LightmassImportanceVolume Casting Shadows


It seems the LightmassImportanceVolume is casting shadows on the landscape.

The shadow falls at the edge of the original landscape, which was approximately the size of the original LMIV.

With World Composition, additional landscapes have been added. The LMIV has been expanded (to the new edges).

Is this behavior expected? Is there a way to disable the LMIV shadows?
