New P3D add-on folder specification/design, with everything installed outside of the P3D folders – Includes ASCA support (with SP3 Update).

New P3D v5.1 HF1+ Enhanced EA integration system design for improved synthesis, depiction, interpolation, flight plan awareness, grid effect reduction, cloud scene smoothing, visibility smoothing, visibility accuracy improvements and more.

ASP3D evolves realism-based weather simulation, building upon the ground-breaking and proven features of ActiveSky while integrating with the latest simulator platform from Lockheed Martin Prepar3D v5.1. If you are upgrading, please use this upgrade product page.ĪSP3D is the latest addition to the ActiveSky weather simulation engine line. You can use any graphics add-on(s) with ASP45, but dynamic texture reloads require the ASP4+ASCA combination.Use this page only if you are completely new to this product and not upgrading from a previous HiFi Technologies product.

ASCA includes cloud textures, sky textures, and 3D cloud models to transform your skies, while also incorporated Real-Time Dynamic Cloud and Sky Textures! This enables realistic weather-influenced texture variation that reloads throughout your flight without needing to shut down and restart your simulator. In-Cloud Motion Effects, Weather Scenarios System, Airborne Weather Radar, P3D Visibility Smoothing and Volumetric Fog Integration, Navigraph Data Integration, Map-based Custom Weather Editing System, Universal Web Companion App, Mapping System and a High-Latitude Cloud Squeeze Fix are just a few of the advanced features included in the core Active Sky platform.ĪSP4 also incorporates full integration with Active Sky Cloud Art ( ASCA), our graphics add-on for both FSX and P3D.
