Hi! You are correct! However, to clarify the visibility issue mentioned by the OP is in fact a limitation of SkyMaxx Pro. I believe this comes from the fact that correct visibility in X-Plane is done with the dreaded white wall of fog. This is the same wall that SkyMaxx Pro disables to prevent the abrupt white out in clouds. This is a huge improvement when transitioning through clouds however you loose the ability to actually simulate very low visibility approaches.
