Ramp

Creates a gradation through a series of colors. Use this texture:

• to create different types of effects, such as stripes, geometric patterns, or mottled surfaces
• as a 2D background
• as the source file for an environmental sphere texture to simulate a sky and horizon
• as the source file for a projection texture to simulate wood grain, marble, or rock

Find this texture in the Create tab. To apply this texture as a texture map, see Map a 2D or 3D texture.

Note:

Very complex ramp textures may experience aliasing during an animation. If this occurs, convert the ramp texture into an image file (see Convert a texture or shading network to a File Texture for details).

Type

The direction of the color ramp. The default is V Ramp. The following shows what happens when you select the Circular Type and adjust the colors of the Ramp swatch in the Attribute Editor (see also Ramp below).

Interpolation

See Interpolation for more information.

Ramp

By default, the Ramp is set to black and white (from black to white).

You can switch over to a rainbow ramp by selecting Presets > Rainbow. To revert back to the default, select Presets > BlackToWhite. Another available option is Presets > WhiteToBlack.

See Color ramp for more information on how to customize your ramp by adding additional color entries.

Note: Only changes in Interpolation, Selected Position, and Selected Color are displayed in the ramp. Changes to all attributes are displayed in the Hypershade swatch.

Advanced ramp features exist. For more information, see Ramp Shader.

Selected Color

The active color component. This attribute applies to the active color only.

Selected Position

Position of the active color component in the ramp. This attribute applies to the active color only. The range is 0 (bottom of ramp) to 1 (top of ramp).

U Wave, V Wave

Controls the amplitude of a sine wave offset of the texture in the U and V directions. Increasing the U Wave or V Wave increases the display of the texture’s waviness. The range is 0 (no wave) to 1. The default is 0.

Tip:

To increase the number of waves in the texture, increase the Repeat UV values in the 2D texture placement node.

Noise

Offset amount in the U and V directions by 2D noise. If the texture repeats (Repeat UV values are greater than 1), the noise does not repeat (each instance of the texture is unique). The range is 0 (no noise) to 1. The default is 0.

Noise Freq

Controls the noise granularity (if the Noise value, above, is non-zero). The range is 0 to 1. The default is 0.5.

HSV Color Noise

Randomize a Ramp texture’s color using three separate 2D noises which affect the color’s Hue, Saturation, and Value.

Hue Noise

Offsets the color hue. Use to mark the color with specks of different colors. The range is 0 to 1. The default is 0.

Sat Noise

Offsets the color saturation (or whiteness). Use to create a weathered look. The range is 0 to 1. The default is 0.

Val Noise

Offsets the color value (or blackness). The range is 0 to 1. The default is 0.

Hue Noise Freq, Sat Noise Freq, Val Noise Freq

Controls the granularity for hue, saturation, and value noise. The range is 0 to 1. The default is 0.5. (For each non-zero Freq value, additional calculations may slow down rendering.)
