  • NOT physically accurate! Only yields good results when used lightly in combination with textures.

  • Huge Z differences cause problem. This can be seen at edges where the mesh meets the sky.

  • Intensity is entirely dependent on the difference in Z value and not the normal rotation of the face.


  • Very generalized setup that works relatively well for all scenes.

  • Several hundreds times faster than ray-traced AO.

  • No other setup required other than the nodes.

  • Independent with camera clip values ·

  • Polygon count independent: can process a scene with 10 million polygon in 1 second.
