloff based on the camera X-Axis.
View Y – Defines the falloff based on the camera Y-Axis.
Explicit – Defines the falloff based on a defined position.
Local X – Defines the falloff based on the local X-Axis.
Local Y – Defines the falloff based on the local Y-Axis.
Local Z – Defines the falloff based on the local Z-Axis.
World X – Defines the falloff based on the world X-Axis.
World Y – Defines the falloff based on the world Y-Axis.
World Z – Defines the falloff based on the world Z-Axis.

Invert – When enabled, inverts the color values.

 

Mode Specific Parameters


 

 

 

Direction (Vector) – Defines a specific direction when falloff Direction is set to Explicit.

Fresnel IOR – Defines the IOR (Index of Refraction) used by Falloff. This option is available when Falloff Type is set to Fresnel.

Far Distance (Color A) – Specifies the Far distance value. Available when Falloff Type is set to Distance Blend.

Near Distance (Color B) – Specifies the near distance value. Available when Falloff Type is set to Distance Blend.

Extrapolate – When enabled, the falloff effect continues beyond the Near and Far distances. Available when Falloff Type is set to Distance Blend.

 

Multipliers


 

 

 

Mode – Specifies the multiplication mode of the colors. 

Multiplier – Multiplies the RGB numbers for each pixel of the top layer with the RGB number of the corresponding pixel from the bottom layer. The result is a darker picture. 
Blend Amount  Takes each pixel from the top layer if present. Otherwise the bottom layer is used.

Color 1 – Controls the intensity of the front color.

Color 2 – Controls the intensity of the side color.
