unreal.InterchangeBaseNodeContainer

class unreal.InterchangeBaseNodeContainer(outer=None, name='None')

Bases: unreal.Object

Interchange UInterchangeBaseNode graph is a format used to feed asset/scene import/reimport/export factories/writer. This container hold a flat list of all nodes that have been translated from the source data.

Translators are filling this container and the Import/Export managers are reading it to execute the import/export process

C++ Source:

  • Module: InterchangeCore

  • File: InterchangeBaseNodeContainer.h

add_node(node) → str

Add a node in the container, the node will be add into a TMap. return:: return the node unique ID of the added item. If the node already exist it will return the existing ID. Return InvalidNodeUid if the node cannot be added.

Parameters

node (InterchangeBaseNode) – a pointer on the node you want to add

Return type

str
