HDRIBackdrop Sky Regenerate

In native Unreal Engine and Unreal Editor for Aximmetry, the HDRIBackdrop plugin does not show the HDRI correctly in some cases in cooked mode.
If you find the HDRI is only showing the ground and the sky is replaced with a default grid texture. You need to add the above blueprint nodes to your Level Blueprint.
NOTE: Recapture Sky is a relatively expensive process; therefore, you should not run it in every frame just as a separate process that only runs when necessary.
NOTE: This issue usually occurs when using Envirdome in the HDRIBackdrop/Geometry/Static Mesh property.
