We've now configured the level for Enlighten. The changes you made affect the actors included in the Enlighten computations. The effect on the Enlighten lighting isn't visible until you run the Enlighten precompute.

From the Build menu, select Build Enlighten > Precompute > All levels to run the precompute.

The precompute should take only a few minutes.
After the precompute finishes, from the Show menu, select Use Defaults to show the level with the default editor visualizations.
Press Ctrl + H to make sure no actors are hidden.
In the Show menu, under Lighting Components, disable Ambient Occlusion.

Ambient occlusion darkens areas of the image. Disabling it makes the effects of Enlighten easier to see.
Select View Mode > Lighting Only to show only the lighting in the level.

As in the See what Enlighten can do in Unreal tutorial, the direct lighting in the level comes from the DirectionalLight actor. Enlighten handles only the indirect lighting (the light from the sky and the reflected light visible in shadowed areas).
In the Show menu, under Lighting Features, disable Enlighten Indirect Lighting.

Enlighten Indirect Lighting on	Enlighten Indirect Lighting off

Objects reflect light, creating realistic gradients of light and dark. This indirect lighting is handled by Enlighten.	The lit areas are illuminated by the DirectionalLight. Areas the DirectionalLight doesn't reach are completely black.

You can enable and disable Enlighten Indirect Lighting to understand which parts of the lighting are handled by Enlighten.
For example, if you want to make an area brighter or darker, you can use the Enlighten Indirect Lighting to see how much of its lighting is handled by Enlighten, and make adjustments as necessary.

In the Show menu, re-enable Lighting Features > Enlighten Indirect Lighting.
In the World Outliner, double-click the actor Props_Awning_6 to focus on it.

The wall under the awning uses high lightmap quality, which is sufficient to capture the soft shadow under the awning.
Lighting Quality mode enabled Lighting Quality mode disabled
The chart is blue (high quality). Note the shadow under the awning.
Let's look at one last example of how Enlighten lights the level. In the World Outliner, double-click the actor Buildings_Wall_Tiling9 to focus on it.
When viewing the wall in Lighting only mode, you might notice a seam between the wall actors. This is caused by the actors using different Enlighten quality levels. This shouldn't be a problem, since in Lit mode, the seam isn't noticeable.
Lighting only Lit + Lighting Quality Lit + Defaults
Note visible seam in the wall. The seam is caused by the different lighting quality levels. When the level is lit, the seam isn't noticeable.
In the World Outliner, select the DirectionalLight actor.
In the Details tab, under Transform, set the XYZ values to X:0, Y:-50, Z:0.

This rotates the DirectionalLight so that the direct light reaches the wall in the alley. Notice the reflected light has a red tint.
Lighting Only Unlit + Enlighten Quality
As the lower levels of the building use High quality, they capture light reflected from the DirectionalLight more accurately. The effect is still visible on the higher levels that use Medium quality, but the result is less accurate due to the larger lightmap pixel size.
