[RELEASED] for UE4: Complete Sky and Weather System

Hello to all. I’m trying to get Ocean Blueprint http://.unrealengine.com/community/work-in-progress/17331-community-project-wip-weather-ocean-water-shader to share with 4.20. I enter the ocean in an empty scene and you see, when I insert the sky is not seen (black) but it is mirrored on the ocean, when I make the ocean invisible you can see . I tried to insert the Transparency Modifier node on the M_Ocean_Ultra material but the sky remains black.
Does someone work?
Thanks
