Please prefix your issue name with one of the following: [BUG] [PROPOSAL] [QUESTION]

Retopoflow Version: 3.4.3

Blender Version/Hash: 4.0.2

Platform Version/Distribution: Windows.

 

Issue:

Most studios install addons on a central shared server, to avoid having to install all addons to each and every computer.
For security reasons, our addons filer server is readonly.
But Retopoflow, tries to write its temporary or config files to the addon directory, which is read-only, so it fails, and prevents the addon to work.

It would be a lot better to write on the usually advised data directory (which is C:\Users[UserLogin]\AppData\Roaming\Blender Foundation\Blender\4.0\datafiles...... ).
Blender even provides a way to automatically get the path :
bpy.utils.user_resource("DATAFILES", path=yourSubDir, create=False)
Doc : https://docs.blender.org/api/current/bpy.utils.html#bpy.utils.user_resource

 

Here is our current workaround :

Completely disable the updater (we don't want the users to start an update themselves, anyway, as it's the admin job).

In RetopoFlow\config\options.py , replace this :
Options.fndb = get_path_from_addon_root(retopoflow_files['options filename'])
by this :
Options.fndb = bpy.utils.user_resource("DATAFILES", path=retopoflow_files['options filename'], create=False)

In RetopoFlow\config\options.py , replace this :
return get_path_from_addon_root(retopoflow_files[key])
by this :
return bpy.utils.user_resource("DATAFILES", path=retopoflow_files[key], create=False)
