![]() But if we take the child out of the group, we break the relationship between the pyramid and the null and the pyramid's coordinates are converted to world space. ![]() So by moving the parent, we see that the child object's relative coordinates are unchanged. A child object's coordinates are relative to the parent. And if I move the null, once again, you can see that that value has not changed at all. Looking at the pyramid, for example, we don't see any change to the X coordinate. As we move this back, you can see the exposition change. And we'll switch over to the Coordinates tab. Let's just select our move tool and grab the null. And what's actually happening is the object properties will change. So we could grab our scale tool and scale up this null object. The child objects inherit the values of the parent. By grouping these objects in this null, we have made them children of the null object. A null is basically an object that doesn't render but it has an access. And Alt-G is a very useful keyboard shortcut to remember. We select them in the object manager here, come over to the object menu, and choose group objects. We can group objects by first selecting them. In the Basic tab, there's a section called Icon Settings and you can load in a preset. ![]() You can even change the visual representation of the null object to be a folder if you like. And nulls are very useful for keeping the object manager neat and organized. So it's important to note that in the object hierarchy, a child can also be a parent as can a peer. And this parent is still a parent because it has children but it's also a child. Now this is a really simple hierarchy and it can get a bit more complex if we take the parent and then Control or Command, click and drag. So the child and the peer will become children of the parent and because the child and peer are on the same level of hierarchy, they're both children, they're both peers. You can press the down arrow and jump to the next object. I'll create a few null objects to demonstrate this. And there are three main levels: parent, child, and peer or sibling. The object hierarchy is a crucial core concept to grasp. Cinema 4D scenes or projects are built by creating and combining objects in a hierarchy.
