Bent Normal

In: Filters/Normal Map

Intermediate

Description

Generates a Bent Normal Map based on a height map input. A Bent Normal map is a special version of Normal and Ambient Occlusion (RTAO), generating a normalmap with embedded Ambient occlusion. This can be used in realtime engines to have Ambient Occlusion baked into the normalmap.

This node should not be used in combination with the CPU (SSE) engine due to computation time.

Parameters

  • Use Physical Size: False/True
    Toggle to use Physical size settings to determine intensities.
  • Physical Size: 0.0 - 200.0
    Only available if Use Physical Size is True. set to determine intensities.
  • Height Scale: 0.0 - 1.0
    Multiplier to interpret Height map input by.
  • 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.
