The Remap Amplitude component changes the shape of the Source curve by modifying its amplitude based on the shape of the Remap curve. This is a curve component, it can be located in the Curve Ops category on the Components Bar. Technically, the output value of the resulting curve at each point is obtained by evaluating the Remap function with the Source function as an argument: Y = Remap(Source(X)). See a visual explanation below:
Source: Curve Input, Required
Provides the source curve to be remapped. This is a required input – to make the Remap Amplitude component work, this input must be connected.
Remap: Curve Input, Required
Provides the remap curve, based on which the component will change the shape of the Source curve. For predictable results, you can experiment with curves that start at 0%, end at 100%, for example Linear, Gain, Bias, Gamma, and Stairs, or any curve produced by a Fade component with Fade From set to 0% and Fade To set to 100%. This is a required input – to make the Remap Amplitude component work, this input must be connected.
