Overview
A DlShadingNode represents a 3Delight OSL shader. By connecting many DlShadingNodes together, a shading network can be defined, which ultimately is connected to a Katana Network Material node.
Clicking on the down arrow next to nodeType will display a list of available OSL shaders. Selecting one shader in the list will populate the parameters section below with the shader attributes.
In the Node Graph, clicking on the arrow on the right end will display the list of available incoming ports for this shader. Clicking the arrow on the left end will show available output ports. Note that input parameters can also be used as output ports; their value is simply passed to the outgoing connection.
