I just found this post at the REX forums that suggests they are considering a product for X-Plane 11. While I have enjoyed xEnviro, and consider it a huge upgrade to X-Plane’s default weather engine, I’ve found the METAR data spotty and it is still (and in fairness to those devs, who have been great) very much a platform in development. In P3D I was a huge fan of REX Direct’s work, and would love to see them produce a cloud or weather product for X-Plane.
REX guys … if you’re reading this: name the price and the entire XP world will follow. And if you’d like a beta tester, let me know.
