Z Shader crazy export problem

Hi Guys,

I am using a Shader by writing a first pass to the Z buffer so that I can get a nice opacity blend off. Everything is great in the unity engine, but when I export the data, I get weird pink shader issues. I have added a video to show you what I mean. The export is the version with issues, and as you can see, running it in unity works fine.

Why is this happening? Does anyone know?

Here is the video:

by the way in the code, I use material.SetFloat("_Alphamult",2); to adjust the transparency over time

Any Ideas?

For anyone interested, it turns out that the shader that it switches to simply didn't compile for runtime, so an alternative was to reference the shader through a script, put it in a global variable, and access that.
