There is no documentation or tutorial on the internet of how to do anisotropic hair in Godot.
How the flow maps should look like, tips or tricks, nothing.
In the official documentation (Spatial Material — Godot Engine (3.0) documentation in English) there is a screenshot and short description, but no sample project.


If anyone has a sample project or detailed instructions with pictures would be appreciated.
Thanks in advance
