Cities come to life with more detailed night lighting in v4.5

The latest update to Prepar3D is now available! Prepar3D v4.5 continues to build upon the solid foundation and advancements made to the platform by bringing new features, improvements, and fixes across the board.

Terrain night lighting has been overhauled adding greater visual detail and clarity. Highways illuminate through cityscapes like never before and sprawling urban environments come to life extending to the horizon with higher resolution night textures.

Major optimizations have been made to model loading vastly reducing load times for complex scenery add-ons. Additional enhancements were made across the entire platform ranging from smoother multiplayer animations, greater Virtual Reality (VR) performance, to improved Physically Based Rendering (PBR) lighting and color balance.

Immersive cutting-edge training across the globe in v4.5

Expanded developer features including support for PBR autogenerated vegetation, greater effects customization, and various interface updates and new services further expand Prepar3D’s open development architecture enabling richer and more customizable content.

New features added to the Professional Plus product include Distributed Interactive Simulation (DIS) auto-connection, DIS engagement lines, and Common Image Generator Interface (CIGI) collision detection expand Prepar3D’s interoperability between professional simulation platforms. Additionally, multiple improvements to SimOperator including full sound support, a real-time progress log, and object visual ribbons, helps bring interactive scenarios to life while enhancing operator situational awareness.

Take your training to new heights with Prepar3D v4.5!

For those wishing to use the Oculus Rift, please see this forum posting for important information.

For the complete details on the release, please see the What’s New below.

The following list of updates has been categorized based on the installer required. The Client installer is required for Prepar3D v4.5, however the Content, Scenery, and SDK installers are optional. You must first have Prepar3D v4 installed to utilize the Client only installer.

Take to the skies like never before with Prepar3D v4.4! Groundbreaking features and improvements make this the largest and most comprehensive Prepar3D point release yet. Prepar3D v4.4 not only adds extensive new features to the platform, but also includes numerous user and developer requests including multiple fixes identified by the community and further expansion of Prepar3D’s open development architecture.

Physically based rendering brings next level realism in v4.4

A focal point of this release is the core rendering engine has been updated to fully support Physically Based Rendering (PBR) laying the groundwork for next-level realism and unparalleled graphical fidelity in a full earth simulator. New content created using new PBR capabilities will allow all different types of materials, including metals, plastics, concrete, and glass, to be rendered and lit based on their unique physical properties.

Photoreal scenery has never looked better in Prepar3D v4 with new high-resolution texture support offering up to 16 times the detail in previous versions.

In addition, scenery objects can now be drawn at further distances, most add-ons will no longer require a restart when enabling or disabling them inside the application, moon lighting and cloud appearances at night has been overhauled, and to showcase the new PBR pipeline, the native F-16 aircraft materials have been updated to PBR. The release also features an AC11 Commander provided by Carenado and an update making the Indago Unmanned Arial Systems (UAS) a user controllable vehicle. Both vehicles are great examples of how Prepar3D can be used for diverse training and simulation goals – from training classic single engine propeller planes to simulating advanced unmanned systems.

F-16 night takeoff with dynamic aircraft lights and afterburner

Prepar3D Engineering Project Manager Adam Breed commented on the v4.4 release saying, “this is the most significant point update we have made in Prepar3D’s nine year history. We have pushed the platform forward in a major way with this release.” Prepar3D Commercial Lead Rob McCarthy added, “we are looking forward to seeing what the ecosystem creates with the new PBR system. The PBR prototypes we have seen have blown us away and we can’t wait until our end users get their hands on the finished product.”

Experience next generation training now with Prepar3D v4.4!

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.
