990 Chapter 9: Surface Modeling
When you attach an object, the materials of the
two objects are combined i n the following way:
• If the objec t being attached does not have a
material assigned, it inherits the material of the
object it is being attached to.
• Likewise, if the object you’re attaching to
doesn’thaveamaterial,itinheritsthematerial
of the object b eing attached.
• If both objects have materials, the resulting new
material is a
multi/sub-object material (page
2–1403)
that encompasses the input mat erials.
A dialog appears offering three methods of
combining the objects’ materials and material
IDs. For more information, see

Attach remains active in all sub-object levels,
but always applies to objects.
Attach List—Lets you attach other objects in the
scene to the selected mesh. Click to display a Select
Objects dia log where you choose multiple objects
to attach.
Explode group
Explode—Breaks up the current object into
multiple elements or objects b ased on the angles
ofitsedges.ThisfunctionisavailableinObject
mode as well as all sub-object levels except Vertex
and Edge.
The angle threshold spinner, to the r ig ht of the
Explode button, lets you specify the angle b e tween
faces below which separation will not occur. For
example, all sides of a b ox are at 90-deg ree angles
to each other. If you set the spinner to 90 or above,
exploding the box changes nothing . However, at
any setting below 90, the sides all become separate
objects or elements.
