    Hello guys, I have a question from shader experts
    Why this shader is just Pink in the last version of Unity?

    Code (CSharp):
    1. Shader "Elementals/Reflection Blur Fresnel"
    2. {
    3.     Properties
    4.     {
    5.         _MainTint ("Main Tint", Color) = (0.5,0.5,0.5,0.5)
    6.         _MainTex ("Texture", 2D) = "white" {}
    7.         _NormalMap ("Normal Map", 2D) = "bump" {}
    8.         _SpecularMap("Specular Map", 2D) = "white" {}
    9.         _Cube ("Cubemap", CUBE) = "" {}
    10.         _ReflectionMap ("Reflection Map", 2D) = "white" {}
    11.         _Blur ("Blur", Float) = 0.5
    12.      
    13.         _SpecColor ("Specular Color", Color) = (0.5,0.5,0.5,1)
    14.         _Shininess ("Shininess", Range (0.01, 1)) = 0.078125
    15.  
    16.         _RimColor("Rim Color", Color) = (1,0,0,1)
    17.         _RimPower("Rim Power", Float) = 100
    18.  
    19.         _FresIn("Fresnel Mid", Range(0.001, 1.0)) = 0.25
    20.         _FresOut("Fresnel Zovniwn", Range(0.001, 1.0)) = 0.25
    21.     }

    What changed in the last version of unity that makes this shader useless? It works fine with Unity 4.3

    It seems to be working in 4.6. Can you post the error message?
