This ensures that the light cache is consistent across computers with a different number of CPUs. Each pass is rendered in a separate thread independently of the other passes. Number of Passes – The light cache is computed in several passes, which are then combined into the final light cache.The actual number of paths is the squared value of the subdivs (the default 1000 subdivs mean that 1 000 000 paths will be traced from the camera. Subdivs – Determines how many paths are traced from the camera.Each of the bounces in the path stores the illumination from the rest of the path into a 3d structure. Light Cache – The light map is built by tracing many eye paths from the camera.

For the “Light Cache” set the “Subdivs” to 1500, and for “No of Passes” set the value to 8.
