The Gradient node is a very useful starting primitive, especially when displaced or modified to create randomness. It is also a very useful mask generator.
This primitive creates three distinct types of gradients: Linear, Radial, and Helix. Several properties shown below are unique to each gradient type.
|Type||LinearA ramp going from lowest to highest. RadialA soft, radial "bump". HelixA climbing spiral or Helix gradient.|
|Scale||The scale of the gradient.|
|Direction||The angle of the Linear gradient.|
|Edge Behavior||NoneEdge pixels are left blank. MirrorEdge pixels are mirrored. RepeatEdge pixels are repeated. Edge|
|X||Horizontal placement of the Gradient.|
|Y||Vertical placement of the Gradient.|
|Start||Where the Helix will start.|
|End||Where the Helix will end.|
