    Trying to generate lightmaps results in thousands of error messages like the ones in the small excerpt from the Editor.log below.
    Is there a way to get a more verbose log on these external processes?

    Code (CSharp):
    1. Failed executing external process for 'Light Transport' job.
    2. (Filename: /home/builduser/buildslave/unity/build/Editor/Src/JobManager/JobManager.cpp Line: 544)
    3.  
    4. Failed executing external process for 'Light Transport' job.
    5. (Filename: /home/builduser/buildslave/unity/build/Editor/Src/JobManager/JobManager.cpp Line: 544)
    6.  
    7. [00:31:17] Enlighten: Finished 775 Light Transport jobs (278,37s execute, 0,01s integrate, 248,98s wallclock)
    8. [00:31:18] Enlighten: Finished 1 Tetrahedralize Probes job (0,06s execute, 0,00s integrate, 0,31s wallclock)
    9. Failed executing external process for 'Create ProbeSet' job.
    10. (Filename: /home/builduser/buildslave/unity/build/Editor/Src/JobManager/JobManager.cpp Line: 544)
    11.  
    12. Failed executing external process for 'Create ProbeSet' job.

    This is the state after baking lightmaps for one terrain:

    Are you using Mono Bleeding Edge in your project? I discovered a bug in the upstream MBE that affects Linux yesterday afternoon that would cause this issue. If you are using the new Mono, you may want to consider switching back to regular Mono for now.

    (Note that this bug in MBE affects all versions of Unity to date.)

    Thanks, switching back to the stable worked and the error messages are gone. The baking is much faster now so that bug costs a considerable part of the process performance.

    I'd say a couple of weeks.
