Lockheed Martin

Lockheed Martin has released Prepar3D v5.1 Hotfix 1. The new hotfix addresses many issues such as cloud issues with Enhanced Atmospherics, rendering issues and other weather-related issues.

Looking at the changelog of client fixes and improvements, Enhanced Atmospherics (EA) seems to have a large number of changes based on feedback. Issues with cloud aliasing have been reduced, along with flashing clouds, and shadow flashing. Furthermore, there has been additional configuration options to how clouds are generated. Other fixes include changes to fog/haze implementation, ambient lighting and also how some forms of vegetation is drawn in the simulator.

You can download the newly released hotfix for Prepar3D v5.1 from the Prepar3D website. A full download of Prepar3D v5.1 will need to be downloaded and the hotfix will be included. (Update: You can also download the client and scenery installers to grab the hotfix. The majority of the changes can be found in the client installer).

As usual, various third-party add-ons may need an update to be compatible with the new hotfix. For reference, the new Prepar3D version number is 5.1.12.26829.

When Lockheed Martin announced that Prepar3D v5 would be coming soon, we began in earnest our plan on how we could support the community with moving to Prepar3D v5. To help, we have put together what we’re calling the Prepar3D v5 Upgrade Hub.

This hub has been designed with the community in mind to help provide information in a single place to help you move to the new version of Prepar3D. On it, we have the latest Prepar3D v5 news, an FAQ, various videos (from us and others), and a series of compatibility lists.

The compatibility lists are a live and updated table of products from Prepar3D v4 with compatibility for Prepar3D v5. We have sourced the information from various places (including our initial Developer Statement article) and we are now working with developers to keep it as updated as possible. To help, we have broken it down into the following lists:

• Aircraft
• Scenery (Non-Airports)
• Airports
• Utilities

We’re aware that there are still many products missing, but we are adding them all the time. That said, we are still looking for community support. So if you see something which we’ve missed, please use the submission form to let us know. We’ll review it as often as we can and update the lists accordingly.

For now, let us know what you think of the Upgrade Hub, what else we can add to help you and any other feedback.

You can access the Upgrade Hub here.

Here’s a direct link to our compatibility table.
