Occlusion

Overview

The Occlusion distribution samples an ambient occlusion map of the terrain for masking crevices or mountain ridges.

Parameters

Properties	Description
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.
