Generates a texture following the pattern defined by the Noise Type.
- Noise Type: The pattern to generate. See Noise Types
- Min Max Height: The minimum and maximum value of height that the pattern will take. It is recommended to consider the units to be the same as your scene. Ex: A maximum of 2 should represent a maximum height of 2 meters.
- Tile Size: The size of a pattern. A big size will spread out the features of the noise making them less recognizable but a smoother terrain, while a small size will create more prominent features.
Scale of 40
Scale of 100
Scale of 300
- Octaves: Represent how many frequencies are going to be used for the generation of noise. More octaves means more low-level detail but slightly more expensive. It is recommended to keep the value of octaves between 1 and 10.
1 Octave
2 Octaves
8 Octaves
- Rotation: A rotation matrix that gets applied to the noise.
- Lacunarity: Enabled if there is more than 1 octave. Defines how each frequency is scaled for the subsequent passes. Normally the value should stay around 2 to 10.
2 Octaves, 2 Lcaunarity
2 Octaves, 8 Lacunarity
- Persistence: Enabled if there is more than 1 octave. Defines how much is the amplitude reduced between octaves.
2 Octaves, 2 Lacunarity, 0 Persistance
2 Octaves, 2 Lacunarity, 1 Persistance
- Ridge Mode: Folds the noise values through the middle to create a ridge like effect.

Feature Extraction
Notes
We start by creating the terrain using a simple Perlin Noise with a few octaves.
Next, we connect it to the Height Output to ensure the data will be used, and then extract features using the Get Slope and Get Cavity nodes. We use the data generated by these nodes to select specific regions—such as areas with high slope or regions where the terrain is relatively flat—and paint them using the Color Output.
Finally, using the Fold node, we transform the flat region mask into a selection of all concave and convex areas.

Crop Pattern
Notes
We’ll start by creating a Voronoi Noise node and setting the Noise Type to Voronoi Index. This gives us flat regions with a single value across each region, which we can isolate using a Select Mask.
This mask defines the area where the pattern should appear. To smooth the boundary, we first blur the Voronoi noise with the Blur node, then reselect our region. Finally, we use Apply Mask to ensure that no values appear outside the selected area.
With our masked zone in place, we can use a Function node to generate the desired pattern and combine it with the Apply Mask node.
To break up uniformity, we then apply some warping to the entire pattern using the Warp node.

Desert Pyramids
Recipe
Notes
To place different pyramid-like structures, we start by creating a grid of points and randomly positioning them. We use the Jitter Points Node to randomize their position, rotation, and scale.
At each of these points, we create a pyramid using the Shape Node and spawn it with the Points To Height Node. By ticking the required boxes, we ensure that the sampled shape follows the points data correctly.
Next, we apply some stepping to the pyramids to add texture, making them look more like layered cubes.
We then combine the pyramids with basic noise to give them a less uniform look, as though there’s sand on top of each layer.
Finally, we blend these pyramids with some Simplex Noise to achieve the final terrain.
