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.
Attributes
Name Type Description Required?
sid xs:ncname A unique symbol within the technique; one for each value. Yes
name xs:ncname A user-friendly name for the param. No

Child Elements
sid name Description type Default Occurrences Named values
currentS Scene_Current_Start_Time Current start time of the scene. float 0 0 or 1
currentE Scene_Current_End_Time Current end time of the scene. float 5 0 or 1
fps Scene_FPS Number of frames per second. float 24 1
sceneS Scene_Start_Time Start time of the scene. float 0 1
sceneE Scene_End_Time End time of the scene. float 5 1
timeSys Scene_Time_System Time system used to display times. Name frames 0 or 1 filmcode, frames, seconds, smpte

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.
