Fla t M i r ror
Flat mirror map reflects the ice-cream shop’s interior.
If you want to create a flat, mirrored surface in a
scene, such as a highly polished floor, you must
use a flat mirror reflection map.
Flat m irror reflection maps must be assigned to
your geometry in a specific way, and work only
on flat surfaces.
When you u se flat-mirror reflection maps, keep
the following in mind:
The flat-mirror material must be assigned to
connected, coplanar faces on a flat surface of
the object. If your flat-mirror reflection doesn’t
work, it’s probably because non-coplanar faces
have been assigned the flat-mirror material. This
can happen during the select ion process, if one
or more non-coplanar faces are included in the
selection set. It c an a lso happen if you’ve already
assignedthesamematerialelsewhereontheobject
(coplanar faces are two or more adjacent faces that
are on the same two-dimensional plane, such as
the surface of a floor).
If you want to reflect in multiple planes of the same
object, detach each plane into a separate object
before you assign the material.
Flow
A par ticle system (page 3–1084) can contain any
number of separate part icle flows. Each flow
consists of an isolated chain or sequence of
events
