Pitch claims

#1 Uhm, generally yes, you could set the drawing distance to that. You could set it to any value. There's no hardcoded limit of that I'm aware of that limits you in setting the drawing distance. Another story is, if you target audience can run this at decent frame rates, but that depends on the project requirements.

#2 There's allways a limit, because the type of the variable cant be bigger (uint has a max of 65535 etc.)

#3 Right, but that would assume a view distance max. of 65 kilometers. Enough for most applications I guess :-)

#4 The fact is (in your mission file):

new Sky(Sky) {
      position = "0 0 0";
      rotation = "1 0 0 0";
      scale = "1 1 1";
      materialList = "~/data/skies/sky_day.dml";
      cloudHeightPer[0] = "0.349971";
      cloudHeightPer[1] = "0.3";
      cloudHeightPer[2] = "0.199973";
      cloudSpeed1 = "0.0005";
      cloudSpeed2 = "0.001";
      cloudSpeed3 = "0";
      [b]visibleDistance = "10000";[/b]
      fogDistance = "3000";
      fogColor = "0.6 0.6 0.7 1";
      fogStorm1 = "0";
      fogStorm2 = "0";
      fogStorm3 = "0";
      fogVolume1 = "0 0 0";
      fogVolume2 = "0 0 0";
      fogVolume3 = "0 0 0";
      windVelocity = "1 1 0";
      SkySolidColor = "0.113 0.148 0.215 0";
      useSkyTextures = "1";
      renderBottomTexture = "0";
      noRenderBans = "0";
      renderBanOffsetHeight = "10";
      skyGlow = "0";
      skyGlowColor = "0 0 0 0";
         locked = "true";
         windEffectPrecipitation = "1";
   };

sorry, if I don't understand very well this post But I'm a frenchy guy and I've sometimes troubles with english understand :p.
