Filter that produces 3D Simplex Noise
the value to add to the resulting noise
decay is the amount by which gain is modulated per octave, default is Vector4(0.5, 0.5, 0.5, 0.5)
gain is the base intensity per channel, default is Vector2(1.0, 1.0, 1.0, 1.0)
lacunarity is the amount by which scale is modulated per octave, default is Vector3(2.0, 2.0, 2.0)
the number of octaves of noise to generate, default is 4
should the output colors be multiplied by the alpha channel, default is true
base noise scale, default is Vector3(1.0, 1.0, 1.0)
