Property Matrix in Unreal Engine | Unreal Engine 5.3 Documentation

While working in a level with multiple actors, updating individual properties at once can become time-consuming. You can use the Property Matrix to complete bulk edits and compare values for large numbers of objects or actors. It displays a configurable set of properties for a collection of objects as columns in a table view. The Property Matrix also provides a standard property editor that displays all properties for the current selection set.

Features

Feature	Benefits
Bulk Object Editing	Easier workflow for setting a series of varying values to a bunch of objects, without sacrificing the ability to set the property on a bunch of objects to the same value. Works with thousands of objects at the same time. Can handle editing a wide variety of object types at the same time.
Bulk Fine-Grain Object Comparison	Sort the values on thousands of objects at a time. Quickly find assets and Actors with incorrect settings.
Deep Property and Array Support	Do all of the above with the properties of arrays and struct types. Can expose columns for any property. Handles array indices.

Accessing the Property Matrix

You can access the Property Matrix by:

Select the Property Matrix button in the Details panel adjacent to the Search bar.
In the Content Browser, make a selection of assets, right-click, choose Asset Actions, then choose Edit Selection in Property Matrix from the context menu.
In the Outliner, right-click your selection, then choose Edit Selection in Property Matrix from the context menu.
In the Outliner, right-click your selection, then choose Edit Components in the Property Matrix to select any shared component types from the context menu.

Using the Property Matrix

The Property Matrix is a table that handles data like other grid-based editors. All cells have two modes: Display and Edit. Depending on the current mode, the cells' feature set changes.

Adding and Removing Columns

You can add and remove columns by pinning and unpinning properties in the Pinned Columns panel. The list of properties in the panel is referred to as the property tree.

Columns can also be removed by right-clicking the column headers or by middle-clicking the column header itself.

The Property Matrix attempts to auto-populate the table with valuable columns based on the types of objects bound to the table.

Editing Properties

Most cells display their bound value as text and lets you edit the text representation, but cells are fully customizable by the programmer and can vary greatly. For example, some cells have completely custom cell implementation such as boolean and color values.

The property tree is bound to the selected rows in the table. This bounding means the changes you make to the properties are only applied to the selected items.

While in the table, settings are applied to the last cell you select.

You can also copy selected cells and paste them to relative settings in the table.

Additional editing features include:

Comparing property values deep in an object.
The handling of array indices.

To view the path of a property in your column, hover the cursor over the header name.

Your level updates as properties are changed; however, you must click the save icon to apply the settings officially.

Sorting

You can sort columns in ascending or descending order by clicking the column header. An arrow appears on the header to tell you how the column is sorted.
