This is Unity 5.0.0f4, OSX 10.9.5

No matter what I input to PerlinNoise, the result is always exactly 0.4652731.

Debug.Log (Mathf.PerlinNoise(0f, 0f));
Debug.Log (Mathf.PerlinNoise(1337f, 42f));
Debug.Log (Mathf.PerlinNoise(100f, 3.1415f));

(output)
0.4652731
0.4652731
0.4652731

My understanding is that Perlin noise always has the same value at integer coordinates. Try values that aren’t on an integer boundary.

Here’s a discussion in the forums: http://forum.unity3d.com/threads/perlinnoise-not-working.318773/

Try:

Debug.Log (Mathf.PerlinNoise(0f, 0f));
Debug.Log (Mathf.PerlinNoise(0.1f, 0.1f));
Debug.Log (Mathf.PerlinNoise(0.5f, 0.5f));

The example at:

basically uses the x and y arguments in the range 0…1.
