Crashing in Vray 7 (current)

[torebernhoft]

Hey,

Had a lot of crashes in Cinema 4D R23 and moved to R25, and that helped but still some crashes. Here's the BugReport from my latest crash. It happened when I used IPR and did some updates to the light-mix.

Mac Pro 7,1. MacOS Monterey.

Hello torebernhoft,

I tried to reproduce the issue on my end, but I was not able to encounter the same behavior. To better understand what’s happening and assist you further, could you please provide the following?

• A screenshot of the layers you are using in the VFB.
• A video showing the crash occurring.
• A scene where the issue is reproducible.

Thank you.

Hey zhanet.georgieva,

Thanks for looking into it! I have been testing more, and it's difficult to know when and what is causing it. But that said, yesterday I got job that was urgent so I had to move fast and tried turning off de-noising when using the VFB (and only turn it on on production render). And it did not crash during an intense 10 hour work session, so maybe it's the de-noiser. I am using the Intel Open Image one. I could use the de-noiser in VFB if not doing live changes, I think that's when it happens.

Hi again zhanet.georgieva ,

It's very stable on production renders, no crashes so far. I also use distributed rendering from my Mac with Ryzen PCs as nodes. Works flawlessly.

VDB and also sometimes AUR volumetric renders is prune to crash during VFB sessions with live changes to these. So the problem with crashes during VFB is that you lose work...

Hello torebernhoft, can you please test if the problem occurs when modifying the lights in your project (adding, removing, renaming) and performing IPR?
