Can you explain a bit more detailed what you mean with "combine multiple objects together"? Do you want the objects to be locked together but being able to rotate independently or something? If you simply want to disable collisions between objects you can use https://doc.qt.io/qt-6/qml-qtquick3d-physics-physicsnode.html#filterGroup-prop

@dante I doubt that it will work readily with QML. Javascript support in QML is very restricted as compared to that of Web-Browsers. It lacks of certain objects which are mostly used in these web-browsers supported Javascripts. You can find more info here: http://doc.qt.io/qt-5/qtqml-javascript-hostenvironment.html http://doc.qt.io/qt-5/qtqml-javascript-expressions.html http://doc.qt.io/qt-5/qtqml-javascript-hostenvironment.html#javascript-environment-restrictions You will need to create you own port of it without those restrictions. For eg. here is a blog post for porting-three-js-code-to-canvas3d. Something similar will be needed for the rest too.
