Ground Environment Prepar3D World Edition

GEP3D takes full advantage of the advancements made with Prepar3D with respect to lighting and cloud shadows. This version adds a major content update as well as full Prepar3D v4 support. GEP3D can be used for any version of Prepar3D version 1 through version 5. GEP3D comes with Ultimate Terrain Prepar3D support for all current and future supported Ultimate Terrain Prepar3D region products. If you are not looking for support for professional pilot training, military, FAA, academy training, or, affiliated with a corporation and require that support, the Professional and Enterprise license editions are not required.

Performance and Sight Seeing in One Package

You can now experience a Flight1 award winning scenery product that changes the entire Prepar3D simulation ground texture and autogen world from pole to pole in one install. Ground Environment Prepar3D (or GEP3D for short) greatly improves the Prepar3D simulation world with detailed texture sets which include a complete set of matching night lighting maps. Autogen has been meticulously placed and done so with reasonable virtual address space (VAS) consumption and overhead in mind. A secure backup is established by the product for easy and quick restore at any time.

From Kabul to Kathmandu, from Cape Town to Anchorage Ground Environment strives to make the world look like the world and not sacrifice one part of it for another.

The product is available in two versions and follows the Lockheed Martin EULA for each.

GEP3D is designed to run though a graphic interface which has been preprogrammed to monitor user input and correct for any errors instantly.

Activation/Installation, setup and use of the product is very simple and automated for the most part. There is no setup or change needed once the files are activated in Prepar3D and the interface can be closed until a change or update is applied.

Ground Environment and Ultimate Terrain Landclass/Scenery Products

Ground Environment is a development partner with Scenery Solutions and their Ultimate Terrain series. All Ultimate Terrain products have been pre-tested and verified for use with GEP3D. As the Ultimate Terrain developers release and update their products for Prepar3D the Ground Environment team will be there to maintain continuity between the product lines for seamless blending between the two products. The combination of the latest Ground Environment and Ultimate Terrain products produces one of the highest volume autogen renders with the least virtual address space consumption, something that is critical for the serious simulation user with current render engine limitations.

Ground Environment and 3rd Party Landclass and Vegetation Products

GEP3D supports all the major and minor freeware and payware landclass products on the market that do not alter landclass texture calls and follow the SDK for Prepar3D.
