pyluxcoretools won't render a bcf file that blendluxcore renders fine

[emogenet]

Hello,

I have a scene in blender 2.93.5 I am running blendluxcore v2.6, github 78ed64744d60f28f03e4a735254b637f2b32973d from Dec 27, 2021 I am on Linux Ubuntu 20.04.4 LTS (focal) I run Python 3.8 PySide is not installed

The scene renders fine in the blender window in "render preview" mode It also renders fine when I press F12

However, when I save it to a .bcf file (via LuxCore FileSaver in binary mode) and try to render from the command line using the following command:

python3 pyluxcoretools.zip console /tmp/luxcore/rampe.lampes_LuxCore/00001.bcf

I get the error shown below at the end.

It looks like it is deserializing the textures fine but fails to find them after deserialization ...

The BCF file is 220 megs, so I'm not even going to try and attach it to this issue, but you can download it here:

(220 megs) 00001.bcf

or alternatively : curl 'http://95.217.220.241/00001.bcf' > 0001.bcf

Here's the error message:

To try and understand what happens, I straced the pyluxcoretools command.

Turns out after each Loading serialized image map: message is printed, a crapload of data is indeed read from the bcf file (lotsa read and brk syscalls) , but there are neither an open or a write syscall anywhere to be seen in the log.

It eventually gets to a stat("/tmp/tmptd9ucxy7.jpg", 0x7ffcfdb47e80) system call which - unsurprisingly - fails.
