Combustion Map 1649
Oper ator —
Switches control to Combustion, where
you can select an operator. The results of the
operator appear as the image in the Combustion
map. The operator does not have to be the last
operator in the pipe.
While C ombustion is ac tive, you can also adjust
the operator. The Combustion map updates to
show the results.
Unwra p S elected—Take s t h e c u r re nt U V W
mapping coordinates of the currently selected 3D
object(orthecurrentFacesub-objectselection),
and displays them in Combustion. This can help
you coordinate the map and the mesh as you
paint. Th e Unwrap display is only an overlay. It is

UV List—Changesthemappingcoordinatesystem
(the d irection in which the map is projected) from
UV to VW or UW. UV projects onto the surface
of geometry like a slide projector. VW and WU

most useful choice.
UV —Specifies which mapping channel to un wrap
and paint. Range=1 to 99.
Tra ck Time—Links the Timeline in Combustion to
the time slider in 3ds Max. When Track Time is
enabled, you can use the t ime slider in 3ds Max to
navigatebetweenframesinCombustion.
Note: This control is not bidirectional; changing
the frame in Combustion does not change the
frame in 3ds Max.
Pai nt—When enabled, displays a p aint cursor in
3ds Max viewpor ts. You can then paint directly
onthe3Dgeometry.Draggingthecursorinthe
viewport over the geometry in 3ds Max creates
paint strokes inside C ombustion.
Co nstrai n To UV—When enabled, constrains paint
strokestoremainwithintheedgesoftheUV
mapping coordinates. When paint strokes are
unconstrained on an object such as a box, they
can jump to the other side of the map when you
cross a map’s edge. This can give erratic results. To
prevent this, enable Constrain To UV.

has a singularity (where the edges of the map
conv erge to a single point).
Selected Faces—Constrains the Combustion image
to only the faces selected. This gives additional
control or masking based on faces rather than UV
mapping.
