Shader Inputs

Each connectable input parameter for a shader can declare what tag values it requires for a connection to be valid.

The user interface makes use of these declarations to only allow the user to make valid connections.

Tag values for an input input parameter are declared in .args files with the following syntax:

<tags>

</tags>

</param>

</args>

The following is the equivalent hint dictionary syntax:

{"PrmanShadingNode.parameters.diffStr": {

"widget": "null",

"name": "diffStr",

"transientHints": {"helpCaption": true},

"tags": ["color and diffuse"],

"helpCaption": "shader: MyShaderName - diffStr",

"coshaderPort": "True"

}

Logical Inputs

Boolean logic is available to make more advanced rules specifying which connections are valid for any input

parameter. The available operators are and, or, not, ( ', ' )

AND

<tags>

</tags>

</param>
