??? The colored dots are not
randomly added for visual appeal, but to help you match the logical outputs of nodes to
inputs of other nodes.Using the outputs and inputs properly is what will define and determine
your final surface. Here??™s the breakdown of colors and what they mean:
?—? Red dots represent color operations.
?—? Blue dots represent vector operations.Vector operations control attributes such as
Scale, Position, or Bumps.
?—? Green dots represent scalar operations, which govern attributes such as
Luminosity, Glossiness, and Alpha channels.
?—? Yellow dots represent functions. Functions are mathematically based controls for
attributes such as Noise; they are used to drive the shape, pattern, or configurations
of other nodes. A Noise node might be used to randomize the texture of a
Marble or Turbulence node, for instance.
?—? Purple dots represent integers. Integer operations are used mainly for specifying a
choice from a numbered list of node options.Nodes that feature color-blending
functions, for instance, offer 14 blending-mode options, numbered 0 to 13, and an
integer operation is used to specify the number of the mode that should be applied.
