tfNoise generates a height field based on fractal noise functions, to get realistic-looking results.

The Turbulence setting, in Noise Type is driving the terrain on the right, with the 2D height map on the left illustrating.

Properties tab

In the Properties tab are all of the aspects which create the noise.

Mode

Set as Maxon, by default, this will give you access to the standard Noise Type options and settings.

Changing the Mode to Advanced will offer you some very interesting options.

For some Noise Types in the Advanced Mode, there will be additional parameters available, explained below.

Noise Type

With the Mode set as Maxon, Turbulence is the default setting, but there are many of the other standard noise types available (only the ones which are suitable for terrain generation).

Image to show the fourteen Noise Type settings available, with the Mode set to Maxon.

Changing the Mode setting to Advanced will reveal further interesting, alternative noise types: Value, Perlin, Simplex, Cubic, Gabor, Cellular, Prairie (Macro) and Mixed (Macro).
