2D Mapping Coordinates
Like any 2D map in 3ds Max, mapping coordinates
control how a Combustion map is positioned on
objects.
For geometric primitives, mapping coordinates
are usually provided automatically. For some
kinds of geometr y, such as
meshes (page 1–984) ,
patches (page 1–980) ,and NURBS surfaces (page
1–1079)
,youmustapplya UVW Map modifier
(page 1–905)
to provide mapping coordinates.
Cont rols in a
2D map’s Coordinates rollout (page
2–1434)
affect how the map is positioned.
When you work with a Combustion map, these are
the important p oints to remember:
• When you apply a Combustion map to an
object, leave mapping set to the default values
of Texture and Explicit Map Channel.
• When you use a Combustion map as an
environment map, set mapping to Environ
and then choose the mapping shape from the
Mapping drop-down list.
• The offset, tiling, mirror, and angle controls are
useful especia lly w hen the size of the projected
Combustion map is smaller than the geometry.
• You can choose between UV, VW, and WU
projections. (You can also do this from the
Combustion Parameters rollout, as described
below.) UV projects onto the surface of
geometry like a slide projector. VW and WU

With a Combustion map, UV is almost always
the most useful choice.
Combustion Parameters rollout
The Combustion Parameters rollout appears when
you a ssign a Combustion map to a material.
Project—Loads the file to use in Combustion. You
canloadonlyfiletypessupportedbyAutodesk
Combustion, such as Combustion workspace files
(
cws), or footage and image file formats supported
by Combustion (see the
Combustion User’s Guide
for information on supported footage formats).
Edit—Launches Combustion from the 3ds Max
Material Editor. If a project is loaded, it is
opened in Combustion. If no project is loaded,
Combustion displays the New dialog. This dialog
lets you specify a project type, name, video format,
duration, and background color.

These controls affect how you use Combustion
with 3ds Max.
