Anisotropy

[inthemix7]

Hi
I have a with anisotropy material. Simple geometry (plate whith flat bottom).
after turn on anisotropy the circle appears on the bottom. Tried different types on closing the bottom but the result is the same, exept the size of that circle

Looks like normal smoothing is a bit off.
Either put faces on the inner part of the bowl all in one Smoothing group using edit poly or if memory serves me correct, throw a smooth modifier on it. It allows you to set smoothing to auto and just input an angle which it auto smooths with.
That'd be my guess.

it`s all in one smoothing group

Does mapping correct? Plug gradient ramp from anisotropy angle to diffuse and see how it looks.

if i understand correctly, here the result

upload the scene, it will be faster to solve

Do not know. with your file 3d  max is crashing on saving
It's something with your 3d model, will be faster to make new similar 3d object with the same settings

Mapping looks correct. Try to change anisotropy orientation from local axis to UVW in Corona material's advanced options. If that won't solve the issue, then it's most likely smoothing issue - add support loop near the transition between flat and curved portions of the plate.
