hi everybody!
I tried fewdays for this problem
Changing filter size value several time but it's not help for me.
I know octane has no antialiasing filter.
But i think this probelm from antialias.
Anyone has same problem with FiberFX hair and have good solution?

Perhaps the hair fibers are too thin. Can you test your scene with more thick fibers?
If you want to share the scene I could test it here.

I think that the main problem is that the hair is too thin. With a 40% fiber width the render works better. Also a bit of DOF effect could help with hair rendering.

But I think that the big problem in this scene is the "Fiber Kick" effect that you have at 10% ... it introduces a high frequency pattern in the hair geometry that seems an aliasing problem.
