Category: (core) Scene (See list of specification categories)

Introduction: Describes a range of time for a scene and its time system.

Concepts

Working with animated sequences within the context of film, TV, or simulation often requires an overall scene start and end time, with a time system used for display purposes, which is chosen according to the context in which the animation is used.

Details

The end times should be greater than or equal to the start times.

The time system does not affect the internal representation of the time values used by modo, nor their textual representation in the COLLADA data; the time values are always specified in seconds.

modo 401 stores a per-scene up axis setting in an asset element within the visual scene, as shown in the example below.
