Here it is: routine for realtime changes of RidgeNoise parameters. Though, still no luck with terrain tweaking: i would like to have plain territory with sevaral mountains. If anybody has settings for it - you’re wellcome to share. I guess, i should scale its ox-oy axis’s
Now i got something like this:
using UnityEngine;
using CoherentNoise;
using CoherentNoise.Generation;
using CoherentNoise.Generation.Displacement;
using CoherentNoise.Generation.Fractal;
using CoherentNoise.Generation.Modification;
using CoherentNoise.Generation.Patterns;
using CoherentNoise.Texturing;

float _lac = 1.2f;
float _oct = 4;
float _exp = 1;
float _off = 1;
float _gain = 2;
float _mul = 0.6f;
// Use this for initialization
private void Awake()
{
Debug.Log("Starting particles");
points = new ParticleSystem.Particle[64*64];
Rebuild();
}
private void Rebuild()
{
var desert = //new Gain(
// new ValueNoise2D(23456) * 0.6f, 0.1f);
new RidgeNoise(23478568)
{
Frequency = _freq, // 1
Lacunarity = _lac, // 2.17
OctaveCount = (int)_oct, // 4
Exponent = _exp, // 1
Offset = _off, // 1
Gain = _gain // 2
} * _mul ; //, 0.3f);
var terrainGenerator = desert.ScaleShift(0.5f, 0.5f);
count = 0;
for (int x = -31; x < 32; x++)
{
for (int y = -31; y < 32; y++)
{
int z = 0;
float groundHeight = terrainGenerator.GetValue(x, y, 0);
points[count].position = new Vector3(x, groundHeight, y);
points[count].color = new Color(0f, 0f, 0f);
points[count].size = 1f;
count++;
}
}
}
