Rendering Options group
The options in this group let you choose whether
to include shadows, texture maps, or a radiosity
solution in vertex colors.
Note: You can save a radiosity solut ion in
vertex colors, but not

illumination, which is not stored in the scene’s
geometry.
Shadows—When on, shadows are used when the
vertices are shaded. Default=off.
Tip: Youcansoftentheshadowedgebyusingthe
VertexPaint modifier’s Paint or Blur tools.
Mapping—When on, texture maps are used when
the vertices are shaded. Default=off.
The radio buttons specify how to use radiosity
data.
•
No R adiosi ty—(The default.) Do not use the
radiosity solution when assigning vertex colors.
Note: This opt ion is the only one available
unless a
radiosity solution (page 3–50) is
present in the scen e.
•
Ra diosity, Reuse Direct I llum. f rom
Solution—
Includes radiosity in the vertex color
assignments, and uses the direct illumination
from the solution.
This is comparable to the choice Re-Use Direct
Illumination F rom Radiosity Solution on the
Rendering Parameters rollout (page 3–70) .
This choice disables the Shadows toggle,
because shadows don’t need to be recomputed.
•
Ra diosity, R ender Direct Illumination—Includes
radiosity in the vertex color assignments,
but uses a separate pass to render direct
illuminat ion.
This is comparable to the choice Render Direct
Illumination on the
Rendering Parameters
rollout (page 3–70)
.
•
Ra diosity, Indirect Illum. Only—Includes only
indirect illumination from the radiosity
solution in the vertex color assignments.
This choice disables the Shadows toggle,
because shadows don’t need to be recomputed.

whether regat hering is enabled or disabled.
