Artifacts in cryptomatte mask

[Alex_M]

Hello. I'm getting artifacts in the cryptomatte mask when I preview it with the "Show preview when selected" button. Please check the screenshots below. The first one is with increased contrast to show the artifacts better, but it's also visible in the pure render (the 2nd image).

Hi, thanks for posting. I am not able to reproduce this issue in a simple scene. I am testing with 3ds Max 2024 and V-Ray 6.20.06 CPU. Are you using CPU or GPU? Are you getting this result in every scene, even a new simple scene?
Could you archive and send us the scene that you have issues with for review?

I'm using CPU. It happens only occasionally, if I remember correctly. Ok, I will send you the scene as soon as possible.

I've just submitted a ticked with the max 2023 scene and a .vrimg file. The ticket number is 250577.
