Is it possible to launch Blender in a mode where everything that appears in the Blender Console is sent to a file?

  • $\begingroup$ That's OK, mods can add the tags that are necessary to your question later. Creating new tags is generally not a good idea, because it makes organization more difficult. $\endgroup$ – CharlesL Feb 10 '14 at 18:41

On Linux/Ubuntu its ./blender > myLog123.txt from the working directory.

./blender &> myLog123.txt to include Stderr.

In Python you can do

import sys
file = open(filepath, "w")
sys.stdout = file
#...
#...
sys.stdout = sys.__stdout__ #reset
file.close()

to catch the console output while your script is running.

    $\begingroup$ Changing sys.stdout in Python apparently catches most of the console output, but not everything. $\endgroup$ – Garrett Feb 10 '14 at 20:23

On Windows,

  1. Open a command prompt (Windows KeyR, type cmd and hit Enter)
  2. Drag the Blender shortcut or exe onto the prompt
    C:\Users\Yourname>C:\Path\to\Blender.exe
  3. Add > %homepath%\Desktop\blender.log
  4. Hit return to start Blender with all console output redirected to blender.log on your Desktop.


For Mac and Linux, have a look here:
