Envelope Modifier

Envelope Modifier

Generates a numeric value or alters a numeric value from another Modifier.

Method #

This node generates a simple numeric value, or modifies an input value from another Modifier. You can use it to Add, Subtract, Multiply or Replace values.

The output of the node is a numeric value that can be further processed with other modifiers, or directly connected to an attribute in another node.


These properties control the core behaviours of the node.

Current ValueShows the current value of the effect. Cannot be directly changed.
ValueBase value to modify the output value with.
ScaleAdjust the scale/range of the modifier.
ThresholdChanges the threshold for what counts toward the modifier.
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.
  • Replace : Replaces the parameter value.
Incoming OperationWhat operation is done to the incoming value.
  • None : The incoming value is only manipulated by the Scale.
  • Invert : Subtract the current value from 1.
  • Above Threshold : Above Threshold value is 1.0 multiplied by the Scale, else 0.0.
  • Below Threshold : Above Threshold value is 1.0 multiplied by the Scale, else 0.0.
  • Absolute : Treats all values as positive, ignoring the sign.
  • Module (with Threshold) : Uses the remainder value after it is divided by the threshold value.
  • Positive Modulo (with Threshold) : Divides the value to find the remainder using the threshold, and ignores the sign.
