Super long render often crashes on Image Save
Posted: Tue Nov 16, 2021 10:51 pm
Hi there,
I know this is a bit of a long shot but I wanted to record it down in case it may lead to something.
I'm doing a lot of Baking using Houdini 18.5.596 & Octane 2020.2.4.0 on Windows 10 with a mix of 1080, 1080Ti, 2080Ti, A4000 & A6000 cards.
The bakes can run for several days. The problem is that the render crashes as it's saving the image. The renders are 16k in size, are EXR format, no render passes, no RLE compression and no EXR Layers. I've even tried disabling asynchronous file saves to test.
What did seem to be successful is keeping the samples low. I started with 16000 which meant ultra clean renders but no renders were able to save (after 2+ days of rendering) and so i tried 128/256 as high speed tests and these saved successfully! So i've been increasing the sample count to around 8192 which as you see in the screenshot, does let some frames finish - but not all.
As I said, i know this is a long shot but could there be any ideas on what may be happening here ? It's terrible to loose several days of rendering as the image is saved at 100% complete : (
Thanks so much!
