 The **ambient.occlusion** texture property defines the ambient occlusion for a material. In the real world only a fraction of ambient light enters bumps and cravices in objects. This results in such places to be somewhat darker than the rest of the object. In games the low polygon models are flat and such details are only shown using normal mapping. Normal mapping can though not take care of darkening pixels due to ambient occlusion. For this an additional AO map is required storing for each pixel the percentage of ambient lighting potentially hitting this point. The **ambient.occlusion** texture property defines the ambient occlusion for a material.
