Hi @NolaDonato, could you comment in the code line where that inconsistency happens?

Because I am not setting the owner without adding the component to a scene object.

[NolaDonato]

From GVRComponentGroup:

public void addChildComponent(T child) { synchronized (mComponents) { mComponents.add(child); if (owner != null) { child.setOwnerObject(owner); } } } You are setting the owner of the child component to be the same as the component group. The component group has been added to the scene object. The child object has only been added to the component group, not the scene object. If you want the owner to be propagated FOR CONSTRAINTS, then put that code in GVRConstraint instead of putting it in a general place where it can cause unforeseen side effects.

I see your point, onAttach should happens when the component is attached to a scene object as you know but the Component group is forwarding the onAttach() to its children.

I don't would like to implement some "special" code in the components to handle group support.

I mean "special" code to Constraints, to Colliders, to spatial audio... we need some logic that works for all components
