Detailed Description

Describes a connection between two nodes in a material.

A brief discussion of terminology follows:

  • Shading nodes have inputs and outputs.
  • Shading nodes consume input values and produce output values.
  • Connections also have inputs and outputs.
  • Connections consume a value from the (inputId, inputName) and pass that value to the (outputId, outputName).

Note that a connection's input is considered an output on the upstream shading node, and the connection's output is an input on the downstream shading node.

A guideline to remember this terminology is that inputs are always upstream of outputs in the dataflow.
