Time group

ThesecontrolsrelateframesintheCombustion

workspace to frames in the Combustion map. See

the controls under "End Condition Group" for

how to hand le the map when it contains fewer

frames than the 3ds Max scene.

Start Frame—Determines which frame of the

Combustion sequence is used as the first frame of

the Combustion map in 3ds Max.

Durati on—Setshowmanyframesofthe

Combustion file sequence are used by the

Combustion map in 3ds Max.

Filtering group

These controls determine the method for

calculating

antialiasing (page 3–1001)

Pyramidal—Sets the default antialiasing method.

This method is faster than Summed Area filtering.

Summed Area—Implements a better method of

antialiasing. Summed Area filtering uses more

memory than Pyramidal. If it has to use virtua l

memory, it can dramatically increase rendering

time.

None—Performs no antialiasing. This option

takes the least time to render, but yields the lowest

quality results.

End Condition group

These controls define what the 3ds Max renderer

should do when the duration of the Combustion

project (or the range of frames used in the

Combustion map) is shorter than the rendering

sequence in 3ds Max.

Loop—Plays the Combustion project animation

repeatedly until the rendering sequence ends.

Ping Pong—Plays the animation forward, then

backward, and repeatedly plays forward and

backward until the rendering sequence is

completed.

Hold—Plays the animation once, then repeatedly

displaysthelastframeoftheprojectuntilthe

rendering sequence is completed.

Gradient maps used for the stoplight lamps, and for the

background of the scene

Gradients shade from one color to another. You

specify two or three colors for the gradient;

the software interpolates i ntermediate values.

Gradient maps are 2D maps.

Tip: You can swap colors by dragging one color

swatch over another, then clicking Swap in the

Copy or Swap Colors dialog. To reverse the overall

direction of the gradient, swap the first and third

colors.
