Wiring up Anisotropy in an Unreal Engine Shader

General / 11 December 2020

I did it wrong in my post. You should apply some simple math on the flowmap for it to work correctly.
Find this enlightening post from UNREAL GEMS to get the correct way on how to utilize flowmaps for anisotropy

[edit] The below approach is not completely correct. Follow the above Tutorial to get it right!

This is obviously for the case you do not want to map your object. so a triplanar mapping.
Ofc this is also possible with normal UV's 

you can find an anisotropy map here:
