xAmbiance Pro developer, HST Simulations, has recently shared via the X-Plane.org Forums a couple of screenshots directly from X-Plane 11 showcasing the upcoming volumetric clouds feature. When released, the addon will be compatible only with X-Plane 11.50 stable.
Although it was mentioned, that the addon is getting close to becoming truly complete, it was later made clear, that the screenshots are still not representing the final product. A new development update is scheduled to be released soon.
At the end of the post, there was a simple sentence included saying: “We will introduce volumetric clouds in 2020”. xAmbiance Pro will not only feature volumetric clouds but should we overall next-generation plugin.
