Hi, I would try and buy skymaxxpro. Actually I try and install different freeware , the latest is product of Sabach who modify also reflections, moon etc If I understand, if I install skymaxxpro , the "default" clouds etc will be Sabach and for the next update I have the choice to overwrite (for obtain the original defaut xplane) If I don't overwrite, I can keep Clouds of Sabach like "defaut clouds in Skymaxxpro. May be it's better to re-update xplane to obtain a "fresh" install before try and install skymaxxpro but I am not sure is the best way in my case. Could you confirm? Thanks
