GLTFDocumentExtension

Inherits: Resource < RefCounted < Object

Inherited By: GLTFDocumentExtensionConvertImporterMesh

GLTFDocument extension class.

Description

Extends the functionality of the GLTFDocument class by allowing you to run arbitrary code at various stages of GLTF import or export.

To use, make a new class extending GLTFDocumentExtension, override any methods you need, make an instance of your class, and register it using GLTFDocument.register_gltf_document_extension.

Note: Like GLTFDocument itself, all GLTFDocumentExtension classes must be stateless in order to function properly. If you need to store data, use the set_additional_data and get_additional_data methods in GLTFState or GLTFNode.
