Occlusion

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.
