Noise Remap
3 different noise types and exemplary remapping curves, on the right multiplied by a spherical field (Plain effector for a Matrix object). The area marked by dashes is scaled by Scale and shifted by Offset.
This layer redistributes the child field values. This means, for example, that the value range of a spherical field, which runs linearly from 0 to 1 according to the default settings, is transformed by a noise curve. Imagine the noise values as a curve (as shown in yellow above).
