Quebras ou travamentos

As causas mais comuns de quebras e travamentos do Blender são:

  • Não haver memória suficiente disponível.

  • Problemas com a placa gráfica utilizada ou seus controladores.

  • Defeitos no Blender.

Firstly, you may be able to recover your work with File ‣ Recover ‣ Auto Save….

To prevent the problem from happening again, you can check that the graphics drivers are up to date (Graphics Hardware), upgrade your machine’s hardware (the RAM or graphics card), and disable some options that are more memory intensive:

  • Reduce undo steps Preferences ‣ System ‣ Memory & Limits ‣ Undo Steps.

  • Using multisample anti-aliasing also increases the memory usage and makes the display slower.

  • On Linux, the Window Manager (KDE and Gnome for example) may be using hardware accelerated effects (e.g. window shadows and transparency) that are using up the memory that Blender needs. Try disabling the desktop effects or switch to a lightweight Window Manager.

To check memory usage by Blender:

  • On Windows, use Task Manager and sort by Memory.

  • On macOS, use Activity Monitor.app and open Memory tab. Alternatively, run top -o MEM.

  • On Linux, run top -o %MEM.

Informes de quebras

When Blender crashes, it writes out a text file which contains information that may help identify the cause of the crash. Usually, this file is written in the Diretório temporário directory.

This file contains a log of tools used up until the crash as well as some other debug information. When reporting bugs about crashes it can be helpful to attach this file to your reports, especially when others are unable to reproduce the crash.

Windows

On a crash, a file is written based on the name of the currently loaded blend-file, so test.blend will create a file called test.crash.txt.

Batch scripts are provided in Blender installation directory which may be run to obtain the Blender debug log and system info text files:

  • blender_debug_log.cmd is used in most cases.

  • blender_debug_gpu.cmd and blender_debug_gpu_workaround.cmd log GPU-related errors.

  • blender_factory_startup.cmd starts Blender with default settings which is recommended for debugging.

If the crash happens in Blender module, stack trace is also written to a file named blender.crash.txt. The path to that file can be found at the end of blender_debug_log.txt file.

macOS

After crash, macOS Crash Reporter shows a window after some time, or next time Blender is opened. Copy the text in the crash report and save it in a text file. That file should be attached to the bug report.

Linux

On a crash, a file named blender.crash.txt is written in /tmp directory.

Nota

More logs can be obtained by running Blender from Command Line and using --factory-startup --debug-all flags. See Lançamento a partir da Linha de Comando and Argumentos de linha de comando.
