different playback speeds are also useful when using the Motion Capture utility
on page 3798.
Active Viewport Only: Animation plays only in the active viewport. Turn this
off and the animation will play in all four viewports at once.
Speed: Choose one of these options to multiply the frame rate by the selected
speed.
Direction: When Real Time is off you have the option to change the direction
of the animation playback. Choosing Reverse will play the animation from
end to start. Choosing Pingpong will play the animation from start to end,
and then end to start.
Loop: When Loop is turned off, the animation will play once and stop.
Viewport Playback Speed
The ability of the program to play your animation at a specified rate depends
on many things, including the complexity of the scene, the number of objects
moving in the scene, the geometry display mode, and so on. The worst case
is a camera move in shaded mode, in which the viewport is filled with detailed
geometry. In such cases, it’s best to simplify the viewport display, using either
wireframe display or, in extreme cases, box display mode.
Naturally, it takes more computing power to display your animation in four
viewports, and playback smoothness is reduced. When Active Viewport Only
is on, you can switch active viewports during playback either by clicking the
label of an inactive viewport, or by right-clicking in an inactive viewport.
Working with Controllers
Everything you animate in 3ds Max is handled by a controller. A controller
is a plug-in that handles the storage and interpolation of all animated values.
The default controllers are:
■ Position: Position XYZ
■ Rotation: Euler XYZ
■ Scale: Bezier Scale
