LuxCoreRender Standalone CPU?

[matsbtegner]

Try to set your locale to US, your system seems to expect a "," instead of "." as decimal separator (and ignore luxcoreui request for a "C" locale). Have you compiled luxcoreui on your own or are you using a daily build?

I am using the latest February 11th build from GitHub both the Blender Addon and LuxCore Stand-alone.

There is an inconsistency in your directories: "/home/mats/LuxCore" Vs. "/home/mats/Programming/LuxCore"

/home/mats/LuxCore/ contains the compiled LuxCoreUI binaries.
/home/mats/Programming/LuxCore contains the source-code.
I copied all the scenes from the source directory to the directory containing the binaries but the results are the same. I will try to rebuild the scenes in Blender. Thanks for your help so far.

/home/mats/LuxCore/ contains the compiled LuxCoreUI binaries.
/home/mats/Programming/LuxCore contains the source-code.

And it is wrong, there is no "scenes/classroom/chair.ply" file under "." or "/home/mats/Programming/LuxCore/scenes/classroom" directory. There should be a single "LuxCore" directory, not 2 ("/home/mats/LuxCore" and "/home/mats/Programming/LuxCore").

Setting the locale to en_US solves the parsing issue.
