Click to fill in the Min and Max parameters with the current minimum and maximum values in the input layer.

The lowest value in the input to map from.

The highest value in the input to map from.

Enables the evolution of 'temperature' depending on the elevation.

The rate of temperature decrease with height. Measured in °C/km. If the value is positive, temperature decreases as height increases. If the value is negative, temperature increases as height increases.

Enables the blurring of temperature between different regions.

Higher values will result in a smoother gradient, but will take longer to calculate.

Remove 'precipitation' in areas based on the terrain convexity. By default, more convex areas are assumed to have higher wind exposure, giving rise to increased evaporation and drier terrain.

Modify this ramp to use a custom remapping.

Control Remove by Convexity removal amount by height. By default, this removes 'precipitation' from the convex high mountain peaks without removing 'precipitation' from the low flat plains. The mask by height is multiplied by the mask by convexity.

Modify this ramp to use a custom remapping.

Remove 'precipitation' based on the “horizontal” direction the terrain surface faces at a given point.

Start direction vector of Rain Shadow. This could be a vector derived from the location of the ocean that is causing the rain shadow.

Offset rotation of Rain XZ Direction.

Amount of falloff allowed around the rain shadow.

Modify this ramp to use a custom remapping of Falloff Angle.

Remove 'soil' based on the slope of the terrain.

Add areas with a slope greater than or equal to this value to the mask. If the Removal Amount over Slope Angle ramp is set to default, any slope less than this value will have a soil value of 1.

Add areas with a slope less than or equal to this value to the mask. If the Removal Amount over Slope Angle ramp is set to default, any slope greater than this value will have a soil value of 0.

Controls the value of the mask over the range from the Min Slope Angle to the Max Slope Angle. This lets you control the feathering of the mask.

Remove 'soil' based on the height level of the terrain. By default, when this is enabled, this will prevent plants from spawning at extremely high elevations, regardless of the slope. When both Remove by Height and Remove by Slope are enabled the masks are multiplied. The inverse of this product is the 'cliff' layer.

Controls the value of the mask over the range from the minimum height level to the maximum height level of the heightfield.

Remove 'soil' based on a noise.

The base or minimum value of the soil mask.

Reverse the noise mask values.

#intensity The intensity of the noise. Lower values fade the noise away.

Scales the intensity of the noise mask.

Scales the noise pattern outward across the grid.

The type of noise to generate, Different algorithms generate patterns with different characteristics.

Whether to do multiple iterations of smaller noise on top of bigger noise.

None:

Does not add any additional noise on top of the basic noise.

Standard:

Adds pseudo-random noise on top of the basic output.

Terrain:

Adds noise like “standard” but dampens the noise in the valleys, which generates more realistic-looking terrain.

Hybrid Terrain:

Like terrain, but with more sharpness in the valleys.

Limits the fractal noise to a certain number of iterations.

The frequency increment between iterations of fractal noise is added to the basic output. Note you can use negative values.

Fractal roughness. The roughness parameter determines the coarseness of the noise.

Use custom mask from the first input for soil.

The name of the custom mask from the first input to use. Ensure that the mask is mapped with values from 0 to 1.

How to composite the mask with the Soil Noise mask. If Remove by Noise is disabled, this value is disabled.

The amount to blend the custom mask with the soil mask, when Combine with Noise is “blend”. A value of 0 uses the soil mask, a value of 1 uses the custom mask, a value of 0.5 blends equally between the two masks. Visualize this change by setting Display to “Soil” and “Use Real-World Range”.
