Shader Problem

I have a problem to reuse my old shader i dont know whats the problem of the highlights

always render vertically even i change the position of my uv maps always got a same result

please help me to fix this

see my shader code hope it will help

hader "Toon/Hair" { Properties { _Color("Color(RGBA)", Color) = (1,1,1,1) _MainTex("Texture", 2D) = "white" {} _SphereAddTex("Texture(Sphere)", 2D) = "black" {} _Shininess ("Shininess(0.0:)", Float) = 1.0

     _ShadowThreshold ("Shadow Threshold(0.0:1.0)", Float) = 0.5
     _ShadowColor ("Shadow Color(RGBA)", Color) = (0,0,0,0.5)
     _ShadowSharpness ("Shadow Sharpness(0.0:)", Float) = 100
 }
