Crash after closing project

Hi there,

I have sometimes a full crash of Cinema 4D (R23) when closing a project. It seems it happens when I close the project close to the time when stopping an IPR render. Crash report is attached.

Thanks for checking!

Update, I just tested opening and closing without doing an IPR render. And it crashes still. So maybe not caused by the IPR then…

Hello @torebernhoft Thank you for sharing the bug reports!

Could you please let me know of your Cinema 4D and V-Ray (V-Ray > Help > About ) exact versions.

Also, does this situation reproduce on every scene or on a specific scenes only?

Additionally, could you please uninstall V-Ray and check if the crash is still reproducible. If it is, it might be best to contact the Maxon’s support.

Hello @viktor_angelov

Thanks for getting back to me!

I’m using Cinema 4D R23 and V-Ray 6 for Cinema 4D, update 2.1 (v6.20.01 from Feb 6 2024)

This can happen in any scene with V-Ray set as renderer. But it’s random if it crashes or not.

Almost like some v-ray internal background task is running and get’s interrupted. This is of course just a guess, but that’s how it feels.

It never happens if I set the renderer to Standard (C4D). No crashes. Even with V-Ray installed.

Also worth noting is that it might crash when quitting C4D too, if I have worked on a V-Ray project. Even if I close the project down first…

Hello @torebernhoft I have logged this into our system [VC4D-2214] and we will be investigating the crash thoroughly. We will reach out to you once we have more information.

Great! Thank you @viktor_angelov
