in fsx REX weather update disapeared from selection options in Resolved Issues Posted September 16, 2018 Hi, Please see my previous post: 23 hours ago, REX Support said: Hi there, Never touch the weather themes area when using REX! If all is working correctly, it should automatically populate as User-defined when REX injects weather, but it requires no input on your part. The weather theme you see is the last injected weather and will not properly update if you select it. You should leave it be; do not select the REX theme and allow Sky Force to inject automatically. Weather smoothing will be coming with Weather Force, which will fix the weather transitioning issue. It will come as a free update for all Sky Force customers.
