In direct sunlight, the slightly yellow light of the sun pretty much overpowers the bluish color (or colour, if you prefer) of the sky. Step into deep shade, and you just get the bluish cast of the sky without the direct sunlight, hence the need to use the 'shade' white balance setting on your camera, to filter the bluishness (is that a word?) out. If you don't include a sun (or strong distant light) in your scene, what you are creating is a shade lighting situation, which realistically should have a bluish cast. Maybe the thing to ask Eovia for is the equivalent of tungsten/fluorescent/daylight/shade camera filter settings?
