Starting from the active object, all objects within the collection will be renamed, as well as the collection and the "BlockSurface" object. These objects will be renamed when creating a new "BlockSurface" object and when creating a new branch, using a pop-up that will automatically appear when creating them.
To rename the objects, follow these steps:
Select an object that belongs to a branch.
Modify the name of the character it belongs to, or just the name of the branch.
Press the "Rename" or "Ok" button in the pop-up menu to rename the objects.
