How to Create a Gradient Ramp Texture in Maya
The ramp texture is a quick way to create gradients. You can specify the color(s), distortion and gradient type. Colorful ramps can be added to your color channel and grayscale versions work well in defining transparency or reflection.
Open a scene with a polygon plane primitive. Right click the object and choose Assign New Material > Lambert.
The new Lambert texture panel opens in the Attribute Editor. Click the checker-box in the Color section.
In the Create Render Node palette, right-click the Ramp icon in the 2D Textures section and choose Create Texture. This creates a file texture that is UV mapped to the object.
The Ramp Dialog box appears in the Attribute Editor. By clicking on a circle, you can select the color. Once a color is chosen, click the Selected Color rectangle and the color picker appears. Clicking on a square removes a color.
To add a new color, Left Mouse click the color sample box. Click on a circle, then adjust the Selected Position slider to move the color up or down.
The lower four sliders control the noise and distortion for the gradient.
The Type and Interpolation pull down menus offer a variety of patterns.
