Trigger keyframed animations on a modifier.
Triggerable Value 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.
Parameter Details Current Value
Shows the current value of the effect. Cannot be directly changed.
Current Play Time
Read-only. The current play time value.
Is Currently Triggered
Read-only. Indicates when the node triggers.
Value
Keyframe this value in the curve editor to design the shape of your trigger envelope.
Scale
Adjust the scale/range of the modifier.
Operation
The 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.
- Replace : Replaces the parameter value.
These properties control the trigger conditions for when the animation should be activated.
Parameter Details Trigger
Triggers the animation set on the Value parameter. When this value is > 0.5, the animation is triggered.
Instant Retrigger
Toggle whether the value can be re-triggered whilst it is still playing.
