May 5, 201511 yr I've avoided making any Bloom adjustments since I installed P3D V2.5 on my new main sim PC, but decided I'd try out a few changes and post my results: Location ...\Lockheed Martin\Prepar3D v2\ShadersHLSL\PostProcess Backup these two files before proceeding to change them. File ... NVGBloom.hlsl Line 13 static const float BloomMagnitude = 2.0f; Line 15 static const float BlurSigma = 4.0f; File ... HDR.hlsl Line 12 static const float BloomBlurSigma = 2.4; Make sure P3D is NOT running when you make these changes. Also, delete your shaders folder after any file edits BEFORE you start P3D. Shaders folder location (example): C:\Users\YourUserName\AppData\Local\Lockheed Martin\Prepar3D v2\Shaders These are some images (warning large size 3840 x 2160) comparing the difference: Before After Before After Cheers, Rob.
May 5, 201511 yr Hi Rob, Thanks for the info. Already since v2.3 I have 2 HDR batch files : nighttime flying / daytime flying Before flying I choose the appropriate one and it installs the HDR + Bloom settings for that flight. Shortly said : nighttime flying has less effect than daytime flying, like what you suggest above. 5950x3d 5.4-5.7 GHz - Asus ROG 870 Crosshair Apex - GSkill Neo 2x 24 Gb 6000 mhz / cas 26 - MSI RTX 5090 Gaming Trio OC - 1x SSD M2 6000 2TB - 1x SSD M2 2800/1800 1Tb - Corsair 5400 case - Corsair 360 liquid cooling set - 3x 75’ TCL tv. 13600 6 cores @ 5.1 GHz / 8 cores @ 4.0 GHz (hypterthreading on) - Asus ROG Strix Gaming D - GSkill Trident 4x Gb 3200 MHz cas 15 - Asus TUF RTX 4080 16 Gb - 1x SSD M2 2800/1800 2TB - 2x Sata 600 SSD 500 Mb - Corsair D4000 Airflow case - NXT Krajen Z63 AIO liquide cooling - FOV : 200 degrees My flightsim vids : https://www.youtube.com/user/fswidesim/videos?shelf_id=0&sort=dd&view=0
May 5, 201511 yr I am a little confused. Since when is there an NVGBloom.hlsl file as well? Is there a separate bloom effect now?
May 5, 201511 yr can you attach a comparison at 12 AM? The first shot at Split with PMDG 737 was at 12 AM. But here is another 12 AM with RealAir TDuke 2 ... notice the gauges BEFORE AFTER Since when is there an NVGBloom.hlsl file as well? Is there a separate bloom effect now? There are several bloom files that can be adjusted. These adjustments are just about bloom ... they are not about making HDR less dark or making clouds more dark at night. Cheers, Rob.

I've been trying to create two distinct HDR files, each for either day-or night time flying but with modest results. Brynjar Mauseth
