Renderer settings

Change renderer project settings that stay after an editor restart.

What it’s for

This area changes your project’s renderer settings, the ones under Project Settings → Engine → Rendering. Changes are saved to Config/DefaultEngine.ini, so they show up in Project Settings and stay after you restart the editor.

Ask for it when a renderer change should stick: switching global illumination to Lumen, turning on hardware ray tracing, choosing a reflection method, or any other saved rendering option.

For a quick change that only lasts for the current session, your assistant uses Builds, tests and jobs, Lighting or Screenshots and captures instead. Some settings here also update the viewport right away while saving the value.

Things you can ask

Check the current renderer settings

You see what is set now, before anything changes.

You: Show me the current Lumen-related rendering settings.

Here are the Lumen settings from DefaultEngine.ini. Hardware ray tracing for Lumen is off.

Switch global illumination to Lumen

The project uses Lumen GI, the viewport updates, and the setting is saved.

You: Set global illumination to Lumen for the project.

Global illumination is now Lumen. The viewport updated and the setting is saved to DefaultEngine.ini.

Turn on hardware ray tracing for Lumen

Lumen uses hardware ray tracing and Lumen reflections, saved to the project.

You: Enable hardware ray tracing for Lumen and use Lumen reflections.

Hardware ray tracing for Lumen and Lumen reflections are on, and saved to DefaultEngine.ini.
