Lighting Quick Start Guide - reflections not working as expected

While working through the lighting quick start guide, specifically around creating the Box Reflection Capture object, I’m not getting the same result as in the tutorial.

From the tutorial: https://docs.unrealengine.com/Images/Engine/Rendering/LightingAndShadows/QuickStart/boxPlaced1.webp

My screenshot is attached.

What I can’t understand is why there is a line indicating the boundary of the reflection capture (which presumably decreases the indirect light bounces beyond the boundaries of the box reflection capture object), but not in my scene. In fact, the result seems pretty much the same whether or not I have the box reflection capture object in the scene at all.

I’m on UE 4.25.1 for reference, which might be different to what is used in the tutorials.

Hey ohookins! Thanks for reaching out to us. I’ve passed along your question and am currently waiting to hear back from a colleague. Once I have a response I’ll let you know.
