unreal.InterchangeBaseNode

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

Bases: unreal.Object

This struct is used to store and retrieve key value attributes. The attributes are store in a generic FAttributeStorage which serialize the value in a TArray64<uint8> See UE::Interchange::EAttributeTypes to know the supported template types This is an abstract class. This is the base class of the interchange node graph format, all class in this format should derive from this class
