Directory Structure
Installation Directory
MotionBuilder is available for 64-bit architectures. By default, MotionBuilder is installed in the following directory:
| Platform | Default Directory |
|---|---|
| Linux | /usr/autodesk/MotionBuilder<version> |
| Windows | C:\Program Files\Autodesk\MotionBuilder <version> |
This installation path will be referred to as [MotionBuilder] in the remainder of this topic to represent the path of your MotionBuilder installation directory.

Python Subdirectories
| Linux Path | Windows Path | Description |
|---|---|---|
| [MotionBuilder]/bin/config/Python | [MotionBuilder]\bin\config\Python | Contains Python modules used in MotionBuilder as well as keyboard configuration files. For more information on customizing keyboard shortcuts, see Managing Python Tools. |
| [MotionBuilder]/bin/config/Scripts | [MotionBuilder]\bin\config\Scripts | Sample Python scripts. |
| [MotionBuilder]/bin/linux_64/python/pyfbsdk.so | [MotionBuilder]\bin\x64\python\pyfbsdk.pyd | The pyfbsdk Python module, which encapsulates the majority of the MotionBuilder SDK Python functionality. |
| [MotionBuilder]/bin/config/Python/pyfbsdk_additions.py | [MotionBuilder]\bin\config\Python\pyfbsdk_additions.py | Contains Python code used to bridge functionality between the OpenReality C++ SDK and Python. It contains tool management functions and some UI creation helper classes. |
User Configuration Directory
Any user, regardless of whether or not they have administrative privileges, can customize MotionBuilder by editing the files in their own configuration directory. A user's configuration directory is created the first time the user launches MotionBuilder at the following location:
| Platform | Default Config Directory |
|---|---|
| Linux | /home/<username>/MB/<version>/config |
| Windows | C:\Users\<username>\Documents\MB\<version>\config |
This user configuration directory, which we will refer to as [config], allows each user to specify their own keyboard shortcuts, Python startup programs and scripts, character templates, and layouts. The [config] directory is created using the [MotionBuilder]/bin/config directory as a template.
Users can place Python scripts in the [config]/PythonStartup directory to have their scripts run when MotionBuilder starts up. For more information, see Running Python Scripts and Command Line Options.
