I have no indirect lighting

Hi guys.

First time poster here, so be gentle with me!

I’ve only been using UE4 for about a week, so I’m a total amateur, but I’ve done hours of searching, testing, and reverse engineering other people’s scenes to try and figure out what I’m doing wrong here, but I’m no closer to an answer.

As far as I can figure out, the problem seems to be that I’m getting no indirect lighting from directional lights (or seemingly any other lights). The indirect lighting slider seems to do absolutely nothing to my interiors.

To illustrate as best I can, I loaded up the beautiful Lightroom from the Unreal marketplace, made a small windowed room next to it, and built lighting. As you can see, the light behaves incredibly differently.

This is what happens in every project I’ve started. I can make everything brighter with exposure and a few other little tricks people have shared, but nothing that gives that wonderful natural light effect seen here.

For these pictures, every element and setting has been untouched, the only change is the room I made from geometry brushes. The single directional light is the only lightsource (as far as this newbie can tell). If you need any more information, don’t hesitate to ask.

No doubt I’m making some stupid little mistake, and I only hope somebody can point it out so I can carry on learning this fantastic engine.

Many thanks.
