When exporting it always saves as .glb no matter how I configure settings, and unable to find the .bin.

Only currently selected UV set is exported.

Can't load the plugin in Maya 2019. I get this error when I try:
// Error: file: C:/Program Files/Autodesk/Maya2019/scripts/others/pluginWin.mel line 289: (glTFExport) // // Warning: file: C:/Program Files/Autodesk/Maya2019/scripts/others/pluginWin.mel line 289: No initializePlugin() or initializePlugin2() function

If I use the plugin, it generates a file with either nothing in it or won't view. I tried using the cmd line...
import glTFExport
glTFExport.export(r"D:\Downloads\ZSU_Substance\ZSU_Substance\BellHeli_cmd.gltf", resource_format='bin', anim='keyed', vflip=True)
but I get this...

Hello,

Im probably doing something wrong, but I cant get anything to export with any trans values. Any help would be much appreciated.

Hi @matiascodesal — Thanks for posting this plugin, it's awesome to see work toward glTF support in Maya. Quick question: have you seen https://github.com/Ziriax/Maya2glTF, which looks to me like a similar effort? I'm wondering if there are important differences between these (C++ vs Python would be one I imagine).

the last blendshape weight[354] was not in original maya blendshapes, but when imported to unity, it's there

This is the error I get every time i try to load the plugin.

// Error: file: /Applications/Autodesk/mayaLT2020/Maya.app/Contents/scripts/others/pluginWin.mel line 317: Plug-in, "/Users/Shared/Autodesk/maya/2020LT/plug-ins/glTFExport.py", was not found on MAYA_PLUG_IN_PATH. //

Hello, I'm having an issue not being able to export out of Maya. This is the error I'm getting:

// Error: line 0: IndexError: file C:/Users/Brandon/Documents/maya/2018/scripts\glTFExport.py line 397: list index out of range //
// Error: line 0: Could not save file "C:/Users/Brandon/Desktop/anmRig_combined.glb". //

Any idea why I'm getting this error?

Thanks!
Brandon

export works fine, but import crashes maya 2022.
also i want to notice there's no gltf extension filter when importing.
is import not provided?

I'm very new to Maya - have just installed a trial of the current version from the website, in MacOS Big Sur. Following the instructions in the readme, I get an error No module named 'glTFExport'

PluginManager;

I thought it might help to restart Maya, but it didn't.

In glTF meshes can have multiple primitives and each primitive can have a material. This allows for multiple materials per mesh.

I have simple model files with materials attached to it. Tried exporting it to glb files but got the following errors

// Error: line 0: RuntimeError: file /Library/Preferences/Autodesk/maya/scripts/glTFExport.py line 434: (kInvalidParameter): No element at given index // // Error: line 0: Could not save file

glTFTranslator.py is not showing up in plugin manager.
I placed everything in right directory but still this is not working...

Windows10, Maya2017

// Error: line 0: RuntimeError: file C:\Users/sidch/Documents/maya/2023/scripts\glTFExport.py line 438: (kInvalidParameter): No element at given index

Hi I was wondering if is possible to export multiple materials on the same mesh. When I try to export it is only using one material.

On Maya 2020, followed all of the steps for the GLTF Export, went into windows and loaded it, when I go export and save it says this:

// Error: line 0: RuntimeError: file C:/Users/Name/Documents/maya/2020/scripts\glTFExport.py line 438: (kInvalidParameter): No element at given index //
// Error: line 0: Could not save file "C:/Users/Name/Desktop/Random Shit/meebit/8-27/VOID.glb". //

This plugin makes excessive consumption of RAM, I tested in Maya 2019.2 on Mac and a PC and has the same problem, and basically it is processed when exporting ....... In the end I see this error ...

Failed to write file information

// Error: line 0: MemoryError: file H: / WS / My Documents / maya / 2019 / scripts \ glTFExport.py line 474: //

Hello

I have tried the latest version of this plugin and noticed that when the scene to be exported using the plugin is complex, it returns // Error: line 0: Could not save file whether the models have external links or not. When the scene is simple enough, it can export in glTF format, but all of the material properties are lost regardless of export settings.

Any idea how the material properties can be kept after exporting?

Could we make it compatible with the latest version of Maya?
// Warning: file: /Applications/Autodesk/maya2018/Maya.app/Contents/scripts/others/pluginWin.mel line 909: No initializePlugin() or initializePlugin2() function // // Error: file: /Applications/Autodesk/maya2018/Maya.app/Contents/scripts/others/pluginWin.mel line 909: (glTFExport)

The name of the materials are all (0)Unamed Material.. (1)Unamed Material... in the GLTF file. That's when looking at the model using Model viewer(https://modelviewer.dev/editor/). I'm using Maya 2019.

Heya! I get this message when trying to export all from Maya 2022: # Failed to write file information
// Error: line 0: RuntimeError: file C:/Users/MajesticLog/OneDrive/Documents/maya/2022/scripts\glTFExport.py line 438: (kInvalidParameter): No element at given index //
