FlatbedCarve Node

Carves and blends a flatbed shape along a path into an existing heightmap using a smooth radial falloff. The operator is typically used to create river beds, channels, or flattened corridors that follow a user-defined path.

Inputs

Name	Type	Description
dr	VirtualArray	Optional radial noise map used to perturb the bed shape.
input	VirtualArray	Input heightmap to be modified by the flatbed carving operation.
path	Path	Path defining the centerline along which the flatbed is carved.

Outputs

Name	Type	Description
mask	VirtualArray	Output falloff mask representing the influence region of the flatbed carve.
output	VirtualArray	Resulting heightmap after carving and blending the flatbed along the path.

Parameters

Name	Type	Description
Bed Half-Width	Float	Radius of the flatbed region measured from the path centerline, defining the half-width of the carved bed.
Bed Depth	Float	Vertical depth of the bed carved below the surrounding terrain.
Falloff Width Ratio	Float	Relative width of the smooth transition region outside the bed, expressed as a ratio of the bed half-width.
Outer Linear Slope	Float	Linear slope applied beyond the falloff region to smoothly reconnect the bed to the surrounding terrain.
Preserve Bed Shape	Bool	Preserves the original bed profile when radial noise is applied, preventing distortion of the flatbed shape.
Profile Type	Enumeration	Radial profile function used to define the cross-sectional shape of the bed (e.g. smoothstep, linear).
Profile Sharpness	Float	Shape parameter controlling the curvature or sharpness of the selected radial profile.
Bed Base Height	Float	Minimum height value assigned to the bed bottom, defining the base elevation of the carved region.
