Quixel exported textures not behaving like they should I have the exported Quixel textures for the material "shiny brushed steel" but basically everything it does is make my materials follow the albedo only and they are dark, even with some fine HDRI images as environment light. I'd like someone with lighting/texturing skills to take a look at my scene and tell me what am I doing wrong. 
Of course, removing the albedo helped a bit, but then I lost imformation and the material didn't do what it was supposed to. 


EDIT: If I saw it well, the textures didn't upload along the file. I include the scene in a zip via google drive if that's fine by the answerer.

Did you use Quixels material setup? They created a node group in which you only plug in your textures. Here's the link:
