PMX2FBX mirror via Noesis (cause Blender is bad at fbx)

Imagine doing
-flipax 2
in Noesis.
Instead of
Whatever
blender is doing with
@echo off
set BLENDER_PATH="C:\portableapps\blender36\blender.exe"
set SCRIPT_PATH="%~dp0rotate_mirror_fbx.py"
REM Check if a file was dragged and dropped
if "%~1"=="" (
echo Please drag and drop an FBX file onto this script.
pause
exit /b
)
REM Get the input FBX file path
set INPUT_FBX="%~1"
REM Run Blender with the Python script and input file
%BLENDER_PATH% --background --python %SCRIPT_PATH% -- %INPUT_FBX%
echo.
echo Finished processing %INPUT_FBX%.
echo Output saved as %~dpn1_modified.fbx
pause
