2D Mapping Coordinates
Like any 2D map in 3ds Max, mapping coordinat es
control how a Combustion map is positioned on
objects.
For geometric primitives, mapping coordinates are
usually provided automatically. For some kinds of
geometry, such as meshes (page 1–996), patches
(page 1–993),andNURBS surfaces (page 1–1078),
you must apply a UVW Map modifier (page 1–922)
to provide mapping coordinates.
Cont rols in a 2D map’s Coordinates rollout (page
2–1625) 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 especially when the size of the projected
Combustion map is smaller than the geometr y.
• You can choose between UV, VW, and W U
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 assign 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 Combust ion 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 dia log
lets you specif y a project ty pe, name, v ideo format,
duration, and background color.
