Ambient Occlusion (RTAO)

In: Filters/Effects



Generates an Ambient Occlusion map based on a height map input.

This filter gives more accurate results compared to the HBAO but should not be used in combination with the CPU (SSE) engine due to computation time.

See Ambient Occlusion (HBAO) (Filter Node) for a faster, simpler alternative.



  • Use Physical Size: False/True
    Toggles the Physical size settings on or off.
  • Physical Size: 0.0 - 200.0
    Only visible if Use Physical size is true. Depth and scale of the AO effect is driven through its physical size.
  • Height Scale: 0.0 - 1.0
    Only visible if Use Physical size is false. sets depth and scale of the AO effect.
  • Distribution: Cosine, Uniform
    Sets the distribution method. Affects falloff towards shadowed areas,
  • Maximum Distance: 0.0 - 1.0
    Sets the maximum distance rays can travel to be occluded.
  • Spread Angle: 0.001 - 1.0
    Sets the spreading angle for the rays to be shot at. A value of 1 is a full hemisphere.
