Help with v-ray denoiser

[melanie_alter]

Hi, hopefully I came to the right place for help here. In my recent renders I’ve noticed that my reflections blur out or even disappear when my render is complete. After days of troubleshooting and researching, I realize that it’s specifically the v-ray denoiser that is causing the issue. This never used to happen, and it only started happening after I installed the new update. I’m hoping it’s not a bug in the update but if anyone has any helpful information on how to fix this, that would be greatly appreciated

I use vray 6 and my usual render settings are RTX, medium quality, v-ray denoiser (however I’ve been resorting to nvidia ai denoiser which is poorer quality but at least I have proper reflections).

thank you in advance!

HI, thanks for posting. What host app do you use (is it 3ds Max). Could you share an image or a video that shows the issue? Do you have the issue with a simple scene for instance a box an a basic VRayMtl and a light?
