Cellular noise: This node uses the Voronoï
regions to sample points across the terrain that act like
mini-generator diffusing an elevation around them, thus creating
cell-like structures.
Constant elevation node: This node creates
flat ground whose width, height, quad size, and altitude are
defined.
Color
blend: This node creates an alpha composition between
two color maps at locations defined by a mask.
Color ramp to color map: This node takes an input
terrain with a color ramp and outputs a color map.
Viewing color maps: When you click on an
Extract color map or Alpha
blend node that outputs a color map, the color map is
shown as a
plane image in the 3D view.
Color ramp
picker: The color ramp node now has a Pick color
gradient option that allows you to draw a segment anywhere on the
screen, including outside the Instant Terra window. A color ramp is
automatically created from the colors under the segment.
