How to batch export Unity3d prefab files to FBX format?

The solution that I found is a bit lengthy. I needed to convert prefab files to fbx format and then used blender to convert fbx files into wavefrontObj.To convert prefab files to fbx file format I used a Unity Package called FBX Exporter. The installation guide that I followed is from here.

After converting the files into fbx format I used blender to convert the files into obj format. I only needed the mesh files, so I excluded materials.To batch convert fbx files to wavefrontObj files I wrote the following script.

import bpyimport globfbx_file_folder = "input_folder/*.fbx"mylist = [f for f in glob.glob(fbx_file_folder)]for input_file in mylist:output_file = input_file.split(".")[0]output_file = output_file + ".obj"print(output_file)bpy.ops.wm.read_factory_settings(use_empty=True)bpy.ops.import_scene.fbx(filepath=input_file)bpy.ops.export_scene.obj(filepath=output_file,use_materials=False,check_existing=True)

To run the script, save the files as convertFBXtoOBJ.py and in terminal run the following command once blender is installed.

blender --python convertFBXtoOBJ.py

To get information about the API that I have used for the script, Blender PyDocs will be a great help.
