The key bindings for the Qt3DExtras camera controllers are done in
QAbstractCameraController. There isn't a way to modify them through the
API. (e.g. See my previous email to the list about the escape key and this
bug report: https://bugreports.qt.io/browse/QTBUG-69802 )

I think the assimp library version changed between Qt versions. You might
try its viewer to see if it's an assimp problem:

I agree that is very frustrating. What I find even more frustrating is the
complete lack of useful documentation for the Qt3D module and the broken
examples. It's really not up to the standard of the other parts of Qt I've
worked with. I really, really want to work with it, but it's not making it
easy (or enjoyable) :-)
