You can layer Booleans in the stack display, so that
a single object can incorporate many Booleans. By
navigating through the stack display, it’s possible
to revisit the components of each Boolean and
make changes to them.

Most primitives use several material IDs (page

ontheirsurfaces. Forexample,abox
uses material IDs 1–6 on its sides. If you assign a
Multi/Sub-Object material (page 2–1403) with six
sub-materials, 3ds Max assigns one to each side. If
you assign a multi/sub-object material with two
sub-materials, 3ds Max assigns the first material
to sides 1, 3, and 5, and the second goes to sides
2, 4, and 6.
When you create a B oolean from objects that have
materials assigned to them, 3ds Max combines the
