Members

Plugs:

string Code RW The shader node default BOOTS code

nil removeinput ( string name ) Remove an input
nil removeoutput ( string name ) Remove an output

Inherited from class SelectableNode

Plugs:

boolean Selected R True if the node is selected. Don't use this plug directly to select a node, use the Document's modifier select method.
