LightMap Shader Rollout 1423
Shader-specific rollouts
TherolloutsthatappearbelowtheDirectX9
Shader rollout and above the Software Rendering
rollout are the interface to the shader you chose.
These rollouts are specific to each shader.
Softw are Rendering rollout
Specifies a material that controls software shading
and rendering of objects to which the Direc tX 9
Shader material is applied. Viewports use DX9
shading unless the Software or OpenGL driver is
active. Renderings
always
usesoftwareshading.
U sually you will want to choose a material that
clearly identifies which objects in your scene have
the DirectX 9 Shader material applied.
Note: The DirectX 9 Shader material has no specific
settings for software shading. Any type of 3ds Max
material will do. Scenes from previous versions
that used DX9-specific sett ings are assigned a
Standard material with equivalent rendering
properties.
Note: If DirectX 9 is not available on your system,
but you assign the D irectX 9 Shader material
anyway (by using the Material/Map Browser’s
Incompatible option), this is the only rollout that
appears in the M aterial Editor.

When you have chosen LightMap as the
DirectX
viewport shader (page 2–1308)
,thisrollout
appears. The LightMap shader can display both a
base texture and a lighting map. Typically both

rendering to textures
(texture bak ing) (page 3–139)
Thebasetexture
typically would be a completed map, a blend map,
or a diffuse map. You can choose these map types,
as well as lighting map, to render as
elements of a
baked texture (page 3–142)
.
Note: In order to use the LightMap shader, you
must have 3ds Max configured to use the Direct3D
graphics driver. To change the g r aphics driver
configuration, r ef er to the
