When using a point light far from the world origin the light will have banding. The shadow bias and filter sharpen can help but they are not as consistent as settings near the world origin. The only affects Movable point lights. Stationary with movable actors do not exhibit the same banding.

As a note, when using World Composition, the issue is still present even though the world origin should be shifting with the camera position as well.

Steps to Reproduce

1. Create a Default Level
2. Move the Floor mesh to any distance on the X or Y beyond 80k.
3. Add a Point Light and set it to Movable.

Results: Light banding at large distances from the world origin.
