Anyways, please see below for a complete update changelog.


  • Enhancing Clouds colors. especially blue color. some users reported as a violet another purple.
  • Enhance the shadow of clouds. the jagged shadow while looking down removed and adjusted automatically during moving view upward to prevent the shadow lines at the horizon. (you may found some moving jagged shadows while transferring the view down and up or horizontal view, and that due to a limitation on x-plane 11.30+ new shaders system which is taking ready for “Vulkan” which we never touched but the shaders affect the plugin somehow for sure) *remember UWXP does not control any shaders*.
  • Enhance Auto Night Haze, some cities didn’t have any haze and the sky looks dark, now there is a little haze showing.
  • Decrease the brightness aircraft in the external view at night. (can’t remove the full brightness we will lose the night haze then)
  • Airport lights turned on under overcast and turned off above overcast during day time, now the lights are off during day time even with overcast condition with the ability to turn it on again with the new checkmark “Overcast Airpot Lights”
  • Enhance the Sunset Sun Texture for all Clean, Mount, Hazy conditions, for all skies textures.
  • Changing the whole simulation lights which being turning on before sunset, now it has been delayed a little.
  • Changing UWXP Main Set button values and some of the selected settings.
  • Increase the value of the Moon Glow slider. (the moon glow affected by the Auto night haze system, so we’ve increased the value of it.) sometimes you can’t see the glow due to the city size, then you need to ignore it or just turn off the auto night haze.
  • Enhancing the slider of Amount of clouds, now the clouds have a lower value at 0%.
  • Enhancing the amount of Amount of in Clouds Puffs, now the Flying through clouds puffs have a lower value at 0% (for the users who struggle with FPS even with FPS fix)

  • Including Linux system, navigation screens turned off Fixed.
  • Including Windows 7, automatic system not working Fixed.
  • Including FPS++ Fix as a separate file. in case the user wants to use it. (find it inside the package in the “UltraWeatherXP” plugin folder )
