I wanna try to change my fly's skin. So i try to do with 3 steps:     
1, made a new skins file "Tu-160.skins"   
models 
{ 
lod = {"Tu-160", 1000000}; 
    collision = "Tu-160-COLLISION"; 
}   
argument 
{ 
    argument = 70;   
    skin 
    { 
        value = 0.0; 
        material = {"Body", "standart", "Tu-160.BMP"};   
    }   
    skin 
    { 
        value = 0.1; 
        material = {"Body", "standart", "Tu-160-1.BMP"}; 
    }   
}   
2,add some codes in Scripts\Database\db_countries.lua:    
cnt_unit("{12F005C2-F9F1-4BD7-ADA0-AF169A7D8D78}", "Tu-160", { 
color_scheme("{FC853FD4-F2FE-4328-9498-7CE054338D1D}", "AF Standart"), 
     color_scheme("{FC853FD4-F2FE-4328-9498-7CE054338D2D}", "AF Standart 2"), 
}),   
3,add some codes inScripts\Database\planes\Tu-160.lua:   
ColorSchemes = { 
color_scheme("{FC853FD4-F2FE-4328-9498-7CE054338D1D}", _("AF Standart"), 0), 
     color_scheme("{FC853FD4-F2FE-4328-9498-7CE054338D2D}", _("AF Standart 2"), 1), 
},   
then , I can select "AF Standart"or "AF Standart 2" in game.  
but the skin didn't change,whatever i choose ,  
my plane just show the "Tu-160.bmp".   
PS:how should i understand the "Tu-160-COLLISION"
