Vray denoiser cause "boxes region" images

Hi, some issues with vray denoiser, it couse some weird “boxing” area, it appear random, not in every scene, it much more visible in animation moving camera, below images left original render and right denoiser effect result, all texture disable.
i check all passes element, all good. also i tested with vray nuke plugin denoiser, the effect was same.

how to handle this issue?

Thanks

Would it be possible to send us that scene for investigation?
Also, what is the V-Ray and Maya version that you are using?

yes, i can send you the sample file, may i know where should i mail to?
we test vray 3.40.06 & 3.52.03 & 3.60.02 as for maya 2016 extension 1 sp5

You can send it to support@chaosgroup.com, just paste the thread name/link in the email.

Email sent.(with attachment) .this is what i do , create box & sphere and poligon plane fill the back ground (plane facing camera for matte painting) and put some random uv checker images.
create extra text & connect sampler info world position to extra tex rgb.
If i check the Consider for AA, the error occur.

Thanks

I replicated the issue but I’m not sure what’s causing it. Therefore, I can’t provide any workaround. The issue is in the developer’s hands now, I’ll keep you posted.
