I am trying to use the new Groom Exporter Tool in Maya 2025.3
Here is an overview of my Groom Export window.
When I try running the tool with these grooms selected, I get the following output:
C:\Program Files\Autodesk\Maya2025>"C:\Program Files\Autodesk\Maya2025\bin\mayapy" "C:\Program Files\Epic Games\MetaHumanForMaya\lib\mh_groom_exporter\1.0.2\mh_groom_exporter\export_proc.py" "C:\Users\CHRIST~1\AppData\Local\Temp\tmpdluubg7y\export_options.json"
Qt WebEngine seems to be initialized from a plugin. Please set Qt::AA_ShareOpenGLContexts using QCoreApplication::setAttribute and QSGRendererInterface::OpenGLRhi using QQuickWindow::setGraphicsApi before constructing QGuiApplication.
