Following up on my previous post, I found a wonderful port of LibNoise for XNA. I've been working with it for about 8 hours straight and I'm tearing my hair out - I just can not get maps to tile, I can't figure out how to do this.

Here's my attempt:

            Perlin perlin = new Perlin(1.2, 1.95, 0.56, 12, 2353, QualityMode.Medium);
        RiggedMultifractal rigged = new RiggedMultifractal();

        Add add = new Add(perlin, rigged);

        // Initialize the noise map
        int mapSize = 64;
        this.m_noiseMap = new Noise2D(mapSize, perlin);
        //this.m_noiseMap.GeneratePlanar(0, 1, -1, 1);

        // Generate the textures

        this.m_noiseMap.GeneratePlanar(-1,1,-1,1);
        this.m_textures[0] = this.m_noiseMap.GetTexture(this.graphics.GraphicsDevice, Gradient.Grayscale);

        this.m_noiseMap.GeneratePlanar(mapSize, mapSize * 2, mapSize, mapSize * 2);
        this.m_textures[1] = this.m_noiseMap.GetTexture(this.graphics.GraphicsDevice, Gradient.Grayscale);

        this.m_noiseMap.GeneratePlanar(-1, 1, -1, 1);
        this.m_textures[2] = this.m_noiseMap.GetTexture(this.graphics.GraphicsDevice, Gradient.Grayscale);

The first and third ones generate fine, they create a perlin noise map - however the middle one, which I wanted to be a continuation of the first (As per my original post), is just a bunch of static.

How exactly do I get this to generate maps that connect to each other, by entering in the mapsize * tile, using the same seed, settings, etc.?
