Crashing when compositing 2 scenes
Closed, DuplicatePublic


System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits

Blender Version
Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: rB0f45cab862b8
Worked: 2.90

Short description of error
When compositing 2 scenes together Blender crashes during the animation render. This seems to affect both Eevee and Cycles, although Eevee seems to crash sooner.

Exact steps for others to reproduce the error

  1. Open provided file of mobius strip
  2. Render out animation with compositing (crashes)
  3. Render out animation with "use node," for compositing turned off and it will finish.

EDIT: Here are the debug and crash logs created using factory_startup

Thanks for the report.

I am unable to reproduce the crash. I tested both 2.91.0 and 2.92 5424b4821d28.

Please open Blender's installation directory and double click on the blender_factory_startup.cmd. This will start Blender without user add-ons and create log files. Try to make Blender crash again. Once it crashes the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt (or simply type %TEMP% into the path bar of the Windows Explorer).

Tested using:
OS: Windows-10-10.0.19041.630-SP0 64 Bits
GPU: GeForce GTX 470/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 391.35
CPU: i7-950 @3.07 GHz SSE2 SSE3 SSE41
RAM: 8.00 GB

OK, just updated the post with all 3 of the crash files. It crashes pretty reliably on my end, but every once in awhile it will manage to render the while animation

This appears to be the same problem as T84324 and T83375. Could you please check the following:

  • Does the crash still occur when you open Blender's installation directory and double-click on the blender_debug_gpu_glitchworkaround.cmd?
  • Does the crash occur when using the most recent daily build of Blender 2.92?

Yes, the crash still occurs with blender_debug_gpu_glitchworkaround and I get the following errors

and also crashes on the newest experimental build

Also have both a GTX 1070 and GTX 970 in my system. I don't know if it's relevant, but it wasn't picked up by the report generator so I figured I'd mention it (also added to original post).

Thank you for the files. Unfortunately I can't reproduce the crash on my system(s) either, but it seems to consistently crash in GPU_texture_mipmap_mode for you regardless whether the GPU workarounds are enabled or not.
