You should see NO clouds outside your windscreen, if you see clouds increase the avg luminance value until you no longer can see clouds. This is date and time in which there is no moon. Click map, set the aircraft altitude to 35000 ft, and load the thunderstorm weather theme. Next Fire up P3D, set the date to at night, and load the sim using your favorite aircraft someplace in the northeast usa. Remove the slashes and change the 0.85f to 1.20f for now. This controls the rate and which your eyes adjust to changing light conditions.ģ: Find the entry for //avgLuminance *= 0.85f, this is what we will be using to darken the nighttime. Find static const float TimeDelta = , change this to 4.5f.
Find static const float BloomBlurSigma = , change this to 1.3f. You don't want this too low or moonlit objects will see a bloom effect. I set mine to 4.10f, others that like less bloom will want to set this higher, perhaps around 5.00 or more. This top parameter determines the level of brightness that bloom will be applied. Find the entry static const float BloomThreshold = close to the top.
This is the only mod to this file.Ģ: Open HDR.hlsl, the remainder of the tweaks will apply to this file. The tweaks we are going to apply tend to wash out the colors slightly and this should restore them back to what you are used to. I am going to do my best to outline the order of these modifications that will yield the most efficient process.ġ: Open GPUTerrain.fx and find this line : BaseColor *= lerp(. You may get perfect settings using my values, or you may have to modify them quite a bit.Įvery single setting we are going to discuss is related to the others so it is important to understand the effect they have on each other.
AppData/Local/Lockheed Martin/Prepar3D v2īefore we start tweaking it is important to understand that this involves a lot of trial and error and the settings used will depend heavily on your monitor calibration/size/resolution, sky textures, clouds, and sun textures. Prepar3D v2 Main Directory/ShadersHLSL/PostProcessĪfter modifying any of these shader files be sure to delete your shader folder located in. Prepar3D v2 Main Directory/ShadersHLSL ,the next is HDR.hlsl located in The two files we will be modifying will be: GPUTerrain.fx located in. If you are using an HDTV I find its best to disable any of the "adaptive contrast" or "color enhancer" settings as well.
This can be tough to get 100% perfect without professional equipment, but link to the site below has helped me and should get you close enough.
If you expect to get the same predictable results that I have been getting you need to calibrate your monitor as accurately as possible. You can see my results here on this thread: I want to give credit to Rob Ainscough and others who have provided insight on modifying the hdr file, as these tweaks build off of their findings. You should be able to make the effects as dramatic as you want without having to use sweetfx or enb type mods. If set up correctly all of this plays nicely with cloud shadows which will still remain dark, it is now a truly realistic experience to break out from under a dark gloomy overcast. The purpose of these tweaks is to increase the range of the HDR in P3D allowing for the kind of dark nights where you wont be able to see a wing or cloud unless there is a light shining on it, while also getting a brighter daytime than default that will showcase the true power of the sun.
I was not sure if I should post this here or in "Tips and Tricks" but if the Mod's feel this post belongs there instead feel free to move it. Hey guys, in this post I will be explaining some simple tweaks that I have been testing on my system that will increase the "R" in HDR.
