SetDynamicObjectMaterial

[Undercover]

Такой вопрос,почему не меняет текстурку?

    for(new i = 0; i < sizeof(Pravo_Up); i++)
    {
        Pravo_Up_Platform[i] = CreateDynamicObject(19353,Pravo_Up[i][0],Pravo_Up[i][1],Pravo_Up[i][2],Pravo_Up[i][3],Pravo_Up[i][4],Pravo_Up[i][5],1,-1,-1,200,200);
        switch(random(5))
        {
            case 0: SetDynamicObjectMaterial(Pravo_Up_Platform[i], 0, 19353, "MatTubes", "RedDirt1", 0);
            case 1: SetDynamicObjectMaterial(Pravo_Up_Platform[i], 0, 19353, "MatTubes", "GreenDirt1", 0);
            case 2: SetDynamicObjectMaterial(Pravo_Up_Platform[i], 0, 19353, "MatTubes", "BlueDirt1", 0);
            case 3: SetDynamicObjectMaterial(Pravo_Up_Platform[i], 0, 19353, "MatTubes", "YellowDirt1", 0);
            case 4: SetDynamicObjectMaterial(Pravo_Up_Platform[i], 0, 19353, "MatTubes", "PurpleDirt1", 0);
        }
    }
