c4d.NodeMaterial

class c4d.NodeMaterial
The node-based material with the Mbase type.
This class is a collection of accessors to node-related functionality that are grouped for clarity purposes.
Note that any c4d.BaseMaterial can be elevated to a c4d.NodeMaterial, no special construction is needed.

New in version S24.

Returns

Returns True if the node space exists, False otherwise.

Return type

bool

NodeMaterial.GetMaterialNodePath(self, spaceId)

Returns the node path to the material end node.

Parameters

spaceId (maxon.Id) – The id of the node space.

Returns

The path to the material end node.

Return type

maxon.frameworks.graph.NodePath

NodeMaterial.GetSoloNodePath(self, spaceId)

Returns the node path to the solo node.

Parameters

spaceId (maxon.Id) – The id of the node space.

Returns

The path to the solo node, empty if nothing was soloed.

Return type

Static Methods Documentation

static c4d.NodeMaterial.GetTextureSearchPaths(secondaryPath, documentPath)

Determines the paths pointing to directories that are used to reference images by relative path in a particular c4d.documents.BaseDocument.

>>> doc = c4d.documents.GetActiveDocument()
>>> secondaryPath = maxon.Url(doc.GetDataInstance()[c4d.DOCUMENT_SECONDARYPATH])
>>> docPath = maxon.Url(doc.GetDocumentPath())
>>> docPath
file:///C:/Users/m_adam/Documents

>>> textureSearchPaths = c4d.NodeMaterial.GetTextureSearchPaths(secondaryPath, docPath)
>>> for path in textureSearchPaths:
...     print(path)

Note

The returned BaseMaterial is only safe for access in the usual places of the API.
You must avoid to perform read or write access to it in an arbitrary worker thread.
Parameters

graph (maxon.frameworks.nodes.NodesGraphModelRef) – The node graph of the owner.

Returns

Returns the owner of the node graph, None if unknown or on failure to retrieve.

Return type

c4d.BaseMaterial
