World's Atmospheric Pressure (Kpa)

[glenn52]

Can (which?) values in the *.xml files be altered to tweak atmospheric pressure?
Thanks.

The pressure is a product of the atmospheric composition. You need to change the molar values for "how much gas" and/or the temperature of said gases, and the pressure will change.

Atmosphere Composition

    <AtmosphereComposition>
      <SpawnGas>
        <Type>CarbonDioxide</Type>
        <Quantity>5</Quantity>
        <Name>CarbonDioxide</Name>
      </SpawnGas>
      <SpawnGas>
        <Type>Volatiles</Type>
        <Quantity>10</Quantity>
        <Name>Volatiles</Name>
      </SpawnGas>
      <SpawnGas>
        <Type>Pollutant</Type>
        <Quantity>2</Quantity>
        <Name>Pollutant</Name>
      </SpawnGas>
    </AtmosphereComposition>

The above is the XML section for Vulcan. Note that three gases are defined, you can include a new type definition for as many unique gases as you would like.

The quantity values, when changed, would alter the pressure - how much depends on the temperature.

Temperature

This established a curve that, depending on the time of day, returns what temperature (in Kelvin) the world atmosphere is at. Without this, it is constant.

Thanks, appreciate it...
