ivan Posted February 26, 2009 Share Posted February 26, 2009 there used to be the choice of "closest surfce" shadow pic generation. Is this no longer possible? Quote Link to comment Share on other sites More sharing options...
eetu Posted February 26, 2009 Share Posted February 26, 2009 Maybe unticking the "Transparent Shadows" checkbox in shadow parameters? Shadows will be computed using a depth map. When transparent shadows are turned on, deep shadow maps will be used. Otherwise, simple z-depth shadow maps will be used. eetu. Quote Link to comment Share on other sites More sharing options...
ivan Posted February 26, 2009 Author Share Posted February 26, 2009 nope- that isn't closest surface. It's not possible. I found a workaround.

Jason Posted February 26, 2009 Share Posted February 26, 2009 nope- that isn't closest surface. It's not possible. I found a workaround. Sure, its "closest", "minmax min" sample- and pixel-filters, no? Quote Link to comment Share on other sites More sharing options...
eetu Posted March 3, 2009 Share Posted March 3, 2009 nope- that isn't closest surface. Out of curiosity, what are mantra depth maps then if not closest surface? Some sort of "midpoint between first 2 hits" or something? Or did you just mean the filtering on the edges? What was the workaround? eetu. feeling inquisitive.

It can choose to take the nearest sample, the farthest or the midpoint of the N samples. If the samples are 1x1 (default for a light), then there's no semantic difference between the sampling modes. The setting is perhaps more important on deep shadow maps where it affects how the DSM pixels get compressed. Quote Link to comment Share on other sites More sharing options...
