Maybe a stupid question, but I can’t find the answer anywhere.
What does the FX in FX Shaders stand for?
Thanks
The F could have something to do with “fragment”.
Just posting this because I want to follow the discussion in the open. 
When thinking of it, it could stand for reflective. However it seems redundant to use an abbreviation for denoting just one single word, rather than a sequence of words.
Agreed; that’s why I just edited my previous post.
FX is for eFfeCTs
(VFX => Video Effects)

Thanks!
F.X sounds like Effect when spoken out loud so it’s a common abbreviation not just for visual effects (VFX) but also for sound effects (SFX).
That’s what I wrote first but I hope there would be more to it.

I just assume that people’s native language is not English on these forums. I wouldn’t be so silly nor so arrogant 
English is not my mother tongue indeed and I know what fx generally stands for but then I stumbled on places where people talked about “fragment shader”. I even put a link to one of them in my first post.

An FX Shader can be a shader used for some kind of vfx, or may refer explicitly to a shader written for Nvidia’s FX Composer which was abandoned a decade ago, but you’ll often still see references to when researching shader stuff. This used CG or HLSL shaders, but are in a different form than what Unity can use directly. It could also be referring to ShaderFX, which is a node based real time shader system used by Maya.
In short, it’s not a specific thing outside of the context it’s being used.
