	// Trace code for UE4. Make sure you set a custom Object Channel (not Trace Channel) in the project settings under Engine - Collision.
	// Reboot UE4 to take effect if necessary.
	// Create a custom collision preset with Object Type set to your new channel.
	// In your code, the channel is referenced as ECC_GameTraceChannel[0-18]. Make #define to alias it.
	// Check Config/DefaultEngine.ini. Comparing different values and tests helped me a lot.

Created September 8, 2017 12:18 — forked from Flafla2/Perlin_Tiled.cs

A slightly modified implementation of Ken Perlin's improved noise that allows for tiling the noise arbitrarily.

	public class Perlin {

	public int repeat;

	public Perlin(int repeat = -1) {
	this.repeat = repeat;
	}

	public double OctavePerlin(double x, double y, double z, int octaves, double persistence) {
	double total = 0;
