GLTFMaya

A Maya plug-in for importing and exporting glTF 2.0 (.gltf) and glTF Binary (.glb) models and animations.

Supports Autodesk Maya 2019 through 2027 on Windows (x64).

Features

• Import glTF and GLB models and animations into Maya
• Export glTF and GLB models and animations from Maya

Installation

1. Go to the Releases page and download the zip that matches your Maya version (e.g. GLTFMaya-Maya2024-Release.zip).

2. Extract the zip. Inside you will find GLTFMaya.mll.

3. Copy GLTFMaya.mll into Maya's plug-in folder:

   • C:\Program Files\Autodesk\Maya<version>\bin\plug-ins\

   Replace <version> with your Maya version, e.g. 2024.

Loading the plug-in

1. Start Maya.
2. Open Windows -> Settings/Preferences -> Plug-in Manager.
3. Find GLTFMaya.mll in the list.
4. Tick Loaded to load it for this session. Tick Auto load if you want it to load every time Maya starts.

If the plug-in loaded correctly you will see [GLTFMaya] loaded. in Maya's script editor output.

Importing a model or animation

1. Go to File -> Import...
2. In the Files of type dropdown, choose glTF or glTF Binary.
3. Select your .gltf or .glb file and click Import.

Or.. just drag it into your scene.

Exporting a model or animation

1. In the viewport or Outliner, select the objects you want to export.
2. Go to File -> Export Selection...
3. In the Files of type dropdown, choose glTF or glTF Binary.
4. In the export options on the right side of the dialog:
   • Leave Export Animation unticked to export the selected model geometry.
   • Tick Export Animation to sample the joint animation across the playback range.
5. Choose a filename and click Export Selection.

Supported Maya versions

Builds are published for Maya 2019, 2020, 2022, 2023, 2024, 2025, 2026, and 2027. Make sure you download the zip that matches the version of Maya you are running. A plug-in built for one Maya version will not load in another.

Troubleshooting

• The plug-in does not appear in the Plug-in Manager. Double-check that GLTFMaya.mll is in the plug-in folder listed above, then click Refresh in the Plug-in Manager.
• Maya says the plug-in failed to load. You are most likely using a build for a different Maya version. Download the zip that matches your Maya version.
• My format is not in the Import/Export dropdown. The plug-in is not loaded. Open the Plug-in Manager and tick Loaded next to GLTFMaya.mll.
• My problem isn't listed here! Create an issue on the issues page and I will get around to it.

Building from source

If you want to build the plug-in yourself instead of using a release:

1. Install Visual Studio 2022 with the Desktop development with C++ workload.
2. Download the Autodesk Maya devkit for your Maya version and extract it somewhere on disk.
3. Open GLTFMaya.sln in Visual Studio.
4. Set the MAYA_ROOT MSBuild property to the path of the extracted devkit (the folder that contains include\ and lib\).
5. Build the Release / x64 configuration. The output is bin\Release\GLTFMaya.mll.
