The Property Matrix allows for easy bulk editing and value comparison 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 that can be sorted on any column. The Property Matrix also provides a standard property editor that displays all properties for the current selection set in the table view.

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.

  • Even handles ARRAY INDICES.

Accessing the Property Matrix

There are currently two ways you can access the Property Matrix :

  • The Property Matrix button available in the Details panel adjacent to the Search box will launch a Property Matrix bound with your current selection.

Using the Property Matrix

The Property Matrix is effectively a table and handles much 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

The user can add and remove columns by pinning and unpinning properties in the property tree to the right of the table.

Pin properties to add columns

Columns can also be removed through the drop down menus in column headers or by middle-clicking the column header itself.

The Property Matrix will attempt to auto-populate the table with useful columns, based on the types of objects bound to the table.

Editing Properties

Most cells just display their bound value as text and allow the user to 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.

One great feature of the Property Matrix is that it lets you compare property values deep in an object.

The property table can even handle array indices!!

The Property Tree on the right of the table is bound to the selected rows in the table. This allows the Property Matrix to handle editing a wide variety of types at the same time!

Sorting

The user can also sort any column in ascending or descending order by simply clicking on the column header. An arrow will appear on the header to let you know which way the column is sorted.
