Height Blend

Utilities

Blends two height maps and outputs the height and foreground coverage mask.

Select a node to adjust its parameters. Double-click a node to inspect.

Inputs

  • foreground : Foreground height map. Uses the red channel as height.
  • background : Background height map. Balanced Height can lower its range as Height Offset rises above 0.5.
  • opacity_map (optional) : Optional mask applied to the height ranges before comparison. Black sets Top Height to zero and restores the original bottom range; white applies the full remapping.

Parameters

ParameterTypeDefaultRangeDescription
height_offset
Height Offset
float0.50 to 1Remaps the height ranges. 0.5 leaves both ranges unchanged; lower values compress Top Height, while higher values favor it according to Mode.
contrast
Contrast
float0.90 to 1Sharpens the linear height mask. Top gets full coverage wherever it is at least as high as Bottom; lower Top heights fade across a difference of 1 minus Contrast.
mode
Mode
enumbalancedHow Height Offset remaps the two height ranges.
  • balanced : Below offset 0.5, compress the top range toward zero. Above 0.5, compress the bottom range toward zero.
  • bottom_priority : Keep the bottom range unchanged. Above offset 0.5, raise the minimum top height toward one.
opacity
Opacity
float10 to 1Multiplies the output height mask. 0 returns the remapped bottom height and a black mask.

Outputs

  • height (default format: r32float)
  • mask (default format: r32float)
