Light in Clear Sky game is too bright compared to the original engine

[argosurvivors]

Describe the bug
New render settings turned light in game up to a very high value, much higher than original.
This makes different atmosphere in the game that is supposed to be dark and scary.
There are noticeable blinding reflections on light colored materials such as concrete, clear sky soldiers uniforms, wet surfaces, weapon edges. It is very distracting and breaks the focus from gameplay.

In my opinion light should be around 10-15% lower to match the original game appearance.
Screen Space Shaders did compensate this problem but since they are no longer supported the engine should adapt to match original amount of light without additional shaders.

Screenshots, videos
As shown on the picture the brighness without SSS shaders

Picture bellow shows game with SSS, much closer image to the original game

Try to delete your user.ltx from the _appdata_ folder. All of these brightness problems might be caused by SSS settings.

I tried, it doesnt help, the new render settings makes everything look like glossy plastic and makes an unnatural contrast in the sky. For example the OpenXRay Release Master Gold build 9619, Jun 9 2025 had beautifull ambient tones similar to the vanilla game and the sky was very nicely blended. The screenshot bellow is that version without any edited shaders.

As I told you, please, don't use this build number. I'm not tracking this number, it's there just for historical reasons!
Use BOTH first two lines of the log. Not just one.
