I copy-pasted the shader example from https://github.com/bevyengine/bevy/blob/main/examples/shader/shader_custom_material.rs which worked well. However, I want to put the shaders in their own files so I don't need to have them inline in the rust script.
I tried using include_str! to include the shader file as a string, which i thought would do the same as having the shader in a raw string literal, however now this error happens when running the game:
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value:

I'm using bevy 0.5, and all the code is at https://gist.github.com/teevik/e7f419231a529e777d20ace06cac80b7
