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.

For an alternative, more advanced but slower version of AO, see Ambient Occlusion (RTAO)

Parameters

• Use World Units: False/TrueToggles use of world or sceen-space units. Enables extra parameters that allow for more precise control.
• Height Depth: 0.0 - 1.0Only used when World Units is set to False. Controls global scaling.
• Surface Size: 0.0 - 1000.0Only used when World Units is set to True. Controls global scaling.
• Height Scale (cm): 0.0 - 1000.0Only used when World Units is set to True. Controls global scaling.
• Radius: 0.0 - 1.0Controls the spread of the AO.
• Quality: 4 samples, 8 samples, 16 samples
  Sets Quality level by determining amount of samples used for calculation.
• GPU Optimization: False/TrueEnables internal GPU optimisation, speeds up processing.
