ANISOTROPY NOISE

[KC149]

Hey Guys,
So I've noticed that by just changing the anisotropy value on a materiel any object with that materiel applied will render noisy, even with the de-noise on. In the exact same scene with the exact same material and setting, just with the anisotropy set to 0 will render fine and with the normal amount of noise expected but as soon as the value is set to something other that 0 there's an excessive amount of noise that just doesn't seem to clean up no matter how long it render for.

I just wanted to ask if anyone else has come across this and if there are any work around's.
Cheers Guys

Your model have proper UWV?

I don't have any screen shots hand but I've found this problem to occur with any material and yep its all mapped properly, the same thing happens with a UWW map and when unwrapped.

I have trouble reproducing this. Any example images/scenes/guidelines would be appreciated.
