Syntax

class UInterchangeBaseNodeContainer : public UObject

Remarks

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
