Grad
The Grad node generates a gradient between four corners of different colors. The count
order of the corners is: Corner 1 in the lower-left corner, corner 2 in the lower-right
corner, and so on. For a simple gradient ramp, use the Ramp node. For a radial gradient,
use the RGrad node.
Parameters
This node displays the following controls in the Parameters tab:
width, height
The width and height value fields in the Res parameter set the size of the generated
image.
bytes
The bit depth of the generated image. There are three settings: 8 bits, 16 bits, or float
(1, 2, or 4 bytes per channel).
xMid, yMid
The midpoint of the gradient, where all four colors meet.
LLColor, aLL, zLL
The color, alpha channel value, and Z channel value at the lower-left corner. The color
defaults to 100 percent red.
LRColor, aLR, zLR
The color, alpha channel value, and Z channel value at the lower-right corner. The color
defaults to 100 percent green.
