Removing Level of Detail models in a Three.js Group

My THREE.Group() contains numerous LODs and I need to remove all the objects within it. The group includes Lights, LensFlare, other Groups, Points, Lines, and Meshes totaling around 350 items.

systemGroup.traverse (function (obj){
    systemGroup.remove(obj);
});

While this code successfully removes 175 objects, I encountered an error:

Uncaught TypeError: Cannot read property 'traverse' of undefined

on the first line of my code example.

I also attempted

scene.remove(systemGroup);

This solution works, but new objects added to the group do not erase the previous ones. I want to completely clear the group to start fresh, both for performance reasons and because I frequently fill it with many objects.

Any help is greatly appreciated.

"Error: Cannot access property 'traverse' of undefined"

It seems like systemGroup has not been defined in the specific context you are trying to use it in.

Double-check where systemGroup is defined, the context from which you are attempting to call systemGroup.traverse, and ensure correct spelling or capitalization. If none of these solutions work, sharing your complete code may be necessary for a more accurate resolution.
