The Powerful CH-53E Super Stallion – Download v4.2 today!

Prepar3D v4.2 is available now!

Prepar3D v4.2 continues to improve on the groundbreaking Prepar3D v4 simulation platform. The new v4.2 release welcomes three new user controllable helicopters, new rendering techniques for improved virtual reality (VR) performance, countless legacy bug fixes, and even a couple new exciting experimental features to give users a feel of where the platform is heading!

This is the first release to feature new helicopter capabilities, including scenario controllable artificial intelligence (AI) and autopilot functionality. Additionally, many developer requests were addressed, and we look forward to the Prepar3D ecosystem continuing to create high-end content that pushes simulation boundaries to new limits.

For developers, we have introduced the ability to add autogen grass on airport backgrounds, added interfaces to create custom voice commands, and refined our support for complex vehicle models. Multiple Scaleform panel samples are also included better showcasing some of the newer advanced panel features that available.

All of these enhancements are available now in Prepar3D v4.2!

The Prepar3D v4.2 update is available now and can be downloaded from the Downloads page. If you currently own a valid Prepar3D v4 license there is no charge to update to Prepar3D v4.2. To purchase Prepar3D v4, please visit our online Store.

Prepar3D offers separate updates for the Client, Content, and Scenery. This will make updating faster and easier than ever before. Please be sure to read the Prepar3D v4 Download and Installation Instructions for more details on how to quickly update to the v4.2 release. Please refer to the What’s New below to see what each installer contains. Most users will only want to use the Client installer to update.

You can find a full list of What’s New below.


Release Notes

The following list of updates has been categorized based on the installer required. The Client installer is required for Prepar3D v4.2, however the Content, Scenery, and SDK installers are optional. You must first have Prepar3D v4 installed to utilize the Client only installer. To install the Prepar3D v4.2 Client, you must first uninstall the previous Prepar3D v4.0/v4.1 Client through Programs and Features in Windows Control Panel.

The Prepar3D v4.2 Client update will require you to reactivate your product – with an internet connection it will be automatic.

More than 30 flight simulation developers—including Prepar3D—have made an initial commitment to attending FlightSimExpo, North America’s community-driven flight simulation conference. The event takes place at Flamingo Las Vegas Resort on June 9-10, 2018.

The event consists of both a tradeshow floor and a conference room. FlightSimExpo 2018 will feature a variety of interactive exhibits, and a host of educational and informative seminars from professionals across the aviation and flight simulation industries. In addition, there will be social events after conference hours for networking and connecting with other simulation enthusiasts, aviation professionals, and developers from across the simulation industry.

Lockheed Martin will be in attendance to represent Prepar3D, a visual simulation platform that allows users to create training scenarios across aviation, maritime, and ground domains. Prepar3D has become the go-to platform for serious flight simmers, and developers creating top-tier add-on products for at-home simulation. Prepar3D will be represented by Adam Breed, Prepar3D’s engineering project manager, and Rob McCarthy, Prepar3D’s commercial development lead.

FlightSimExpo truly community-driven: the venue, host city, and event activities have all been determined by feedback from the community and developers. FlightSimExpo is an all-ages event, in a host city where there are great and inexpensive activities for families, individuals, and groups all nearby. The conference is working on partnering with local attractions, and bringing in top-tier speakers.

Early bird registration is available until February 1 for just $50. Discounted event rates for the hotel are approximately $135/night including all taxes and fees, over a 3-night stay. Attendees can register for the event online, and book rooms at www.flightsimexpo.com/hotel.

Visit www.flightsimexpo.com for more information about the event, venue, and pricing. Interested attendees are also encouraged to follow FSExpo on Twitter (@FlightSimExpo) and like the conference on Facebook (www.facebook.com/FlightSimExpo) for updates.
