Exported shader's output is black
I am developing an application which can export unity shader files (.shader), depending on the user's input. At this moment, I have accomplished that the shader is correctly exported (if I use it in the main project), but when using that shader in a separate project, its output is unlit pitch black, although it does not show any errors.
I'm out of ideas about where am I failing to initialize the shader, or if I am missing something. Any help is heavily appreciated, I've tried to solve it during the last months, to no avail.
The build of the application is here., if you want to try another examples (the shaders can be lit or unlit, depending on the user's input).
"You can create a shader by clicking the desired options, then "Save Shader", and then choose the desired folder to export. "
The code of the output shader is the following. You can just copy/paste it to a new .shader file, and assign it to a material:
Shader"Shaderonomicon/New Shader"
{
SubShader
{
Blend SrcAlpha OneMinusSrcAlpha
Pass
{
Tags { "Queue" = "Transparent" }
LOD 100
