By default, the [Product Structure](./_index.md) displays the name of the occurrences and their visibility.

In order to gain efficiency while reviewing the scene, the user can display further information regarding the occurrences listed in the tree through Fast Properties.

## About Fast Properties

Each occurrence carries properties (see [About Occurrences](../../../data-preparation-fundamentals/about-occurrences) and [Occurrence Properties](../../../data-preparation-fundamentals/about-occurrences/occurrence-properties) for more information).

Each property (among `ID`, `Name`, `Visible`, `Material`, `Transform`, `Prototype`, or `Custom Property`) can be made visible in the Product Structure, by making it a Fast Property, added as a column.

The column displays the property's value for each occurrence of the tree.

> **Important:**
>
> Displaying a lot of Fast Properties for scenes with a very large number of occurrences may impact the fluidity of navigation in the scene.

## Displaying a Fast Property
