UnitySimplexNoise

a compact and functional system for generating complex simplex noise layers for procedural generation

the simplest implementation with in-editor control

            // with the noiseLayer properties passed to the function.

            // of generators across a bunch of different classes
            var noiseValue = Noise.GenerateValue(noiseLayer, vector3);
