hi, I encountered a problem with the render mask function.
if I launch the whole image no problem but with the render mask it is blurry and with a loss of a lot of detail. Even with Denoise turned off. this happens with vray 6.1 on win10​​

Hey, visualtracing,

Thank you for submitting your report. It is normal to see a difference in quality between a bucket/progressive aka final render and an interactive one. However, if you see a difference between two final renders, please inform us and provide us with additional information, including a scene file.

Cheers, ​

HI

the two images are two final progressive renderings, non-interactive.
However, this evening I will prepare a file to send you.
Thank you​

HI,

I found the problem but I don’t understand why.
the problem is solved if I delete the second round carpet, I don’t understand how much trouble it can cause though.
Below you will find the two renders that are not interactive.

Hi @visualtracing ,

It seems like the issue is caused by this polygon selection tag. Removing the tag (or renaming it) seems to resolve the issue. I hope this is of help.
