+====== Ambient Occlusion Maps ======
+The Ambient Occlusion maps within Knald are generated on the fly from the Normal & Height Maps provided by [[the_integrator_knald_1.1|The Integrator.]] They are adjustable in real time and produce extremely high quality and clean results that rival baked AO at 600+ rays.
+You can also generate Ambient Occlusion from high to low polygonal meshes via [[the_baker_knald_1.1|The Baker]].

+**AO Scale:** The strength of the image based AO, irrespective of the Global Intensity slider.
+**Activate** This check box is a toggle to enable and disable Low Poly Ambient Occlusion via an imported mesh.
+**Opacity:** The level of opacity used when mixing the Low Poly Ambient Occlusion with the image based Ambient Occlusion.
+**Rays:** This slider is used to determine the number of samples in a discrete evaluation of the integral across the half sphere for diffuse outgoing radiance with a constant radiance field with a minimum of 256 and maximum of 8192 rays being available.
+  * A higher number or rays will increase the quality of the Mesh Ambient Occlusion at the cost of speed.
+  * We do not recommend going below a value of 512 rays as this can cause banding to appear in the map.
+  * A value of 1024-2048 or above should be perfect for production.
+**Bias:** A bias value based upon mesh density. A value of 10 should be good in most situations.

+**Ignore Backface Hits** Checking this option ignores backface ray hits, which is useful in instances where you are using floating geometry on the High Poly mesh.
