Anisotropy Error

V-Ray V-Ray for 3ds Max Issues

hi there,

I am having issues with the anisotropy on a brushed metal shader…

I noticed a weird flickering in my rendered animation, but only on one of the shaders.
I test rendered 2 adjacent frames where the jumping clearly occured and pinned down the problem to the anisotropy of the shader, once I turned it of, the jumping in the reflections dissappeared.

After some googling I found a post by Neil Blevins about anisotropy atrefacts and messed up smoothing.
One of the objects in the frame I tested had a turbosmooth on it, once I set that to respect smoothing groups, the error seemed to dissappear.

Can someone confirm this or has any advice on how to avoid this issue?

EDIT: Nope, it DID fix the issues, or at least it should have. Since this was a mapping issue, I should the turbosmooth needed a couple of more support loops to even out the UVs…
Works now!

It would still be useful if you can get me a scene where this can be reproduced.

Best regards,
