Active Sky for P3Dv4 Open Beta Now Available

Img 5931f33d5b8f8

As promised, HiFi Simulations have released the open beta for their Active Sky series for Prepar3D V4. Known as ASP4, it’s been in testing via a private testing team for some time, but now anyone who owns a AS16 P3D license can now participate. You just need to use the same license key to install and use ASP4. If you don’t own one, then we highly recommend buying it!

As this is still a beta, there are some known issues and the team request you don’t report them numerous times.  These known issues are:

  • Real-Time Sky texture dynamics are disabled.  We expect to enable Sky Texture dynamics within the next couple builds.  While dynamics are disable, ASCA sky textures can only be changed by Activating via ASCA and then restarting the simulator.
  • Navigraph data updater has not been updated yet with ASP4 definitions.  We expect a new updater from Navigraph to be available soon which includes ASP4.

As the beta continues, more builds will improve the experience. The team asks that you head over forums to report any bugs to them to help ensure the transition is nice and smooth. to the and the full “official” release will hopefully be in the next couple of weeks.

As ASP4 is a seperate product to AS16, you can run both side by side for use in other simulator environments.

Now how do I download?
