The following sections describe these areas and the additional tabs in more detail.

Asset Status

The Asset Status table displays the status of assets that Lumberyard is processing. Select a row to display contextual asset processing information in the Event Log Details table.

The columns in the Asset Status table display the following information about each asset:

  • Source – Asset's file name and location

  • Completed – Timestamp of the process completion

  • Platform – Game platform

  • Job Key – Specific job process

                    The Asset Status table displays specific
                        information about assets in each column.

Status Column

In the Status column, you can sort by status types.

The column headers display the following information about each asset:

  • Completed – Completely processed and converted for use in the game

  • Failed – Failed and needs investigation and debugging

  • In Process – Currently processing and will display Completed or Failed when complete

  • Pending – Awaiting processing

Filtering by Keyword and Status

In the filter box, you can filter the table view by entering keywords and regular expressions. The regular expressions are standard std::regex in extended format. The standard std::regex rules apply.

A regular expression (regex) to search for all files ending with .png:


The asterisk (*) indicates any character 0 or more times.

A regex to search for any files under a Slices subdirectory:


The dot plus (.+) indicates any character 1 or more times.

To view all assets with a particular status, do one of the following:

  • Type the status keyword (for example, "failed").

  • Click the filter icon and select the status types that you want to see.

Filters that you apply remain active until you remove them. You can either clear the status type box, or click the X next to the filter's label.

                        Filter the Asset Status table using keywords or
                            regular expressions. Remove filters by clearing the status type box or
                            removing the label.

Using a Row's Context Menu

You can perform actions on each row in the Asset Status table. Right-click on the row to expose a context menu with the following actions:

                        Right-click on a row to expose the context menu in the
                                Asset Table.

The Status column displays icons for the following message types:

                                Error icon in Status table.

Additional supporting messages are available about the processing of the asset.

                                Warning icon in Status table.

See the Message column for information about a potential processing issue for this asset.

The Source column indicates the subsystem that generated the message (such as AssetBuilder) or a generic type, such as Warning or Error.

The Message column displays information related to the processing details of the selected asset.


The Message column occasionally prefixes Errors with E: and warnings with W:.

The Shaders tab displays a table with information related to shader compiler proxies. Shader failures appear in this table. For more information, see Shader Compiler Proxy.


The Connections tab displays devices and programs that the Asset Processor is connected to and the platform they are running on. You can add approved connections in the White Listed Connections box and disapproved connections in Rejected Connections.

In the Active Connections table's Enabled column, automatic connections are labeled as Auto. This means that it's a connection that the Asset Processor created. One example of such a connection is Asset Builder connections. User-created connections show a check box. If you select the check box, the Asset Processor continually attempts to reconnect to those connections. You can use these custom connections for specialized cases, such as when connecting to mobile devices outside of a company's internal network.

                    Connections tab in the Asset Processor.

You can edit or remove a user-created connection, or add a connection.

                    Edit a user-created connection in Asset Processor.


The Logs tab displays events for the internal operation of the Asset Processor. This area doesn't display logs for the processing of individual assets. The information in these logs is helpful for troubleshooting the Asset Processor if an issue occurs.

                    Logs tab in Asset Processor.

Right-click to access the Logs context menu.

                    Logs tab context menu in
                        Asset Processor.


On the Tools tab, you control how your assets are scanned. Use Faster Scanning Mode when you don't need to perform a full asset scan. For more information, see Enabling Asset Processor's Faster Scanning Mode.
