Lumen reflections
Lumen reflections can now be used in combination with Enlighten indirect lighting. This improves the accuracy of reflections for materials with low roughness.
The images below show spheres with roughness 0.1, 0.2 and 0.3 in a location lit indirectly. The image on the left shows Lumen reflections OFF, while the image on the right shows Lumen reflections ON.

When using World Partition it is recommended to use the default Runtime Hash Class of WorldPartitionRuntimeHashSet to avoid problems with spatially loaded actors.
Fixed bugs
- Fixed an intermittent GeoPrecomp2 process hang during the precompute on some machines.
- Fixed rare black probe lighting artifacts that could occur close to thin walls that separate disconnected areas.
- Fixed failure to fall back to sky lighting in game mode when both persistent level and first loaded sub level have no Enlighten data.
- Fixed failure to fall back to sky lighting in game mode for actors spawned by a blueprint.
- Fixed failure to fall back to sky lighting in game mode when Enlighten Bounce Distance is non-zero.
When the density of Enlighten probes is too high, the precompute now reports the correct location of the highest density.
- Fixed a crash after reimporting a static mesh asset that is open in the Static Mesh editor with Enlighten Charts view enabled.
- Fixed invalid lighting for foliage with detail lighting mode on platforms with manual vertex fetch disabled.
