NOTE: The widget type of a parameter can also be defined by setting a widget hint string. See Parameter

Hints for more on this.

Katana also has a dynamic array widget type, added to support shaders with dynamic array parameters. The

dynamic array widget type is not accessible through the UI. For more on using dynamic arrays in your shaders see
