SimplexNoise Plugin v5.1+

 SimplexNoise Plugin v5.1+ is a clean, fast, modern, and free Perlin Simplex noise function designed for Unreal Engine. It supports 1D, 2D, 3D, and 4D noise generation. The plugin includes scaled and in-range versions of the noise functions, with output values ranging from 0 to 1, 0 to a user-defined scale factor, and between a specified minRange and maxRange respectively. All public functions are BlueprintCallable, enabling seamless integration into any Blueprint. The noise functions accept parameters such as lacunarity, persistence, octaves, and inFactor (which controls frequency, recommended values between 0.1 and 0.00001) to fine-tune the noise pattern. The available functions include GetSimpleNoise1D_EX, GetSimpleNoise2D_EX, GetSimpleNoise3D_EX, and GetSimpleNoise4D_EX, each with optional parameters for frequency, octaves, and output range.
