have you installed Qt3D along with Qt? In Qt 6, it's not installed by default, in some versions you actually need to build it from source

Qt3D Studio is NOT the same as Qt3D

6.0.4 definitely had qt3d in source only, so would need to be compiled and installed. 6.1.3 has prebuilt qt3d in the "Qt/Qt 1.6.3/Additional Libraries" section of the Maintenance Tool

might need this patch. It's old though, may need updating https://codereview.qt-project.org/c/qt/qt3d/+/284268

I hitting this now. Any fix?

I'm afraid these examples are part of KDAB's training material and not publicly available
