How the Multi/Sub-Object Material Is
Cr e at ed
The Multi/Sub-Object material is created in one of
three ways, depending on what m aterial is a lready
applied to the selected sub-objects:
• No material applied
If the selected faces have no material applied, a
new Multi/Sub-Object m aterial is created. The
dragged material becomes a sub-material in the
new m aterial. If material IDs already exist, they
are preserved.
• Exist ing materia l applied (ot her than
Multi/Sub-Object material)
A new Multi/Sub-Object materia l is created
and applied to the selected faces. The existing
material is moved into the Multi/Sub-Object
material and becomes the first sub-mater ia l.
Unselected faces get material ID #1, the selected
faces get m aterial ID #2, and the dragged
material becomes par t of the Multi/Sub-Object
material. Existing m aterial IDs are not
preserved.
• Multi/sub-object material applied
If the existing Multi/Sub-Object material is
already applied more than once in the scene,
the material is copied and the new copy is
applied to the selected faces.
If the Multi/Sub-Object material is only applied
once in the scene, then the existing material
is used. The dragged material is added to the
existing Multi/Sub-Object material.
If the dragged material already is a part of the
Mult i/Sub-Object m aterial, then the selected
faces receive the corresponding material ID
number. If the selected faces all have the same
material ID number, and no unselected faces
arealreadyusingthisnumber,thenthisnumber
is used and t he new material replaces the old
sub-material at this ID. Otherwise, a new
material ID number is assigned to the faces,

any existing material IDs are preser ved.
