Arnold N AOV is flickering

[1525232224]

Hi,I got some problems. When i render with arnold,the N (default)AOV is very flickering,Just like there are too much noise and the more details the more flickering it gets. Can not use in NUKE.So what is the reason and is there any way to solve this.Thanks!

I think your N AOV is using a closest filter. Switch to some other filter that averages across samples (box, gaussian, etc.).

Thank you for your kind advice,I had tried earlier,gaussian is better than box and the defaut closest,but still have a little bit of noisy flickering.
