Shader compiler throws error when referencing file via #include

vvvv gamma bug
1

Hey, I’d like to use an external library in a shader without having to change it to be stride/sdsl specific. Therefore I tried #include but unfortunately the compiler can’t find the file and throws an error.

From the gray book:

According to git history this was added by @joreg .
Did you test this at that time?

That was probably based on my words. I never tested it though, I guess it needs some paths to be added to the compiler statement. But it would need a deep dive into the stride source code to know for sure.

Fixed in upcoming builds. The relevant commit can be found here.

Great! The file extensions could also include .fx .fxh .hlsli and maybe also lesser used ones like .vs .ps .gs .cs.

You mean the ones which get copied to the output folder on export? In any case feel free to create a PR for it.
