Color
Adjusts the material’s three color attributes—main, ambient, and reflective.
The current color is shown in a color swatch at the bottom of the Color area,
as well as in the swatch next to the button that shows which color you’re
adjusting.
Bitmap Blend
Affects the degree to which a bitmap is used in rendering. A material can have
four different bitmaps specified for it: one each for the Color/Pattern,
Reflectivity, Transparency, and Bump Map rendering attributes.
For pattern and texture maps, the bitmap is blended with the material’s main
(diffuse) and ambient colors. Blend affects the amount of reflection or
transparency for those attributes and the degree of bumpiness for bump maps.
The Bitmap Blend value can range from 0 to 1.0. The default value is 0.0 when
no bitmap is specified, 1.0 when a bitmap is specified.
If the bitmap is not tiled, fixed-scale materials lock all bitmap placement
settings together for Pattern, Transparency, and Bump Map. The bitmap
placement setting for Pattern takes precedence if it is available. If no pattern
map is present, the settings for Transparency are used. If neither Pattern nor
Transparency is present, the settings for Bump Map are used.
NOTE The blend of an opacity map takes precedence over the value chosen for
Transparency.
File Name
Specifies a bitmap.
Preview
Displays the selected material as either a sphere or a cube.
Adjust Bitmap
Displays the Adjust Material Bitmap Placement Dialog Box, in which you can
specify the bitmap’s offset and scaling, or placement values.
Find File
Displays the Bitmap File dialog box (a standard file selection dialog box), in
which you can select a bitmap file.
NOTE When a material includes one or more bitmaps, you should set the mapping
coordinates for objects to which the material is attached. See SETUV. The Photo
