Linux Commandline Batch Export does not work, even in 1.4 release.

[chiefwhosm]

Material Maker version: 1.4 Release - 5th October 2025 release (and previous: https://github.com/RodZill4/material-maker/issues/804).

OS/device including version: Debian Bookworm & Debian Trixie (12 and 13).

Issue description/Steps to reproduce: When issuing the following command: ./material_maker.x86_64 –export-material –target "Unreal/Unreal Engine 5" -o "/path-to-export/out.png" "/path-to-ptex.ptex" The program loads the UI, and then loads the file as opposed to exporting a file via commandline arguments. No actual export takes place.

I have tried other targets such as "Blender" and also set the output path as just a folder, not a file and also tried with a new simple .ptex file created in the latest version to make sure no compatibility issues were in play. I have also tried the recommended double dashes (--) and leaving the output blank as suggested in #804 but the issue remains the same.

Going to File>Export and manually exporting does work, just the batch export via commandline.
