```csharp
[InspectorName("Standard (Legacy)")]
[Tooltip("Use the standard Material import method.")]
ImportStandard = 1
```

When selected, the model importer generates and populates materials by applying a set of simple default rules. The ModelImporter will also invoke AssetPostprocessor.OnPostprocessMaterial with each created material. Note: This is the only option where OnPostprocessMaterial is called.
