Ambient Occlusion (HBAO) (Filter Node)


Ambient Occlusion (HBAO)

In: Filters/Effects

Intermediate

Description

Takes a Heightmap as input and generates an Ambient Occlusion map from that. It uses Horizon-Based Ambient Occlusion, an algorithm originally intended for screen-space realtime AO-generation. Very useful for creating procedural AO maps from procedural Heightmaps.

Parameters

  • Use World UnitsFalse/True
    Toggles use of world or sceen-space units. Enables extra parameters that allow for more precise control.
  • Height Depth0.0 - 1.0
    Only used when World Units is set to False. Controls global scaling.
  • Surface Size0.0 - 1000.0
    Only used when World Units is set to True. Controls global scaling.
  • Height Scale (cm)0.0 - 1000.0
    Only used when World Units is set to True. Controls global scaling.
  • Radius0.0 - 1.0
    Controls the spread of the AO.
  • Quality4 samples, 8 samples, 16 samples
    Sets Quality level by determining amount of samples used for calculation.
  • GPU OptimizationFalse/True
    Enables internal GPU optimisation, speeds up processing.
