This menu manages the Scene Materials group.
Click to update the list of materials and maps in the Scene Materials group.
This choice has no effect if Auto Update is on.
When on, 3ds Max automatically updates the list of materials and maps in the Scene Materials group. Default=on.
When on, the Scene Materials group shows only materials assigned to currently selected objects. (If no object is selected, or no selected object has a materal, the Scene Materials group appears empty.) When off, the Scene Materials group shows all materials used in the scene. Default=off.
The choices on this submenu specify which 3ds Max areas to inspect when updating the material/map list in the Scene Materials group. All three are on by default:
If you turn off one of these choices, the corresponding materials and maps (for example, maps used in the current Environment) no longer appear in the Scene Materials group. Turning a choice back on again displays the corresponding materials and maps once more.
When on, expands the group display to show all materials, sub-materials, and maps in the group. When off, shows only top-level materials. Default=off.
