The Radial Ramp tool lets you create images with a variety of properties and in several formats. The Radial Ramp tool has three sets of color channel value fields that allow you to generate a multi-color image based on RGBA values. One set of values is for generating the fill color, and two sets are for generating start and end radially ramped colors arranged around a central axis region of definition (ROD). The fill color is defined as those pixels residing outside the ROD. Other controls let you to position the X and Y axes of the central ramp at any location, stretch the ramp vertically or horizontally, and define the falloff center point and range.

To create a radially ramped image using the Radial Ramp tool:

1. Drag the Radial Ramp tool from the Tools tab to the dependency graph in the Schematic view and attach it to the Output node.

   

2. Apply image properties—see Setting Image Generation Properties and Formats.
3. Adjust the color values in the Fill, Start, and End fields.
4. Modify the location and direction of the X and Y ramps.
5. Adjust the middle and falloff ranges.

   

   NoteYou can also manipulate the radial ramps by left-clicking and moving them.
