I was just revisiting an old file and noticed the the principled anistropic setting was not working. Looked and the anistropic shader is also missing. Anyone else have this issue?
Haven’t checked, but are you sure you’re not using Eevee?
I think there are plans to bring aniso into Eevee, maybe that caused an issue with Cycles implementation? Don’t have a clue really. Will check next opportunity I get.
Actually that was it. Thank you @CarlG
