"Without a parent node except for the scene's root." What does this mean?

[DeadM4nn]

It says on the wiki that the PhantomCamera needs to be "Without a parent node except for the scene's root.".

The way I read this is that the phantom camera can be attached only to the root node?
This means I can't have a phantom camera anywhere else? i.e. instantiated scenes.

Because I have objects inn the 3D world I want the camera to look at, but these phantom cameras will not be sitting in the world's root node.

The short answer is that you can add the PCam basically wherever you want scene tree-wise.

The note in the documentation was to address a common issue with people adding a PCam as a child node of moving objects — often a CharacterBody node. Where issues or questions would regularly spring up about the camera moving in unexpected patterns due to the parent node moving on top of the movement logic of the PCam.

This is changing in the 0.8.1 release, where the scene tree placement of the PCam will automatically ignore any transform changes of its parent node(s), so the note will also be removed as a result.
