Triggerable Value Modifier

Triggerable Value Modifier

Updated: 21 Aug 2025

Trigger keyframed animations on a modifier.

Method #

This node is used for triggerable animations on a specific value. Keyframes on the value property will only be played back until the trigger values condition has been met, where the value then plays back at a normal rate and holds its final value until the trigger is re-activated.

The output is a numeric value that can be further processed with other modifiers, or directly connected to a parameter in another node, using the operation method selected.

To use this node, keyframe the value property so that it has a curve you want to be played when the trigger condition is reached.

Then tune your trigger condition so that it is triggered based on your incoming threshold value.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
Current ValueShows the current value of the effect. Cannot be directly changed.
Current Play TimeRead-only. The current play time value.

OperationThe operation to be performed on the targeted parameter.
  • Add : Adds to the parameter value.
  • Subtract : Subtracts from the parameter value.
  • Multiply : Multiplies the parameter value.
