LODActors render incorrectly

REGRESSION: Yes, I could not reproduce in 4.14.

LOD Actors are not rendering correctly. All the textures are black, and don't appear to be using the materials on the meshes in the cluster.

1. Open QAGame.
2. Open the level TM-HLOD.
3. In the World Settings, enable HLOD.
4. Click on Window ? HLOD Outliner.
5. Click the + icon for Hierarchcical LODSetup.
6. Click Generate Clusters.
7. Click Generate Proxy Meshes.
8. Drag the Forced Viewing Level slider all the way to the right.

RESULT:

The teapots and floor are black.

EXPECTED:

Teapots to be red and floor to be default.
