Functions Documentation

c4d.modules.substance.ImportSubstance(doc, fn, copyFile, errPopup, addUndo, createMaterial)

Imports a Substance asset file (.sbsar) into doc.

Parameters

• doc (c4d.documents.BaseDocument) – The document to import into.

• fn (str) – The Substance asset file.

• copyFile (int) –

  The copy file flag:

  SUBSTANCE_IMPORT_COPY_YES	Automatically copy file to project directory (relative file path).
  SUBSTANCE_IMPORT_COPY_NO	Do not copy file to project directory (absolute file path).
  SUBSTANCE_IMPORT_COPY_ASK	Ask user.

  If set to ASK, user’s choice will be returned.

  Note: When set to ASK, the function obviously has to be called in a context where user interaction is allowed.

• errPopup (bool) –

  If set to True, problems will be communicated to the user with a message requester.

  Note: When set to True, the function obviously has to be called in a context where user interaction is allowed.

• addUndo (bool) – If set to True, an undo step will be added for the import. Caller has to care for the surrounding BaseDocument.StartUndo() and BaseDocument.EndUndo() calls.

• createMaterial (bool) – Set to True, to have a material created based on the configuration in preferences. Set to False, to suppress any creation of materials.

Return type

Tuple[int, c4d.BaseList2D, int]

Returns

A tuple with the following information:

int: The result for the import:

SUBSTANCE_IMPORT_RESULT_SUCCESS	Success.
