After creating the scene, go to in render setup,change the render engine from scanline to mental ray. Now take a material  and apply mentalray map - Ambient/Reflective Occlusion in the diffuse of that material . Then apply on your scene and take the render. Now we got the basic occlusion . Now we can work on the various parameters like max distance and Spread. For the quality enhancement we have to increase the sample value, but remember more sample value means more render time.
