When you have chosen LightMap as the DirectX
viewport shader (page 2–1464),thisrollout
appears. The LightMap shader can display both
a base texture and a lighting map. Typically
boththesemapscomefromrendering to textures
(texture baking) (page 3–144) Thebasetexture
typically would be a completed map, a blend map,
or a diffuse map. You can choose t hese map t ypes,
as well as lighting map, to render as elements of a
baked texture (page 3–146).
Note: In order to use the LightMap shader, you
must have 3ds Max configured to use the Direct3D
graphics driver. To change the graphics driver
configuration, refer to the Viewport Preferences
(page 3–821) topic.

rollout appears.
When you have chosen Metal Bump as the
DirectX viewpor t shader (page 2–1464),thisrollout
appears. The Metal Bump shader can display
avarietyoftexture-baked maps (page 3–144),
including normal map s for an embossed effect. It
is good for displaying shiny surfaces.
Note: In order to use the Metal Bump shader, you
must have 3ds Max configured to use the D irect3D
graphics driver. To change the gr aphics driver
configuration, refer to the Viewpor t Prefere nces
(page 3–821) topic.
The Metal Bump shader’s results are alway visible
in viewports, regardless of the object type.
Wa rn in g : The Metal Bump shader lets you adjust
settings to get various effects in shaded viewports.
These settings will not necessarily apply when you
display the texture-baked object on other Direct3D
devices.
