Accumulator
Updated: 4 Dec 2023
Accumulate a value based on the input modifiers.
Accumulator
Method #
This node accumulates a value based on the input values, and the specific mode set in the Accumulator Mode attribute. Useful for building counters, or toggle switches.
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.
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.
Value
Base value to modify the output value with.
Accumulator Mode
How the accumulator should accumulate values.
- Value Per Second : the value is added
- Value Delta : The difference between the previous value and the new value is added.
- Value : The whole values is on each frame the node is updated.
- Positive Value Delta : only updates with positive value difference between the current frame and the frame before.
Wrap Mode
How the accumulator wraps when it meets its max value.
- None : the accumulator continues to add values to itself.
- Clamp To Max : The accumulator is clamped, and no longer adds values.
- Wrap : The value wraps back to 0.
Attack
Controls the initial time between the current value to the peak.
Change Threshold
Threshold below which new values will not be added to the accumulator.
Scale
Adjust the scale/range of the modifier.
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.
Max Value
Maximum value the accumulator can reach. Only used with “Clamp To Max” or “Wrap” in the Accumulator node.
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.
