Javascript Support QtWebEngine in Autodesk Maya 2025

[RawKeeX3D]

Qt Community,

Is it possible for a user to update the javascript implementation for an existing QtWebEngine implementation to a more recent version javascript? Or does anyone have a suggestion for a workaround based on the explanation of my problem below?

I'm porting an Autodesk Maya plugin from C++ to one based on the Maya Python 2.0 API for the purpose of exporting Maya content to the X3D file format (Web3D.org). The Python port is based on C++ code found here (links shown below to prove that the code exists):

• Previous 2008 C++ Release - https://rawkee.sourceforge.net
• Updated 2024 C++ Release - https://github.com/und-dream-lab/rawkee/

In the C++ version I implemented a GUI that allowed users to prep the scene for X3D animation, HAnim, and other X3D interactivity, which I called the Interaction Editor (IE). However, much progress has been made with cross-platform X3D scene editing since I originally created the X3D exporter for Maya. Specifically, there is a web-based product called X_ITE/Sunrize that would make the IE obsolete if I could implement it within Maya using Qt WebEngine.

• X_ITE - https://create3000.github.io/x_ite/
• Sunrize - https://create3000.github.io/sunrize/

However, it appears that Maya 2025's implementation of Qt via PySide 6 seems to be Qt 6.5.3, which I think uses Chrome 108 for the Qt WebEngine web browser. Unfortunately, X_ITE appears to be developed using Javascript functions [ specifically toSplice(), but probably others as well ] that requires ECMA 2023 functionality, which Chrome 108 doesn't support.

Anyone have any ideas how I can work around this issue?

Thanks,

Aaron

UPDATE: After blowing up Maya 2025 by doing a pip update on mayapy for Pyside6 and all of it's subcomponents (don't do that), I communicated with the X_ITE developers. They were able to release a version of X_ITE for me that removed the ECMAScript 2023 functions, and now uses javascript that is compatible with Chrome 108 and the version of PySide6/Qt6 compatible with QWebEngine in Maya 2025.
