Overview
The noise filters allow you to add procedural noise effects to your terrain. For a full overview of all the noise types take a look at this article. This article roughly documents the following filters:
- Billow Noise
- Gabor Noise
- Perlin Noise
- Phasor Noise
- Ridged Noise
- Simplex Noise
- Value Noise
- Voronoi Noise
- Wave Noise
- White Noise
Parameters
All of these parameters are explained in further detail in the main noise article.
- Placement
Allows you to specify the location and rotation of the noise.
- Noise
Parameters specific to the type of noise.
- Noise - Operation
Offers the typical blending operations like multiply, overwrite, add or subtract but also more advanced functionality like distortion.
- Fractal
Offers a fbm and ridged combination methods for the noise.
- Domain Warping
Allows you to add additional distortion to the noise.
