{
  BaseMaterial* mat = static_cast<BaseMaterial*>(node);
  BaseContainer* data = mat->GetDataInstance();
 
  switch (id[0].id)
  {
  case SIMPLEMATERIAL_MAT_PREVIEW:
    return GetDParameterPreview(data, &t_data, flags, SIMPLEMATERIAL_MAT_PREVIEW, updatecount, mat);
  }
 
  return MaterialData::GetDParameter(node, id, t_data, flags);
}

Parameters

[in]	pContainer	The container of the node sent to NodeData::GetDParameter(). The caller owns the pointed container.
[in]	pData	The t_data sent to NodeData::GetDParameter(). The caller owns the pointed data..
[in]	lFlags	The flags sent to NodeData::GetDParameter().
[in]	lID	The ID of the material preview.
[in]	lCount	The dirty count.
[in]	pMaterial	The material. The caller owns the pointed material.

Returns

true if successful, otherwise false.

	)

Convenience function to use in NodeData::GetDParameter() of shader nodes with a material preview in the description:

Bool SimpleShader::GetDParameter(GeListNode *node, const DescID &id, GeData &t_data, DESCFLAGS_GET &flags)
{
  BaseShader* shd = static_cast<BaseMaterial*>(node);
