Remarks

Whether to light this component and any attachments as a group. This only has effect on the root component of an attachment tree. When enabled, attached component shadowing settings like bCastInsetShadow, bCastVolumetricTranslucentShadow, etc, will be ignored. This is useful for improving performance when multiple movable components are attached together.
