I have a bunch of blend files, each in their own directory with supported files wherever necessary. I want to configure all the blend files to use relative paths. I can open each of them and do File > Externel Data > Make all paths relative. But since I've a lot of blend files, this is time consuming. Is it possible to do this via python script?

  • $\begingroup$ Are they all in one directory or something? $\endgroup$

  • $\begingroup$ No, they're in different directory. But I can run the same python script for each blend file. That, I've got it covered. I need to know how to set this setting via python for a single blend file. $\endgroup$ Apr 4, 2021 at 17:44

    $\begingroup$ Have you tried this? docs.blender.org/api/current/… $\endgroup$ Apr 4, 2021 at 17:49
  • $\begingroup$ Thanks! I think that will work. I'll try it. I'm new to blender. How can I search for such things? i.e. how to do some things via python which I know how to do in GUI. I tried looking at blender python documentation, but I couldn't make head or tail out of it $\endgroup$ Apr 4, 2021 at 17:53

    $\begingroup$ In Preferences > Interface, turn on Python Tooltips. It will show you what to call in Python in the tooltip when you hover over a button. $\endgroup$

This will make all paths relative and then save

import bpy

You can run this from the shell like this. This should make all paths in file.blend relative

blender --background file.blend --python-expr 'import bpy;bpy.ops.file.make_paths_relative();bpy.ops.wm.save_mainfile()'
