A complete dynamic environment for games and simulation. Available for all major console platforms, Simul Weather v.2: trueSKY is the most advanced and reliable sky system available.

trueSKY™ is a C++ library which generates weather system data and updates it in real time. trueSKY™ creates volumetric cloud data, and provides realtime access to that data via a lightweight API. The cloud system generates pure volumetric data, it is cross-platform and renderer-independent. The sample applications that come with the SDK show how realtime clouds can be rendered using the generated cloud data, in various graphics API’s.

Reduce development cost

Real-looking skies are universal – so why reinvent the wheel? Simul Weather™ has been used by numerous AAA developers and Fortune 500 companies, and has been shown to deliver speed, visual quality and flexibility. Instead of spending vital man-months on recreating the sky, you can have perfect skies, instantly, and concentrate your resources where they’re most needed.

Gain performance

trueSKY can produce significant performance gains over bespoke sky systems. We’ve optimized our rendercode for speed and low memory usage, using patent-pending Simul technology.

Time of Day

Why choose between having changing time-of-day and spectacular skies? With trueSKY™, you get both. New gameplay innovations become possible when you have complete control over time, weather and atmosphere.

Complete Control

Do your artists struggle with bespoke time-of-day and weather tools? Simul Sky Sequencer™ offers a AAA-quality graphical interface. Copy, paste, undo mistakes, and see the results in real time.

Reduce Development Time

How long does it take for your game to start looking triple-A? You can kickstart the visual quality of your product with trueSKY. Just put it in, and your skies are sorted. The rest is up to you.
