Thank you for your response Justin,
The problem that I have is with the HDRP fog effect. Below is the simplest way to replicate the problem;
A brand new HDRP project (2019.4.0f1 LTS) -> add a UFPS character in the sample scene -> Play
Regardless of the height of the volumetric fog or enabling or disabling any of the options in the fog component, when the fog is enabled we will see the bottom half of the screen covered with a thick layer of fog. This is the fog component of the "Sky and Fog Volume" of the sample scene.
I have a lot to work on in my project and I'm really hopeful that in near future when I'll be starting to work on the atmospheric look of my game and the fog is important, this issue is resolved. Thank you in advance for your attention to this. If you need more information please let me know.
