so I tried following this (somewhat dated) tutorial to create an anisotropic material.
Unfortunately no matter what I do, the objects don't look anisotropic at all.
Here's my attempt at following the tutorial:
Even if I just open a plain new file, add a geometry, an HDR map as the background and set the Anisotropic shader, it doesnt work:
The only way I could see any anisotropy, was by downloading the example blender file from the docs.
What could be missing from a plain new file, that the example file has? The cycles nodes look exactly the same.
