Maya Animation Exporter

The Maya Animation Exporter is a Python script for Autodesk Maya that simplifies exporting skeletal animations to Unreal Engine in FBX format. It provides a user-friendly interface to select the output path, root joint, and up-axis, ensuring your animations are exported with Unreal-compatible settings. This script eliminates repetitive manual setups, saves time, and reduces errors in your animation pipeline.

Why You Need It

Manually exporting animations from Maya to Unreal Engine can be tedious and error-prone. You often deal with mismatched settings, unwanted geometry, or incorrect axis alignments. This script automates the process, letting you focus on creating great animations. It’s built for technical artists and riggers who need consistent, reliable exports in game development workflows.

Key Features

• Intuitive UI : Easily set output path, root joint, and up-axis (Y or Z) for your project.
• Automated FBX Settings : Applies Unreal-optimized settings, including baked animations and frame range detection.
• Selective Export : Exports only the skeletal hierarchy and animation, excluding unnecessary elements like skins or cameras.
• Error Prevention : Validates root joint and hierarchy to avoid common export issues.
• Time-Saving : Streamlines batch exports with consistent settings across multiple animations.
• Cross-Platform : Works on Windows, macOS, and Linux with Maya 2018 or later.

Installation and Usage

1. Install :
   • Copy main.py to your Maya scripts directory.
   • Alternatively, load and run it directly in Maya’s Script Editor.
2. Run the Script :

   exec(open('path/to/main.py').read())

3. Configure Export :
   • Output Path: Click "Browse" to choose where to save the FBX file.
   • Root Joint: Select the root joint in the viewport and click "Set," or enter its name manually.
   • Up Axis: Choose Y or Z based on your project’s requirements.
4. Export :
   • Click "EXPORT ANIMATION" to generate an Unreal-ready FBX file.
   • The script handles joint selection, FBX settings, and export automatically.

Recommended Workflow

• Set your timeline to the desired frame range.
• Ensure your rig has a properly structured skeleton.
• Select the root joint, run the script, and configure settings.
• Export and test the animation in Unreal Engine.

Who It’s For

• Riggers : Perfect for those managing complex skeletal animations.
• Technical Directors (TDs) : Ideal for streamlining animation pipelines in game development.
• Game Studios : Great for teams needing consistent, error-free animation exports.

Notes

• Always save your scene before exporting, as the script temporarily unparents the root joint.
• Check the script’s built-in validations to catch setup errors early.
• For troubleshooting, refer to the included error messages for guidance.
