Crash with Raytraced

Rendering

Hi Nathan,

I encounter the exact same problem since the last few updates. The Rhino instance disappears without any crash report, Autosave or anything that would give any information. It might be .NET7? It happens only in cycles view, but mostly after about 5 or 6 seconds, even for extremely simple geometry. setting a camera focus point makes it crash faster (not measured, but from sensation) here my sysinfo:

Thank you very much in advance if you take the time to look into this problem.

UPDATE: I’ve just updated the nvidia driver (creator driver, not gaming driver) and it now takes about 8 seconds before crashing AND gives the following info before crashing:
Cycles: fallback to CPU, kernel still compiling

therefor these infos in sysInfo change:
Standard graphics configuration.
Primary display and OpenGL: NVIDIA GeForce RTX 4070 Ti (NVidia) Memory: 12GB, Driver date: 7-14-2025 (M-D-Y). OpenGL Ver: 4.6.0 NVIDIA 577.00
> Accelerated graphics device with 4 adapter port(s)
- Windows Main Display attached to adapter port 0
- Secondary monitor attached to adapter port 1
- Secondary monitor attached to adapter port #2

2nd UPDATE:
I’ve been able to send in a crash report. done it twice. should i continue to send them while testing or do you prefer not to be spammed?

Bongo 2 & Cycles crashing during rendering

Please make sure you fill in your email address so that I can find it in our database. I have not yet seen any from you there tied to your address.

Please update Rhino 8 to the latest available.

Make sure you have the latest GPU driver installed as well. When you do update it is a good idea to check the Clean Install option via the custom install options of the driver installer.

I don’t see Bongo in your plug-in list. I take it your crash is unrelated to Bongo 2 + Cycles as in this thread?

I did several times with my email, very strange it doesn’t appear in your list. I’ll try again.

That’s what I’d done and it had become a bit more stable (8 seconds instead of 5 before crash). I’ll try the game ready driver now. This worked once I had problems with maxwell render.

It’s the closest thing to my problem I could find. I don’t use bongo, but the description fits very well. Very similar GPU; only in cycles and after about 5 seconds, he also uses studio drivers. Do you prefer me to open a new thread?

I’ll do all the updates first and will post here or in a new thread if I have news.

Moved to new topic.

It is unclear if you updated to the latest Rhino 8 version yet. Please ensure you update to latest available Rhino 8, rerun _SystemInfo and post the updated result.

I’m looking at your customer page with the email that you use with cloud zoo. For that at the moment no associated crash reports.

You could, with the crash reporter dialog still open, look on your Desktop to find the file called RhinoCrashDump.dmp or RhinoCrash.dmp. ZIP that and upload using our upload tool, I have prefilled my email address so I get notified when the upload is complete. Please also copy the link to this discussion in the comments box so I know what the upload notification is related to.

The studio driver is typically better. Did you install this driver using the clean install option?

Also make sure that before you reinstall your driver you have updated your Windows fully.

Sorry the late response. I tried one update after the other. However, I’ve updated everything. (hopefully). Here the systemInfo:

I am sadly unable to do more than click the send button on the crash report with my email. I am not able to tell why it wouldn’t arrive in your list.

Yeah, I switched back to the studio driver. It appears to be the 577 version like on your link. I usually get the latest version from the nvidia app.

I’ve done the upload like you described. Thanks for that alternative way. I hope it arrives like this.

hope to read from you soon

Thank you for sending in a file. Unfortunately this is a .3dm file. I am in need of the RhinoCrashDump.dmp file instead - note the file extension.

7

Thank you for your response.

I’ve been able to reproduce the crash by moving the cycles view a lot around while it starts rendering and upload the crashDump.dmp with your link. (sorry for the useless file before)

8

Thank you, the new upload contains indeed the file I needed to investigate. The crash is actually not happening in Raytraced or Rhino Render (Cycles), but rather in the post effects pipeline - in denoising to be specific. That is done by a separate built-in plug-in. You could turn off the denoising until that is fixed.

Thank you very much!

Hi @benedict,

I’ve logged the crash - you can follow it’s progress here.
