Inheritance
Layers can have colors, just as geometry can. If a layer has a material, all its children in the selection tree
inherit this material, until one of the children is assigned its own material, at which point, all its children in
the selection tree inherit this material, and so on.
If you drag-and-drop materials onto layers, this works fine because only the layer picks up the material
and although its children inherit the material, they do not have it explicitly assigned to them.
Therefore, right-clicking on such a child will not allow you to remove the material because one was not
explicitly assigned in the first place.
However, if you use a rule to assign a material to a certain color, then all objects in the scene will get this
material explicitly assigned to them, including parent layers and child objects. If, with a selection
resolution of something like Geometry (which is more specific than a resolution of Layer), you right-click
a child object and click Remove Materials on the shortcut menu, then the material will be removed from
the child object, but not from the parent layer and there won't be any apparent difference.
To remove the material, you will therefore have to remove it from the parent object, in the above situation
this would be the layer.
Organizing and Managing Materials
In this section you will learn how to organize materials into folders, and how to manage the material
palettes.
Custom Folders
You can organize materials into custom folders for easy reference and management. By doing this, you
are, effectively, customizing a user archive.
To add a custom folder:
1. Open the Presenter window, and click the Materials tab.
2. Right-click the My Materials folder on the left pane, and click New Directory on the shortcut menu.
3. Expand the My Materials folder, right-click the new folder, and click Rename on the shortcut menu.
4. Type in the new name, for example 'GGK Project'.
To delete a custom folder:
1. In the Presenter window, Materials tab, expand the My Materials folder on the left pane, and
right-click the folder you want to delete.
2. Click Delete on the shortcut menu.
