Bongo- Crashes while rendering using Nvidia Denoiser

Hi, if I run a still frame render using the Nvidia Denoiser, it works fine.
If I run a Bongo PNG sequence render, Bongo crashes while rendering using the Nvidia Denoiser.
Any Ideas ?

can you run the systeminfo command and post the result?

Any chance you could share your file? If it’s private, you can send it to us via

Are you rendering the still frame with Thea?

Hi Nathan, no, its all Rhino Render.
I installed Thea to test it a while ago.

When a crash happens does the crash reporter dialog appear? If so, have you sent in crash reports?

No, the crash reporter dialog doesnt appear.

So Rhino just disappears without leaving any trace?

Yes :slight_smile:

Does the crash happen when you disable the Nvidia denoiser for your Bongo render?

Hi @Mike_A,

Does it crash almost immediately when you start rendering, or only after a few minutes? Can you please keep an eye on your memory usage while rendering. Is the memory usage going to 100% just before the crash?
