Can't get a skybox to work

[AveryTheKitty 2626]

Hello, I'm trying to change Altis's skybox to use a custom one I've created.

 

class CfgVehicles{};
class CfgWorlds
{
	class DefaultWorld
	{
		class Weather
		{
			class Overcast;
		};
	};
	class CAWorld: DefaultWorld
	{
		class Weather: Weather
		{
			class Overcast: Overcast
			{
				class Weather1;
				class Weather2;
				class Weather3;
				class Weather4;
				class Weather5;
				class Weather6;
			};
		};
	};
	class Altis: CAWorld
	{
		class Weather: Weather
		{
			class Overcast: Overcast
			{
				class Weather1: Weather1
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_clear_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_clear_lco.paa";
				};
				class Weather7: Weather1
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_veryclear_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_veryclear_lco.paa";
				};
				class Weather2: Weather2
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_almostclear_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_almostclear_lco.paa";
				};
				class Weather3: Weather3
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_semicloudy_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_semicloudy_lco.paa";
				};
				class Weather4: Weather4
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_cloudy_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_cloudy_lco.paa";
				};
				class Weather5: Weather5
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_mostlycloudy_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_mostlycloudy_lco.paa";
				};
				class Weather6: Weather6
				{
					sky = "A3\Map_Stratis\Data\sky_clear_gs.paa";
					horizon = "Test_Skybox\Data\sky_overcast_horizont_sky.paa";
					skyR = "A3\Map_Stratis\Data\sky_overcast_lco.paa";
				};
			};
		};
	};
};

So far, it hasn't work and the skybox doesn't change at all. Is there anything I'm missing?
