  -p, --pretty-print      prefix all object names in output file

Current Limitations

No animation support
Only Lambert and Phong materials are supported

Some light properties are not converted correctly
Some material properties are not converted correctly
Textures must be put in asset’s folder, and use relative path in the material

Dependencies

FBX SDK

Requires Autodesk FBX SDK Python 2013.3 bindings.

You can download the python bindings from the Autodesk website: 
  http://usa.autodesk.com/fbx/

Don't forget the visit the FBX SDK documentation website:
  http://docs.autodesk.com/FBX/2013/ENU/FBX-SDK-Documentation/cpp_ref/index.html

Note: If you use the OSX installer, it will install the Python packages into the following folder.

/Applications/Autodesk/FBX Python SDK/[VERSION]/lib/

If the tool still can’t find the FBX SDK, you may need to copy the fbx.so, FbxCommon.py and sip.so files into your site_packages folder.

If you don’t know your site_packages folder, run python from shell and paste this:

import site; site.getsitepackages()

Python

Requires Python 2.6, 2.7 or 3.1 (The FBX SDK requires one of these versions)

sudo apt-get install build-essential
wget http://www.python.org/ftp/python/2.6.8/Python-2.6.8.tar.bz2
tar jxf ./Python-2.6.8.tar.bz2
cd ./Python-2.6.8
./configure --prefix=/opt/python2.6.8 && make && make install

实际使用时我碰到的问题

找不到FBX SDK

这个错误郁闷了我好久，下载了数个版本的python和fbx sdk 依然没有得到解决
很多版本的fbx sdk

就在刚刚，我突然发现自己翻了个很坑的错误，我下载的python到底是什么版本的？

我也不清楚呀，我记得就是官网上随便下载了个windows 平台的安装包而已……
于是问题就明确了，我一直以为我用的是64位版本的python，但实际上我下载的几个都是32位版本的。

描述下配置方法吧

安装python ，根据readme的建议，我们可以选择2.6，2.7，3.1。
选择FBX SDK 要与自己的python 版本相一致（我这里使用的是2.7版本的python 和2015.1的FBX SDK）
打开FBX SDK的安装目录，…\Autodesk\FBX\FBX Python SDK\2015.1\lib 将自己对应版的的文件夹内的内容复制出来，我这里需要复制的是Python27_x86 文件夹内的内容
打开你的python 目录，找到site-packages文件夹例 …\Python27\Lib\site-packages , 然后将刚才的三个文件复制在这里
测试下fbx sdk 配置是否已经成功
可以运行 Autodesk\FBX\FBX Python SDK\2015.1\samples 目录下的一些例子py文件进行测试，如果不报错，则表示FBX SDK配置成功

小贴士

打开cmd 一点点输入路径太慢了，可以先输入python 然后用鼠标点住将文件拖拽到cmd窗口上，文件的路径就会直接打在上面，挺方便的。
