page 5949 help topics. Changes you make to the Scene Event Render Options
affect the Render Scene dialog, as well.
Scene Motion Blur Turns on the scene motion-blur on page 7919 effect for
the whole scene. This is different from
object motion blur on page 7867 , which
creates motion blur for individual objects in the scene.
Scenes created with previous versions of 3ds Max that use both Object Motion
Blur and Scene Motion Blur may not render correctly, due to changes to Object
Motion Blur. Execute some test frames and adjust your blur settings if needed.
When you render with Scene Motion Blur activated, the Render Progress dialog
tells you which subsample is being rendered. The information appears in
parentheses to the right of the "Rendering Image" text. For example:
Duration Sets the virtual shutter speed for motion blur. When it's set to 1.0,
the virtual shutter is open for the entire duration between one frame and the
next. When it's set to a smaller number (for example, 0.25), the number of
subdivisions specified in the Duration Subdivision field will be rendered within
the specified portion of the frame (in this example, in the first .25 of the
duration between one frame and the next).
Duration Subdivision Determines how many sub-frame slices are rendered
within the Duration. The default is 2 slices, but you'll want at least 5 or 6 to
get a decent effect.
Dither % Sets the amount of
dithering on page 7760 between blurred pixels
of overlapping frame slices. If Dither % is set to 0, no dithering occurs.
Scene Range group
Scene Start/End Sets the range of scene frames to be rendered.
Lock Range Bar to Scene Range Becomes available when you deselect Lock
To Video Post Range. When it's available, the End spinner is disabled and
locked to the Video Post range. When you change the Start spinner it
automatically updates the End spinner based on the Video Post range set for
this event.
If you turn off Lock Range Bar To Scene Range, you can change either Start
or End spinners to whatever you want. This allows you to keep your scene
range locked to its native length, and still provides flexibility for mapping an
arbitrary scene range to an arbitrary Video Post range.
Lock to Video Post Range Renders the same range of scene frames as Video
Post frames. You can set the Video Post range in the Execute Video Post dialog.
