Hello All,

Below is a hotfix to bring 2.5.12942.0 & 2.5.12943.0 to 2.5.12944.0.

Professional Plus:

The hotfix addresses the following issues only:

  • Incorrectly shadowed 3D waves with Bathymetry enabled

  • Sun glare with HDR enabled

  • SimDirector GamePad missing entry crash

  • Dull night lights in virtual cockpit and panels

Extract the appropriate zip file and copy the contained files on top of your default installation. You should accept all prompts to overwrite files (Yes or Yes to All).

The full Prepar3D download links will be updated in the near future to include this hotfix, but you are encouraged to use this hotfix patch whenever possible.

Please be aware, if any third party software modified any of the dlls included in the hotfix, you will need to reinstall their content/add-on. Please check with the specific add-on provider to see if this is necessary. Additionally, when using this hotfix, any Prepar3D repair or reinstallation will need the hotfix reapplied.

Thanks for being a part of the community and enjoy,
Prepar3D® Engineering Project Manager

Hi Adam,

So we don't need to install the previous hotfix if we haven't already? Is it part of this hotfix?

Many thanks

It is interesting that AI shadows are now appearing on photo-scenery with tessellation on :)

Good Afternoon,

Thanks a bunch for getting these patches out so swiftly. One quick question though. When we perform a clean install of Prepar3d v2.5, do we apply each hotfix or only the latest hotfix?
