Gradient Range & Offset

The Range of a gradient is the distance in Bryce units that the gradient spans. When a gradient light is this distance from its source, the gradient's end color is applied to the light (provided you've accepted the default offset value of zero).

The Offset of a gradient determines how the gradient colors will be applied to the light source. By default, the offset value is zero, which means that the light will start with the start colors of the gradient. When you increase the offset, intermediary gradient colors will be applied to the light at its source. The maximum offset value of 100 results in a light source which begins with the end color of the gradient. See the last image on this page for an example of the Offset set to 100.

To change a gradient's Range in the Light Lab, click the Range control in the Color area, and type a value in the field. The Range can be set from 0 to 99,999.

To change a gradient's Offset in the Light Lab, click the Offset control in the Color area, and type a value in the field. The Offset can be set from 0 to 100.

You can also change a gradient's Offset by dragging the Offset button next to the Gradient preview.

Examples:

Range = 51.2; Offset = 0:
Range = 25; Offset = 0;
Range = 100; Offset = 0:
Range = 100; Offset = 25:
Range = 100; Offset = 50:
Range = 100; Offset = 55 - showing the center still a bit green, then changing to orange:
