float nh = saturate(dot (s.Normal, h)); //Make sure that
the return number isn't lower than 0 and greater than 1
float specPower = pow (nh, _Glossiness);
fixed3 specular = _LightColor0.rgb * specPower * _
SpecularColor.rgb;
//Result
fixed4 c;
c.rgb = (ambient + diffuse + specular) * (atten * 2);
c.a = s.Alpha + (_LightColor0.a * _SpecularColor.a *
specPower * atten);
return c;
