This script has several functions and operators, grouped for convenience:
|
||||
|
||||
* assign material:
|
||||
offers the user a list of ALL the materials in the blend file and an
|
||||
additional "new" entry the chosen material will be assigned to all the
|
||||
selected objects in object mode.
|
||||
|
||||
in edit mode the selected polygons get the selected material applied.
|
||||
|
||||
if the user chose "new" the new material can be renamed using the
|
||||
"last operator" section of the toolbox.
|
||||
|
||||
|
||||
* select by material
|
||||
in object mode this offers the user a menu of all materials in the blend
|
||||
file any objects using the selected material will become selected, any
|
||||
objects without the material will be removed from selection.
|
||||
|
||||
in edit mode: the menu offers only the materials attached to the current
|
||||
object. It will select the polygons that use the material and deselect those
|
||||
that do not.
|
||||
|
||||
* clean material slots
|
||||
for all selected objects any empty material slots or material slots with
|
||||
materials that are not used by the mesh polygons or splines will be removed.
|
||||
|
||||
* remove material slots
|
||||
removes all material slots of the active (or selected) object(s).
|
||||
|
||||
* replace materials
|
||||
lets your replace one material by another. Optionally for all objects in
|
||||
the blend, otherwise for selected editable objects only. An additional
|
||||
option allows you to update object selection, to indicate which objects
|
||||
were affected and which not.
|
||||
|
||||
* set fake user
|
||||
enable/disable fake user for materials. You can chose for which materials
|
||||
it shall be set, materials of active / selected / objects in current scene
|
||||
or used / unused / all materials.
