• String Array

An array of string objects. Requires name and size arguments.

Top Level User Parameters

As covered in Getting the Parameters of a Node the node parameters that you see at the top level in a node’s

Parameters tab are all children of the node’s root parameter. User Parameters on a node are also added as children

of the root parameter. For example, to create a new PrimitiveCreate node, and add a User Parameter of type

number, enter the following:

# Get the root node

root = NodegraphAPI.GetRootNode()

# Add a PrimitiveCreate node at root level

node = NodegraphAPI.CreateNode( 'PrimitiveCreate', root )

# Get the PrimitiveCreate node's root parameter

rootParam = node.getParameters()

# Add a User Parameter of type number

numberParam = rootParam.createChildNumber( "Foo", 123.0 )

Nested User Parameters

Complex hierachies of User Parameters are possible, by nesting User Parameters under Group User Parameters. For

example, create a new PrimitiveCreate node, and add a User Parameter of type number, nested under a User

Parameter of type Group:

# Get the root node

root = NodegraphAPI.GetRootNode()

# Add a PrimitiveCreate node at root level

node = NodegraphAPI.CreateNode( 'PrimitiveCreate', root )

# Get the PrimitiveCreate node's root parameter

rootParam = node.getParameters()

# Add a User Parameter of type Group under the root parameter

groupParam = rootParam.createChildGroup( "yourGroup" )

# Add a User Parameter of type Number under the group

numberParam = groupParam.createChildNumber( "yourNumber",\

123.00 )

Parameter Hints

Parameter hints are arbitrary metadata, most commonly used to tell the user interface what a User Parameter

contains. For example, add a User Parameter of type string to represent a file path to an asset, and use a hint to tell

Katana to use the asset browser widget for that User Parameter:
