4. If you have items selected in the main navigation window or selection tree, then you can choose
choose Remove from selected items from the context menu to remove that material from only
those items you have selected in the scene.
Note
Deleting the material from the palette will automatically remove that material from any items in the
scene which it was applied to.
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
on a child object and choose Remove Materials from the context 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.
25.4. Managing Materials
The palette is where you edit and manage your materials for your scene. Materials are taken from the
archives into the palette where they are edited. You can then save the palette into a JetStream Palette file
(.nwp) for use in other scenes too.
Managing Palette Materials
1. Right click on a material in the right hand pane of the Materials tab (the palette).
2. Click Delete to delete the material from the palette. This will also remove the material from all items
in the scene.
3. Click Copy to copy the material to the clipboard. Right click on an empty space in the palette and
choose Paste to paste a copy of the material with a the same name suffixed with the next number in
the list. This process is useful if you want to test small tweaks to a material.
4. Click Rename to rename the material. You can also select the material and press F2 to rename it.
5. Click Regenerate Image to regenerate the thumbnail of the material in the palette with the current
attributes.
