  • - Separate lighting adjustments for aircraft externally and internally - now you can adjust the lights for the VC separately to the external model. There are 2 separate tweaks for lighting adjustments for aircraft externally and internally
  • - Tweaks "Reduce cloud brightness at dawn/dusk/night" and "Reduce top layer cirrus clouds brightness at dawn/dusk/night" now have adjustable parameters
  • - New tweak "Turn off clouds directional lighting" allows you get old-style Prepar3D v3 lighting for clouds
  • - New tweak "HDR bloom multiplier" allows a separate adjustment of HDR bloom during the 24hr day cycle (day/dusk/twilight)
  • - Minor bugfixes

All presets from PTA 2.5X are compatible

The old values of the "Aircraft lighting & saturation" tweak now appear in the "Aircraft lighting & saturation" tweak. If you used only the VC adjustments, please use the new tweak, "Aircraft VC lighting & saturation".

How to install:

PTA is a standalone, portable application. Unzip the contents of the archive supplied as a download with your purchase to a folder of your choice. Run the .exe and follow the on screen instructions.

Before using PTA, please make sure that have all the original Prepar3D 4 shaders installed into the sim. Tweaked or modified shaders can't be used by PTA and will be ignored (See ERROR messages in log). If this happens, just put the original shaders back into the sim and restart PTA.

On launching PTA, it should automatically detect Prepar3D v4 and locate the installation, shaders & cache directory. It will also create backups of various shaders to the \SHADERS_BACKUP subdirectory in the folder you've put PTA in. Config files used by PTA will backup to the \CONFIG_BACKUP subdirectory.

Important - Please do not delete or modify contents of the subdirectories or you will lose the ability to restore backups.

NOTE - PTA v2.50 will work with PTA v2.00-v2.11 installed at the same time on the same PC however they require to be their own SEPARATE directory.
