Description

In 4.27, ray traced point lights can leak through thin meshes.

This bug does not exist in Unreal Engine 5, due to many of the potential rendering areas being fundamentally changed.

Steps to Reproduce

1. Download the Licensee's test project and open
https://udn.unrealengine.com/s/contentdocument/069QP00000Lb4esYAB
2. Observe the light "PointLight" leaking through the top of the cube "Cube"
3. Delete everything else but those two actors
4. Observe the light leaking remains
5. Disable ray tracing and restart the project
6. Observe the light is no longer leaking through the cube
