Skybox planets show concentric glow rings and cause halo outlines on objects

In Racing on Volant Station, planets in the skybox render with an unnatural concentric glow radiating from the planet center to the edges. The same lighting artifact appears to interact with scene objects, producing halo/outline highlights on character silhouettes and on edges of rocks and other station scenery elements.

1. Launch the game on Live Version: cl82-ue581-siege-lowbie-fix-20260916-r1-eacprotected-resigned.
2. Enter RACING mode on the VOLANT STATION map.
3. Look at the planets in the skybox and observe the glow pattern.
4. Observe character outlines and edges of rocks/scenery for halo-like lighting interaction.

Planets in the skybox should render with stable, realistic lighting without concentric glow rings, and skybox lighting should not create halo/outline artifacts on characters or environment edges.

There is a lighting issue related to the planets in the skybox; they display a concentric glow extending from the center of the planet toward the edges.

Light interactions are occurring with other objects, such as the outlines of characters or the edges of rocks and other elements of the station's scenery.
