Since yesterday Prepar3D v4.5 is available for download. As usual, existing customers will find the new version in their customer account. The update for the popular flight simulator by Lockheed Martin brings among other things an improved night lighting with itself. In addition, the developers promise greatly reduced loading times for complex scenarios. Further changes will enhance color and lighting when using Physically Based Rendering (PBR). Prepar3D v4.5 also supports PBR effects for oxyfuel vegetation.

Physically Based Rendering introduced Lockheed Martin for the first time in December 2018 with Prepar3D v4.4 (We reported). Also this time a complete new installation of the flight simulator is not necessary. Instead, it is sufficient to reinstall the client. How exactly this works is explained in our tutorial.
Popular programs like the GTN Complete Edition of Flight1 or Active Sky for Prepar3D v4 also require an update to be compatible with Prepar3D v4.5. Usually these updates should be available within a short time.
