Advanced Preview Settings

Adjust Lighting

It is possible to add a new In-Game Light Settings Profile from an existing Unreal Engine ULevel Asset. By clicking on the Add New Profile Button, in the lower part of the Preview Scene Settings, an Asset Browser will show up. After selecting a level a new window will appear and ask which lights will be used to make the profile. The new profile is added to the Scene Profiles and can be selected from the profiles dropdown.

The selected ULevel must have at least one DirectionalLight, one SkyLight and one PostProcessVolume actors. The information in those actors will be used to make the new profile. If such a ULevel Asset does not exist, a new one must be created by clicking on "File/New Level" (at the main page, outside the Customizable Object's tab) and at least those three actors named above are to be dragged and dropped into it. Then this level must be named and saved in order to appear on the Asset Browser's list.

Add Multiple Lights

Additionally, multiple lights can be added to the viewport using the Lighting options in the Custom Settings section. This feature allows users to create, edit, save and load sets of lights to further improve the lighting from the preview scene.
