object; when All Selected or All Prepared is chosen, the options apply to all
selected or prepared objects.
Object Level When on, projects from the object level of the high-resolution
object. Default=on.
■ Put to Baked Material (The default.) When chosen, the object-level
projection is rendered in the baked material.
Sub-Object Levels When on, uses the active sub-object selection, and makes
the Mapping Coordinates group > Sub-Objects controls available. Default=on.
■ Put to Baked Material When chosen, the sub-object level projection is
rendered in the baked material.
The following options apply to sub-object rendering, when only a portion of
the geometry is being rendered to the normal bump map:
■ Full Size (The default.) When chosen, the size of the normal bump map
is the same as if all geometry were being rendered.
■ Proportional When chosen, the size of the normal bump map is fitted
to the size of sub-object selection. The Proportional Multiplier on the
Projection modifier's Reference Geometry rollout on page 1560 can change
the default size of the proportional map.
For example, consider a plane that is 4 segments x 4 segments. Each "poly" in
the plane is a separate sub-object, for a total of 16 sub-objects. If the output
Map Size is 64, the object rendering output is 64 x 64 pixels. If Full Size is
chosen, each sub-object rendering is also 64 x 64 pixels. If Proportional is
chosen, each sub-object rendering is 16 x 16 pixels. If you change Proportional
Multiplier to 2.0 in the Projection modifier, each sub-object rendering is now
32 x 32 pixels.
Mapping Coordinates group
Object These controls are for basing the rendered texture on the object level
of the source object.
■ Use Existing Channel When chosen, unwrapping uses an existing map
channel.
■ Channel When Use Existing Channel is active, lets you choose the
channel to use for unwrapping.
