Sudden crash after render finished - no image, no logs In 2.8 I have a project which suddenly does not render single frames at full resolution. The set evolved over a few weeks with no problems.

Now if I render a still at target resolution it will finish the render and than totally crash out. No log nor message nor image is written, render window and main window just disappear.

No system overload, 50 % memory, I already reduced threads. Also checked temp file path, permissions, everything. I compared all render settings with an older file version and disabled composing flag. Updated to 2.81a.

Render at 80% works. I tried to hide everything in the scene at full resolution: crash. The task manager shows a spike in GPU 3d at the moment of crash.

Is there a hidden process between rendering and writing the final image?

And no, I can't share the project but will try to answer any question.

Thanks,
Carolo
The solution:

My own question (process between rendering and writing) led to the solution. Actually, there was a "SurfaceDrawing-Something" in the scene. Must have been a mistyped sculpting action. Whatever it is, it invokes a postprocessing which obviously is very hungry at some 30k resolution.

So watch out for strange elements in the outliner!
