I'm looking for a way to execute blender, in background mode (-b) and giving a python script (--python <filename>) which is available in the network. For example :

blender.exe -b --python  \\Host\Dev\blender_setup.py

Currently Blender is looking for the script adding the current folder from which the .bat was executed (or C:\Windows if the batch file was in a network path). I've tried many syntaxes (//, \, \\, "\...", etc) and apparently I can't without mapping a network drive. I always get something like :

OSError: Python file "C:\Users\flavio\Desktop\Host\Dev\blender_setup.py" could not be opened: No such file or directory

As you can see in bold, Blender is not looking in the right place

EDIT : Without mapping that network folder to a network drive and without simlinks. It would be too easy :)

Any clue ?

EDIT 2 : Waow, actually any network paths, even for .blend file, are not working. This is very tricky for a renderfarm. The following paths (no matter the /, //, \\, \\\\ etc) will give the same result :

blender.exe -b \\192.168.0.5\...\myFile.blend -a -x 1 -o

or

blender.exe -b \\HOST\...\myFile.blend -a -x 1 -o

Will give the following error message :

Warning: Unable to open 'C:\Users\flavio\Desktop\192.168.0.5...\myFile.blend': No such file or directory

(if the .bat file is on my Desktop)

    $\begingroup$ Basic UNC support is implemented: developer.blender.org/D298 This sounds like a bug/missing feature to me. $\endgroup$

It's fixed on Blender 2.71 for windows.

(As part of our network is still using XP we are stuck on 2.70a, and I didn't had the chance to test 2.71)
