Gradient (Light)

Python: "map_gradient_light"

The gradient_light map uses an HDR spline profile to define colors across a line, a polygon, or a circle. Some additional controls are provided to create a pattern over the UV plane.

Defines the primary (background) color. The lower end of the output signal range is remapped to this color.

Primary color map

Python: "map_color_1_map"

Defines the primary color using a texture map.

Secondary color

Python: "map_color_2"

Defines the secondary (foreground) color. The upper end of the output signal range is remapped to this color.

Secondary color map

Vignette

Vignetting hardness

Python: "map_gradient_vignette_hardness"

Amount of noise distortion applied to the UVs before they are used.

Noise size

Amplitude of the noise distortion. This value is given in UVW space; e.g., 0.1 means that the maximum distortion is about 1/10th of a 1x1x1 texture tile.
