Height Blend
Height Blend
Use Height Blend to mix materials based on relative height influence instead of simple opacity. It preserves relief hierarchy in layered surface workflows.
Availability
This node requires Pro.
Common uses
- Normalize inputs before mixing for predictable blends.
- Use masks and height maps to control which regions dominate.
Input ports
-
heightTop -
heightBottom -
mask -
Expects two or more input branches depending on node type.
Output ports
-
height -
mask -
Outputs the mixed result and optional helper maps for some nodes.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Height Offset | float | 0.5 | 0 to 1 |
| Contrast | float | 0.5 | 0 to 1 |
| Mode | enum | balanced | balanced, bottomPriority |
| Opacity | float | 1 | 0 to 1 |
Behavior
- Mixing nodes merge, select, or route among multiple incoming signals.
- Blend behavior depends on selected mode and input value ranges.
Common mistakes
- Input range mismatches can make blend results look clipped or washed out.
- Switch-based nodes can hide inactive branches during debugging.
