When none of the above metadata are provided, the parameter name is used directly to define the attribute name.
string label
Specifies the label of the widget that controls the attribute.
float min, float max
int min, int max
Specifies the minimum and maximum values allowed for the attribute. In Katana, this defines the slider range, as an attribute value cannot be bounded.
string niceName
Maya-specific
Specifies the attribute name to use in the user interface, when possible. This will be used in the Maya editors, notably the Node Editor and the Channel Box. It will also be used for the automatically generated Attribute Editor template, unless label is specified.
string options
This metadata provides extra options. The enumeration list and values for a type set to enum or a widget set to mapper is expected to be defined using this metadata. The expected format is a list of labels, optionally with values, separated by a |. For instance:
| Code Block |
|---|
string options =
"Euclidean:0|"
"Manhattan:1|"
"Chebyshev:2|"
"Minkowski:3|" |
string page
Defines the name of a group under which the widget of the attribute will be placed.
float slidermin, float slidermax
int slidermin, int slidermax
Specifies the range of of the slider widget that controls the attribute. This is ignored in Katana.
string type
Specifies the type of the attribute related to this shader parameter. By default, the attribute type is derived from the parameter type and the widget type.

Valid for integer shader parameters. The enumeration list should be set using the options metadata.
message
Maya-specific
. Valid for string shader parameters. A message attribute will be created and the connected node's name will be passed as this shader parameter's value.
string label
Specifies the label of the widget that controls the attribute.
string widget
Defines the type of widget to control the attribute's value. mapper
