Proportion Multiplier—When Proportional is
chosen for sub-object normal bump mapping in
the Projection Mapping group of the Objects To
Bake rollout (page 3–158) for Render To Texture,
this value multiplies the default size of the normal
bump map. Range=0.0 to 2.0. Default=1.0.
For example, if Proportional rendering of a
sub-object were to render a sub-object select ion
at 16 x 16 pixels, changing Proportion Multiplier
to2.0wouldchangethesizeofthenormalbump
map to 32 x 32 pixels.
This control is unavailable unless a sub-object
selection is active.

Display Toggle group
The Display Toggle group is useful when you
want to compare the hi—res to your low-res
geometry. You can quickly toggle between your
low-res geometry and your hi-res geometry to
compare versions. You can show selected or a l l
hi-res geometry.
Enable—When on, makes it possible to show or
hide reference geometries. Default=off.

When Enabled is on, click Hide
Reference Geometry to hide your hi-res geometry.
Conversely, click Hide Working Ge ometry to hide
your low-res geometry. You can also selectively
show and hide high-res geometries in your Pick
List. Click Off
to hide a geometry. Click Hide
to show a geometry.

These settings adjust the cage and its display.
The cage is the nonrenderable geometry that the
Project ion modifier uses as the surface from w hich
it ray-traces normals.
Note: Special export/import functionality
available on this rollout lets you convert the cage
intostandardgeometryofthesametypeand
topologyasthecageandmodifiedobject,which
you can edit using standard methods and then use
to define a new shape for the cage. This provides
access to the f u l l range of mesh-editing tools
available in 3ds Max for shaping the cage to your
precise requirements. For example, with editable
poly, you can tak e advantage of tools such as
Loop,Ring,Grow,andShrink,andquicklyswitch
among sub-object levels such as Face and Vertex.
Procedure
To use Export and Import with a cage:
1.
Create a c age:
1. Create low-resolution and high-resolution
objects. In most cases, for best results they
should be arranged concentrically.
2. Apply the Projection modifier to the
low-resolution object.
This creates the cage with the same shape
and position as t he low-resolution object.
3. UsetheReferenceGeometryrolloutcontrols
to specify one or more high-resolution
objects.
4. On the C age rollout, click Update.
