How to make handmade shader from Unity4 to work in Unity5?

[DennyTX]

i have simple shader that works ok in assembly for KSP 1.0.5 for Docking camera (KURS style)

                    nightVisison = new Material(
                        "Shader \"Nightvision\" {" +
                        "    Properties {" +
                        "        _MainTex (\"MainTex\", 2D) = \"white\" {}" +
                        "    }" +
                        "    SubShader {" +
                        "        Pass {" +
                        "            Blend SrcColor DstColor" +
                        "            SetTexture [_MainTex] {" +
                        "                constantColor (" + nightVisionArgs + ")" +
                        "                combine constant + texture" +
                        "            }" +
                        "        }" +
                        "        Pass {" +
                        "            Blend SrcColor DstColor" +
                        "            SetTexture [_MainTex] {" +
                        "                combine texture * previous" +
                        "            }" +
                        "        }" +
                        "    }" +
                        "} ");

but it want not work in KSP 1.1.2. As i heard  there are many changes in work with shaders in Unity5 

Is here any simple way to quick adaptation for Unity5?

Thanks for your time.
