I ran the render again and it didn’t crash.
I noticed that a lot of ram was being used (saw it in task manager). I had a fair number of programs open so I closed them and memory usage went down to ~50%. And I got no crash.
Maybe it’s ram related.
I used to have this problem when I only had 16 Gb of ram so upgraded to 32 Gb. But when I only had 16 Gb there were screen drawing issues when a render was running. I don’t see those issues these days with 32 Gb. (There were black rectangles on screen were windows should have been. I think that Windows was running out of memory to buffer window images.)
I’m going to kick off a new batch of renders and see if things fall over then. I will upload the crash report and file if I get a crash.
It would be nice if Rhino saved enough info to be able to upload crash reports at a later date. And a way to launch the reporting dialog by hand.
Is there documentation available that says what’s needed for a crash report? Are there hidden (or not obvious) files? Or is there only the text file and crash file on the desktop?
