Overview
The Occlusion distribution samples an ambient occlusion map of the terrain for masking crevices or mountain ridges.
Parameters
- Random Samples
Uses random samples instead of fixed steps. Can improve performance but causes grain on lower values.
- Horizontal Steps
The number of horizontal steps in the occlusion computation.
- Vertical Steps
The number of vertical steps in the occlusion computation.
- Steps
Multiplier for the overall steps.
- Grain
Controls the amount of grain in the final mask.
- Occlusion Range
Allows you to clamp the result of the ao calculation.
- Radius
The sampling radius of the ao algorithm. Smaller values capture smaller scale details, while larger values result in the detection of large scale terrain features.
- Flatten
Improves detection of detail in flat areas.
