# The script exports multiple files from Blender into fbx models.
# It searches the path recursively and creates .fbx files next to the .blend files,
# then it renames corresponding Unity *.blend.meta files to *.fbx.meta to keep editor references,
# !!! then it deletes the .blend files !!!
# You need Blender to be installed on your machine.
# You need to specify the following command line arguments:
# Blender's directory, path to args-Unity-BlenderToFBX.py, input directory (with blend files)
