Using a fill layer, you can now generate a simplex gradient noise texture. This noise can be looped seamlessly, distorted in two dimensions, and given a string of text to use as an optional custom seed value. This new generator plugin makes use of a C port of Kurt Spencer's permissive, open source, and patent-free OpenSimplex noise implementation. If no custom seed string is given, a seed number will be chosen randomly. In order to achieve seamless looping without distortion we generate noise in 4-dimensions, and sample each pixel from a toroidal (doughnut-shaped) pattern. In order to keep the look of the noise consistent between looping and non-looping modes, both are sampled from 4-dimensions. - Eoin and Emmet O'Neill.
