    • · Use filter for soft shadows
    • · Use disk-based dmap by changing to Overwrite existing dmap(s) . Use fcheck to view it (renderdata/depth). Need to hit Z-buffer button in fcheck to see depth information.
    • · Add frame ext – use for animated lights and/or objects
    • · change to reuse depth maps after you are happy with the placement of lights and objects
    • · fake transparent dmaps with lighter shadows
