AS16_APP_ICON_P3D                              ASCA_APP_ICON31

Service Pack 1 for AS16 and ASCA has been officially released after several months of testing, both internal and public via our OPEN BETA testing cycle. Thanks to everyone who participated and provided great feedback to help make SP1 as solid and fine-tuned as possible!

SP1 for AS16 incorporates significant enhancements, adjustments, fixes and tweaks to further increase realism, immersion and functionality. Highlights include new P3D visibility improvements, cloud motion effect improvements, improved restricted visibility depiction, new jet-stream and wind-layer shear turbulence influence effects, interpolation improvements, generation depiction improvements, additional API functionality, P3D v3.4.18 support and much more.

SP1 for ASCA brings brand new softer cloud textures, a new cirrus set, revamped original cloud and sky textures, new natural sky color sets, new integration and API capability, improved overall resolution, improved overcast depiction, new geographic wx-influence profiles, and several new UI features including new option, plus more!

Both SP1 upgrades are available absolutely free of charge to all AS16 and/or ASCA users. Visit our downloads page to download right now!

AS16 (Active Sky 2016) is HiFi’s latest full-featured reality-based weather and environment engine. ASCA (Active Sky Cloud Art) is a dynamic sky and environment graphics package with breakthrough features including real-time cloud texture dynamics and brand new cloud structures, completely transforming your skies. Both are designed to run fully integrated or stand-alone, and are fully compatible with all other add-ons including weather engines and graphics enhancements.

A free fully-functional 7-day trial of AS16 SP1 is available to everyone, even if you’ve tried AS16 before. All trials have been reset.



Visibility Improvements, Effects Improvements, New API Features and More!

Redesigned P3D visibility depiction was overall a great improvement to debut in AS16, but many users had different needs and expectations, and asked us for enhancements in several key areas including elimination of excessive haze at the horizon, elimination of occasional sudden visibility shifts around 10,000ft, and better restricted visibility depiction, both surface and aloft, without harsh lines in certain scenarios. We’ve reworked the visibility depiction again, and significantly improve these areas (and several others) with SP1.  Cloud motion effect detection/synchronization and general speed sensation and particle effect placement was another area our users asked us to work on, and we have spent considerable time improving this for SP1.

Beyond the visibility and effects improvements, there are also new user options, improved turbulence effects, jet-stream and boundary-layer turbulence effects, general depiction and interpolation improvements, and hundreds of minor fixes and adjustments in effort to make AS16 even better.

Finally, many new API functions and capabilities have been added, enabling all kinds of developers to tightly integrate with Active Sky technology in all aspects including getting and setting weather, controlling weather modes and more.



  New Cloud Textures, Cirrus Clouds, and Sky Colors

You asked, we listened!  Newly improved overcast models, 6 new soft-style cloud texture sets, 7 new hyper-natural sky color sets with improved high-altitude saturation, vibrance and brightness graduation, a new cirrus cloud set, reworked and improved original cloud sets and sky color textures, remapping of all associations and definitions, new UI-based weather influenced configuration, and a new Art Tools API are just a few things that have been added in ASCA SP1.  Improved overall resolution, better dynamics, new geographic selection influence, and more user options are also included.

You can now create your own custom content and make it ASCA and AS16 compatible with full dynamics capability, with just a few clicks of the mouse – enjoying full weather and geographic profile selection influence.  Currently, Sky Color textures are supported, and more categories are planned to be added soon.

We hope you’ll agree that ASCA SP1 is a major step forward in the ongoing effort to provide the most realistic and dynamic weather visual experience possible.





 Adjustable Full Dynamics Overcast resolution setting

You can now customize overcast to the resolution of your choosing.


Art Tools API

One of our newest additions to features is our Art Tools API which allows users to create and share their own ASCA/AS16 content – Currently enabled for Sky Textures only

 WX Influence Configuration!

Get only the looks you want! The new Wx Influence Configuration utility (available via the Settings Screen) allows user to adjust Wx selection profiles and geographic profiles for all content




While ASCA and AS16 work great together, they are also fully compatible (either alone or together) with any other graphics add-on and weather add-on. You have full flexibility to mix and match any aspect and selectable feature set within these add-ons.

– Implemented better handling of stalled/error of ASCA installation during theme reload, so that AS16 weather will not stall (and an error message will be shown indicating ASCA error, while weather depiction continues)
– Updated documentation, Performance Considerations chapter, to mention CLOUD_SHADOW_TEXTURE_SIZE setting recommendation of 256 (vs 512) to improve performance
– Added new Warnings option for cloud density slider setting warning
– Attempted wake encounter filtering when flying helicopters, using ATC aircraft ID against known helicopter ICAO types (requires aircraft to use proper ICAO types, and not all add-on helicopters do)

 Visibility Improvements for P3D:

– Further redesign and improvement in visibility depiction and configuration
