Step

The Posteriser. Creates hard transitions by comparing an input map to a threshold. Unlike the Threshold node, the Step node outputs a Float (0.0 or 1.0) rather than a Bool Mask.

Ports

Port	Type	Direction	Description
Input	Float	Input	The source float map.
Output	Float	Output	Either 0.0 or 1.0.

Logic

The Step node returns 1.0 for any cell where the input is greater than or equal to the threshold, and 0.0 otherwise.

Formula: (Input >= Threshold) ? 1.0 : 0.0

Parameters

• Threshold: The cutoff value for the step transition.

Potential Use Cases

• Hard Edges: Convert a smooth gradient into a sharp "cliff" edge for terrain.
• Mask Preparation: Generate a float-based mask for use in Layer Blend nodes where a boolean mask cannot be connected directly.
