Normal Cavity


  • Where to find it:


    • Add Adjustment Layer / Extension Pack / Normal Map /


    • NodeGraph / Right Mouse Click / Nodes / Filter / Extension Pack / Normal Map /





Normal Cavity will create a pseudo cavity map based on your normal map.

The Nodes options behaves very similar to a Levels Adjustment after a channel specific weight.

16bit Normal Maps will give better results than 8bit.





Behaviour


  • Red Channel hSv (saturation) will result in values being subtracted from the final result. 
  • Red Channel hsV (Value) is ignored
  • Red Channel Midpoint is 0.5


  • Green Channel hsV (value) will result in value being added to the final result. 
  • Green Channel hSv (saturation) is ignored
  • Green channels Midpoint is 0.8


  • Blue Channel hSv (saturation) will result in values being subtracted from the final result. 
  • Blue Channel hsV (Value) is ignored
  • Blue Channel Midpoint is 0.5


  • wh / md / blk options are a regular level on the final contribution
