Ambient Occlusion
Ambient Occlusion
Use Ambient Occlusion to estimate contact shadowing from height-like inputs. It adds depth cues that improve readability in previews and material maps.
Availability
This node is available in the free feature set.
Common uses
- Use analysis outputs as masks or support maps in blend chains.
- Pair with levels or threshold nodes to isolate useful map ranges.
Input ports
-
input -
Usually expects a structured grayscale or height-like input.
Output ports
-
out -
Outputs one or more analysis maps depending on node type.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Radius | float | 10 | 1 to 50 |
| Strength | float | 1 | 0 to 10 |
| Bias | float | 0.1 | 0 to 1 |
| Samples | int | 16 | 4 to 128 |
| Noise | float | 1 | 0 to 1 |
Behavior
- These nodes compute derived data from shape and height information.
- Outputs are often best consumed by downstream utility and mixing nodes.
Common mistakes
- Analysis nodes can be sensitive to noisy or low-contrast inputs.
- Map interpretation changes with downstream color-space assumptions.
