Scale

  The amount by which to scale the heights values: increase or decrease bumps.

  Scale = 2

X Component, Y Component

  The component used for X, Y coordinates: you can choose between the three RGB colors for the bumps.

  Note that if you change these values, new colors are added to the existing colors, giving the complementary colors.

Flip X, Flip Y

  Flip the X, Y coordinates: flip bumps colors, horizontally and vertically. Bumps have a clear border and an opposite dark border, giving a feeling that light comes from a certain direction. To see bumps instead of hollows, light must come from the upper left corner; play with Flip X and Flip Y to get this lighting.

  After playing with Flip X and Flip Y

Full Z Range

  Use the full [0, 1] range to encode the Z coordinates: You can get a more abrupt color gradient.
