This is a small Python script that can convert PAYDAY 2 normal maps to regular normal maps and vice versa.

Usage
Simply drag an image file onto one of the bat files, depending on which direction you want to convert.
You can also directly call the python script from the command line like this:

python convert_normal.py image.png to|from

If you want to convert from PAYDAY 2 normal to regular, use "from", use "to" for the opposite direction.

Additional notes

• You might need to install the Pillow library for Python if it's not included in your Python installation, you can do so with:
  pip install Pillow
