```

```
Visible
```

```
Material

: Defines the material assigned to the occurrence
```
Transform
```
: Defines the position of the occurrence in the scene (transformation matrix)

A CAD/3D model can contain occurrences in its Product Structure that carry additional, non-geometric data, often called metadata in the CAD world.

These metadata were added to the CAD model directly in the software where it was created, and are retrieved at import in Asset Transformer Studio.

They are stored as properties in the Metadata Component, which is automatically created at import.

Custom properties

can be added to an occurrence by the user through the user interface (Inspector panel) or using Python scripting.

Note

Custom Properties are listed in the

Other Properties

folder of the Inspector panel.
