MotionBuilder SDK Requirements

The MotionBuilder SDK requires that the Autodesk MotionBuilder software be installed on your computer.

CMake version 3.19 or above is required.

To develop additional user-interface elements with a C++ plug-in, you must install Qt 6.5.3.

To ensure that all OpenRealitySDK samples build cleanly, you will need to set the QTDIR environment variable to point to the Qt installation root folder.

Binary compatibility of your C++ plugins across different versions of MotionBuilder is not guaranteed. It is recommended that you recompile your C++ plugins according to the targeted version of MotionBuilder.

Windows Requirements

Visual Studio 2022 is required. The "Desktop development with C++" and "C++ CMake tools for Windows" Visual Studio components must also be installed.

Linux Requirements

gcc-toolset-11 and Ninja build are required.

Python Requirements

MotionBuilder 2026 supports Python 3.11.9. Your Python programs must be compatible with this version of Python.
