Time Stretch
Updated: 1 Sep 2025
Change the time step for child nodes.
Time Stretch
Method #
This node stretches and adjusts the time being passed to all of its children and their respective subtrees that will be used for animation, keyframes and so on. Most commonly used with simulation nodes, such as the Particles or Fields.
Setting this node to “Absolute Time” mode can be a quick way of making a custom curve shape for animating properties based on an incoming value. This can be useful for interactive scenes. Keyframe a property of a child node of the time stretch between 0 and 1 seconds (or any desired range). Then control the time property of the Time Stretch Node to be able to control this custom curve with your input value.
It does not affect visibility as controlled by timeline bars.
Parameters
These properties control the core behaviours of the node.
Parameter Details Time Modification Mode
Change how the time in the child node is affected.
- Speed : The speed that the affected node is played at is modified.
- Absolute Time : Control the absoolute time that the affected node is currently at.
Affects LWS Only
Toggles whether the time stretch only affects Light Wave Scenes.
Time
Change the time that the affected node is currently at, in seconds. Only functions with “absolute time” selected in the time modification mode attribute.
Speed
Change the speed that the affected node is played at. Only functions with “Speed” selected in the time modification mode attribute.
Time Offset
Offset the affected nodes time.
Time Stretch Enabled
Enable or disable the time stretch node.
Previous Time Offset
Deprecated function
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
Inputs
