In most cases it's the download link on the luxcorerender home page, but I also tried it with the daily 2.5 build that you linked me to (launched pyluxcoretool from inside blender in this case. 2.4 I typically unzip in to a directory and launch directly from the executable).

Re: PyLuxCore Tool Error ( v2.4, all scenes)
You can not mix different versions: the .bcf is created by the BlendLuxCore installed in Blender and then read by the PyLuxCore Tool you are lunching. Be sure to use binaries coming from the same version.
Re: PyLuxCore Tool Error ( v2.4, all scenes)
Yes, I know... I originally posted the issue using the 2.4 package downloaded and installed from the homepage. Ive now done this on 3 different computers, all of which give me the same error.
When you suggested trying a 2.5 daily build, I did that as well - I uninstalled 2.4 on one of my systems, installed the 2.5 daily build, exported, and attempted to load the resulting bcf in pyluxcoretool launched directly from the blender interface (to make sure I wasn't mixing versions). This also did not work, though I can't confirm that it's the exact same error message, as the contents of pyluxcoretool's console windows are blank when launched from blender directly.
Re: PyLuxCore Tool Error ( v2.4, all scenes)
I can confirm the same behaviour described by gecko (Windows 10 v1809, Blender 2.90, LuxCore 2.5 alpha as of commit 9a0caab from 2 days ago).
It happens with all binary exports, either with Blender language set to "English" or to "Automatic".
Also modifying decimal and thousand separator in Windows control panel does not change the behaviour (I have Italian settings in Windows, but I manually set decimal separator to point and thousand separator to comma - the standard Italian setting is problematic for me with some other software. Both settings show the problem).
The error messages look identical to those described in this old issue (which was Linux-specific by the way):
https://github.com/LuxCoreRender/LuxCore/issues/80
The problem is also present when using Blender 2.83.5, while exporting with Blender 2.82 seems to solve it (same identical BlendLuxCore version in all Blender versions).
More specifically, when using the bcf exported from Blender 2.82, the render process starts without problems. At the moment of clicking "Finish job" on PyLuxCoreTool NetConsole, this error is triggered (which seems to me unrelated to the one in this thread):
Edit: attached you can find the two bcf generated with Blender 2.82 and 2.90.

Re: PyLuxCore Tool Error ( v2.4, all scenes)
I installed Blender 2.83.5 and it continues to work fine on Linux so I assume it is a Windows only problem.
Re: PyLuxCore Tool Error ( v2.4, all scenes)
It happens also with text export, some material IDs are output with thousands separator (comma in my case), no matter the language setting in Blender:
Code: Select all
scene.materials.Material2294200882568.id = 3,364,224
scene.objects.22943803418800.id = 1,326,487,202
Re: PyLuxCore Tool Error ( v2.4, all scenes)
Glad you could confirm I'm not crazy, thank you! Is it helpful to submit a bug report? Seems to be a recurrence of the same issue that Dade cited earlier, just more persistent. Let me know if there's something I can do to help make sure this gets fixed.acasta69 wrote: ↑Tue Sep 08, 2020 7:40 pm It happens also with text export, some material IDs are output with thousands separator (comma in my case), no matter the language setting in Blender:Code: Select all

In the meantime, I would assume that it would be possible to semi-manually strip out inappropriate commas (eg with a regex find/replace). However, this would obviously only work with the text export not binary... and pyluxcoretool does not let me load the text export file - the file->open dialog box is locked to *.bcf files only. Is there a trick to doing this?
Re: PyLuxCore Tool Error ( v2.4, all scenes)
Actually this issue has already been submitted:
https://github.com/LuxCoreRender/LuxCore/issues/390
I don't know if it's possible to mangle the binary file, I don't think so.gecko wrote: ↑Tue Sep 08, 2020 8:30 pm In the meantime, I would assume that it would be possible to semi-manually strip out inappropriate commas (eg with a regex find/replace).

But if you can adjust the text files as you described, then I think you can load the scene with LuxCoreUI and export the binary from there.
Re: PyLuxCore Tool Error ( v2.4, all scenes)
Well that worked for the default scene, and I can confirm that the stray commas are definitely the issue. Unfortunately LuxCoreUI crashes on the larger scene I'm working on even with commas removed. I suspect this is entirely unrelated - it gets to "Camera clipping plane disabled" and quits to desktop.
Actually, it appears that commas are never used in the .SCN file - so any commas found can just be stripped out, no need for regex. Can anyone confirm that commas are never used in the .SCN? I confirmed that even in my rather complex scene, there are no commas other than the ones that match [0-9],[0-9]{3} so assume those are all ones that need to be stripped out.
Do I need to check the .CFG or .PLY files for commas as well? The default scene does not have any, and the .CFG doesn't seem to have anything that would be prone to getting a comma. However, larger .PLY files do end up with commas (eg in the vertex count). Not sure if these need to be stripped out (or if it's even useful to do so, since the PLY also has a bunch of binary data beyond the header that I can't read).
Re: PyLuxCore Tool Error ( v2.4, all scenes)
One more piece of info, hoping it helps finding a workaround.
The Interface-->Translation preference was slightly different in Blender 2.82: it was disabled by default (and was disabled in my previous test).
Enabling it as in the attached picture produces the same exact behaviour as the more recent Blender versions, no matter if language is set to "Automatic" or "English".
In the latest versions this setting is gone, translation is always enabled.
