Has anyone been able to get anisotropic friction to work? In that case I would love to know the settings for the material. I have noticed absolutely no difference at all in the “frictional” behavior of a collider when trying out different direction2, static2 and dynamic2 values. Initially I set the direction 2 vector to the direction I wanted my friction 2 to work, then I tried the inversed approach - setting the friction2 to a lower value than the friction1. And then I triad different values for the coordinates and static and dynamic frictions - but absolutely no difference what so ever could be noticed. The only time there is a difference is when I change the friction values for friction 1 - the collider changes behavior accordingly. But never when I change the friction 2 values.
I just found this out from nVidia docs;
Anisotropic Friction¶
Friction on a surface in PhysX 2 could be configured to be stronger in one direction than in another. This is no longer supported in PhysX 3, and there is no known workaround that will give comparable behavior.
Bummer …
Feels a bit strange that Unity still has those properties in the Physics material then, since Unity 5 uses PhysX 3.x
Damn!
Lost 2 days trying to make it work… Why is it still there in Unity 5.x ? Why is it still mentionned in the documentation ?
Since the beginning of my new project 3 weeks ago, I’m facing fonctions that do not work the expected way …
Did nothing productive since 3 weeks… I think I’m gonna turn to CryEngine.
Searching for same problem I found an answers thread also stating that PhysX 3 does not support it: Friction Direction 2 work in Unity 5? - Questions & Answers - Unity Discussions
Can Unity please answer if it no longer works and if so why are the options still there and still documented?!
