CWS (Combustion Workspace) Files 611
Printing Density Adjustment—Represents the
transfer function from printing density (10-bit
log) to 16-bit linear with the white point mapped
to a maximum code value of 65535.
Conversion of logarithmic printing density to a
linear representation requires both a scaling and
an anti-log operation. With 16-bits linear, it is
possible to maintain the full printing density
range. The 90% white card at code va lue 685 is
mapped to maximum code value of 65535.
The Wh i te Pt and Black Pt spinners let you adjust
the90%whitecodeandthe2%blackcode.

from Autodesk. CWS is a resolution-independent,
vector/raster file format.
You can use CWS files in conjunction with the
Combustion map (page 2–1639).Youcan’tuse
aCWSfileasageneral-purposebitmap. You
can also generate a CWS file by using the Render
Elements option (page 3–130) when you render a
scene.
Impor tant: Only Combustion 2.1 and later formats are
supported. Maps in the Combustion 1 format are not
supported in 3ds Max.
DDS Files
The DirectDraw
®
Surface (DDS) file format is
used to store textures and cubic env ironment
maps,bothwithandwithoutmipmaplevels.This
format can store uncompressed and compressed
pixel formats, and is the preferred file format for
storing DXTn compressed data. Microsoft
®
is the
developer of this file format.
You can use DDS files as texture maps.
With Direct3D 9, you can render to the DDS
for mat. ( With DX8 or DX9, DDS files can be
rendered using the Metal Bump shader (page
2–1614),aswell.)Ifyoursystemdoesnotsupport
DX9, you c an use DDS files as textures, but you
can’t render them.
Interfa ce
Sur face/ Volume Format group
DDS supports a variety of output formats, which
vary in the number of pixels allocated to the red,
green, and blue (RGB) channels, to the optional
alpha channel (transparency), and to possible
unused bits. There is also a set of compressed
formats.
