I need a little help creating an executable python OS command for Blender (Windows and Mac). I am setting up a stand-alone blender package for a client to use. I have a python script that imports some data and I want to create an executable python script that runs OS commands to run Blender, run the python script and define the data directories.

This is a generic version of the Windows command I normally run to import the data, using the stand-alone version of Blender:

"C:\Users\username\Desktop\Package\system\blender\blender.exe" "C:\Users\username\Desktop\Package\system\version_data\CurrentVersion.blend" -P "C:\Users\username\Desktop\Package\system\version_data\BlenderScript.py" "C:\Users\username\Desktop\Package\input_data\\" -y

From my research I have worked out that I need to:

  1. import os
  2. make the directories in the command relative
  3. create an executable python file

My python experience is limited, but I believe it may be something like this:

import os

pythonDirectory = os.path.dirname(os.path.abspath(RunThisApp.exe))  # get the current dir of this file (which would be: C:\Users\username\Desktop\Package\)

os.path.join(pathDirectory, "//system\blender\blender.exe" "//system\version_data\CurrentVersion.blend" -P "//system\version_data\BlenderScript.py" "//input_data\\" -y)

However I had a look at this post and was a little fuzzy as to the best way to do this:


Then I could possibly use PyInstaller to create the python executable files. Which seems to be the simplest method suggested here:



Am I close to the correct result here? I am guessing my syntax is off. I need to make sure it works for both Windows and Mac.

It should also be noted that the separate python script I run to import data into blender (which I have been using and updating for a couple of years), refers to OS arguments to get the desired path of data to import, so I need to make sure that I maintain that connection. Here is an example:

IMPORT_DATA_FILENAME = sys.argv[4]+'data.txt' 

Any advice or input would be greatly appreciated. Chris Lee

  • This question does not appear to be about Blender within the scope defined in the help center.
If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ Unless I am misunderstanding, this seems like more of a Python question than a Blender one. I think this would be better suited to one of the programming focused StackExchanges. $\endgroup$ – Ray Mairlot May 18 '17 at 11:01
  • $\begingroup$ You may be correct. I will do that. $\endgroup$ – Chris Lee May 18 '17 at 16:22
