Corrupted BPR render

[system]

This morning I opened up a sculpture that I had worked on last night. When I opened the file, I noticed it was getting rather big (2.2 gigs), so I cleared the undo history and saved it. But it somehow got corrupted because now I’m getting these mysterious black lines when BPR rendering it. (Best Render works fine.)

I could go back to the most recent Quicksave, but I will lose some work. Is there anything else that can be done?

I’ve not seen anything like this before but what you could do is save the model as a ZTL through the Save As button in the Tool palette then load it into a clean project through the Load Tool button. Also you might try with a different material in case that has some effect on it.
