c4d.plugins.SceneLoaderData

class c4d.plugins.SceneLoaderData
A data class for creating scene loaders.
Use RegisterSceneLoaderPlugin() to register the plugin.

Note

Before you start writing your own SceneLoaderData plugin, you should read NodeData Manual before.

Methods Signatures

SceneLoaderData.Identify(self, node, name, ...)

Override - Identify the file type as one that can be loaded using this plugin.

SceneLoaderData.Load(self, node, name, doc, ...)

Override - Load the file into the document.

Methods Documentation

SceneLoaderData.Identify(self, node, name, probe, size)
Override - Identify the file type as one that can be loaded using this plugin.

If possible, the file should not be identified through the suffix, but through the probe data.
Parameters
  • node (c4d.BaseList2D) – The node object.

  • name (str) – The name of the loader.

  • probe (memoryview) – The start of a small chunk of data from the start of the file for testing this file type. Usually the probe size is 1024 bytes. Never call the buffer outside this method!

  • size (int) – The size of the chunk for testing this file type.

Return type

bool

Returns

True if your plugin recognises this file.

SceneLoaderData.Load(self, node, name, doc, filterflags, error, bt)

Override - Load the file into the document.

Parameters
  • node (c4d.BaseList2D) – The node object.

  • name (str) – The filename of the file to load.

  • doc (c4d.documents.BaseDocument) – The document that the selected objects should be loaded into.

  • filterflags (int) –

    Information about what can be done during this load call:

    SCENEFILTER_NONE

    None.

    SCENEFILTER_OBJECTS

    Load/save objects.

    SCENEFILTER_MATERIALS

    Load/save materials.

    SCENEFILTER_DIALOGSALLOWED

    Flag to inform a plugin that a dialog can be displayed. If this flag is not set then no dialogs must be opened.

    SCENEFILTER_PROGRESSALLOWED

    Flag to inform a plugin that a progress bar can be displayed. The progress bar can be set by calling StatusSetBar().

    SCENEFILTER_MERGESCENE

    Flag to inform a plugin that this is a merge operation, i.e. the document that is inserted to is an existing scene.

    SCENEFILTER_NONEWMARKERS

    Objects loaded from disk will keep their markers.

    SCENEFILTER_SAVECACHES

    For melange export only. Caches of objects will also be written (only supported by Cinema 4D format). This is the same as the global option “Save Polygon Objects for Melange Exchange”.

    SCENEFILTER_NOUNDO

    Use together with SCENEFILTER_MERGESCENE to avoid that undos are created for the merge operation.

    SCENEFILTER_SAVE_BINARYCACHE

    Save the binary compiled shaders with the scene (only for Cinema 4D format).

    SCENEFILTER_IDENTIFY_ONLY

    Do not load the whole document, identify it only.

    SCENEFILTER_ONLY_RENDERDATA

    Only load render settings. If this flag is set, SCENEFILTER_OBJECTS and SCENEFILTER_MATERIALS are ignored.

    SCENEFILTER_IGNOREMISSINGPLUGINSINNONACTIVERENDERDATA

    Ignore all missing plugins which are part of a non-active render data.

    SCENEFILTER_IGNOREXREFS

    New in version R16.038: Avoid that included X-Refs will be loaded.

    SCENEFILTER_DONTCORRECTOUTPUTFORMAT

    Do not change unknown output formats in render settings.

  • error (None) – Not supported.

  • bt (c4d.threading.BaseThread) – The calling thread.
