Still issues with adjustments

Thanks for the latest changes. 

Still some issues tho. 

Often when I try and create a preset it will look ok for me but for instance, dark clouds and the ambient lighting is too bright so I try lower ambient light and sun brightness and it appears to be fine, however if people join the server or I start to move it slowly turns into the below view

This is the preset data that causes this result:

{
      "Name": "NewPreset",
      "Duration [seconds]": 14400,
      "Transition time [seconds]": 60,
      "Chance [0 - 100%]": 15,
      "Wind": 50.0,
      "Rain": -1.0,

      "Clouds coloring": -1.0,
      "Clouds attenuation": -1.0,

      "Clouds brightness": -1.0,
      "Atmosphere night brightness": -1.0,
      "Atmosphere night contrast": -1.0,
      "Night light brightness": 0.024,
      "Night light distance": 9.5,
      "Ambient light multiplier": 0.9,
      "Directional light multiplier": 0.3,
      "Reflection multiplier": 4.85,
      "Sun mesh brightness multiplier": 0.65,
      "Moon mesh brightness multiplier": 1.2,
      "Fog multiplier": 3.5,
      "Biome fog distance curve": 1.65,
      "Biome fog ambient saturation multiplier": 1.4,
      "Atmosphere fog height falloff": 0.013,
      "Atmosphere fog ramp start distance": 0.0004,
      "Atmosphere fog ramp end distance": 0.4619,
      "Volume clouds sky occlusion": -1.0,
      "Volume clouds atmospheric haze": -1.0,
      "Volume clouds sun color scale": 0.144,
      "Volume clouds mooon color scale": 0.262,
      "Override cloud config": 5
    },

I often adjust things still and they appear to make no difference or will appear to be fine until I move and then everything goes out of whack
 

More testing. 

In this example I would expect the ambient light to be very low as I have set it to basically nothing and setup the sky to be very dark however the actual view is bright still with no way to seemingly lower this. 

I have other presets that do appear very low but this seems to be a combination of some settings preventing this and may be one of them being "out of bounds" with its value or something because I find after adjusting a few things, nothing I adjust makes any sense as to what it changes, often nothing until everything gets weird and I ahve to delete the preset again and start over

      "Name": "NewPreset",
      "Duration [seconds]": 14400,
      "Transition time [seconds]": 60,
      "Chance [0 - 100%]": 15,
      "Wind": 50.0,
      "Rain": -1.0,
      "Thunder": -1.0,

      "Ocean": -1.0,
      "Atmosphere rayleigh": 2.25,
      "Atmosphere mie": 1.2,

      "Atmosphere night contrast": -1.0,
      "Night light brightness": 0.02,
      "Night light distance": 6.5,

      "Volume clouds sun color scale": 0.0,
      "Volume clouds mooon color scale": 0.262,
      "Override cloud config": 5
    },

So this is why I find the way this works to be strange. I am still on the same preset and I set all parameters to -1 and this reset the conditions now to normal. I ahve now adjusted only a few parameters, same as I was adjusting before, but now it looks as I would expect. 

I simply adjusted: 
"Atmosphere contrast": 2.5,
"Atmosphere brightness": 0.35,
"Override cloud config": 5

    {
      "Name": "NewPreset",
      "Duration [seconds]": 14400,
      "Transition time [seconds]": 60,
      "Chance [0 - 100%]": 15,
      "Wind": -1.0,
      "Rain": -1.0,
      "Thunder": -1.0,
      "Rainbow": -1.0,
      "Ocean": -1.0,
      "Atmosphere rayleigh": -1.0,
      "Atmosphere mie": -1.0,
      "Atmosphere contrast": 2.5,
      "Atmosphere directionality": -1.0,
      "Atmosphere fogginess": -1.0,
      "Atmosphere brightness": 0.35,
      "Clouds size": -1.0,
      "Clouds opacity": -1.0,
      "Clouds coverage": -1.0,
      "Clouds sharpness": -1.0,
      "Clouds coloring": -1.0,
      "Clouds attenuation": -1.0,
      "Clouds saturation": -1.0,
      "Clouds scattering": -1.0,
      "Clouds brightness": -1.0,
      "Atmosphere night brightness": -1.0,
      "Atmosphere night contrast": -1.0,
      "Night light brightness": -1.0,
      "Night light distance": -1.0,
      "Ambient light multiplier": 0.1,
      "Directional light multiplier": 0.1,
      "Reflection multiplier": -1.0,
      "Sun mesh brightness multiplier": 1.15,
      "Moon mesh brightness multiplier": -1.0,
      "Fog multiplier": -1.0,
      "Biome fog distance curve": -1.0,
      "Biome fog ambient saturation multiplier": -1.0,
      "Atmosphere fog height falloff": -1.0,
      "Atmosphere fog ramp start distance": -1.0,
      "Atmosphere fog ramp end distance": -1.0,
      "Volume clouds sky occlusion": -1.0,
      "Volume clouds atmospheric haze": -1.0,
      "Volume clouds sun color scale": -1.0,
      "Volume clouds mooon color scale": -1.0,
      "Override cloud config": 5
    },

What I can't fix, because it's on Rust's side:

Ambient light, Sun and moon light, Reflections, the Clouds sliders and four of the Fog sliders do nothing in the current Rust build, so the next update removes them from /wsetup. That's why your dark preset never got darker.

Rust takes about 30 seconds to settle the lighting after any change, so give a slider half a minute before judging it.

Sky contrast 4.1 together with Sky blueness 4.85 is what turns the sky black with the orange band. That's how the game draws those values. Its own presets keep both around 1.

I couldn't reproduce the fully yellow screen from your first screenshot on my test server. If it still happens after the update, send me that preset and the game time and I'll check it.
