Enabling RenderDoc Plugin

The RenderDoc plugin does not need to be enabled to use RenderDoc with an Unreal Engine project. The standalone RenderDoc works with the UE executable. See RenderDoc Documentation to follow their setup guide.

Unreal Engine provides a plugin that makes it easy perform a next-frame capture from within the Editor and automatically open that in RenderDoc. Use the steps below to enable it in your project:

  1. Navigate to the main menu and select Edit > Plugins to open the Plugins browser.

  2. You can find the RenderDoc Plugin under the Rendering category, or simply use the search bar at the top of the Plugins browser window.


  3. Place a check in the box next to Enabled, and when prompted, restart the editor.

Once the Editor restarts, the Level Viewport will contain a new UI button on the top right. You can use this to perform a capture.


Performing a Frame Capture

The steps below describe at a high level how to perform a single-frame capture with your Unreal Engine project using the integrated RenderDoc plugin or directly from RenderDoc application.

Further details on functionality and use of RenderDoc can be found in RenderDoc Documentation.

RenderDoc Plugin

The following steps are used to capture a frame using Unreal Engine's RenderDoc Plugin:

  1. Enable the RenderDoc plugin for your project.

  2. Open your project and scene where you want to perform a capture.

  3. Click the RenderDoc Capture button in the Level Viewport.

    Click image for full size.

RenderDoc Application

The following are the high-level steps required to capture a frame using Unreal Engine with the standalone RenderDoc executable:

  1. Configure RenderDoc to launch your game or the UEEditor.exe with the appropriate command line arguments.

    Enable Capture Child Processes when launching with the UEEditor.exe.

  2. Launch the executable.

  3. Press the F12 hotkey to perform a frame capture.

For full details on setting up RenderDoc, launching an application and performing a frame capture, see the RenderDoc Getting Started Guide.

Project Settings

Use the Project Settings window to set additional RenderDoc Plugin settings. From the main menu, select Edit > Project Settings and then under the Plugins category, select RenderDoc.




Frame Capture Settings

Capture all activity

When enabled, RenderDoc captures all activity in all viewports and Editor windows for the entire frame instead of only the current viewport.

Capture all call stacks

When enabled, RenderDoc captures call stacks for all API calls.

Reference all resources

When enabled, RenderDoc includes all rendering resources in the capture, even those that have not been used during the frame.

Enabling this property will significantly increase capture size.

Save all initial states

When enabled, RenderDoc always captures the initial state of all rendering resources, even if they are not likely to be used during the frame.

Enabling this property will significantly increase capture size.

Advanced Settings

Show help on startup

When enabled, a help window with RenderDoc is shown on Editor startup.

Use the RenderDoc crash handler

If enabled, the RenderDoc crash handler is used if a crash occurs.

This should only be used if you know the problem is with the RenderDoc application and would like to notify the RenderDoc developers.

RenderDoc executable path

Sets the path to the RenderDoc executable to use.

This should automatically fill in when with the correct path when RenderDoc is installed.
