nowikovs12 Posted May 5, 2010 Share Posted May 5, 2010 Hi there I am having problems with my rendered pictures, they come out very grainy,.. I have increased for the mr sky portals the "shadow samples to 64" but that doesn't make any difference, I think it has to do with the material? I am using art & design, polished concrete, but in the render you can see,.. that the grains are not only on the floor,.... I 'm using, mental ray, daylight system, mr sky portals, environment map - mr physical sky - mr photographic exposure control, indoor daylight, render settings, final gather on, multiplier 1.0, fg point dencity - 1.0, reys per fig - 200, interpolate over num. fg points - 50, difuse bounces - 0. global ilumination off. any ideas? thanks Quote Link to comment Share on other sites More sharing options...
Cad64 Posted May 5, 2010 Share Posted May 5, 2010 What is your render output size? What is your sampling quality set to? Minimum and Maximum? What Filter type are you using? Quote Link to comment Share on other sites More sharing options...
nowikovs12 Posted May 5, 2010 Author Share Posted May 5, 2010 Hi cad64 Output size is - 280x200 ,.... these settings are new to me: minimum is 1/4 maximum is 4 (this setting is to reduce jagged edges right?) the filter type is box? ,.... width and height set to 1.0 Quote Link to comment Share on other sites More sharing options...
Cad64 Posted May 5, 2010 Share Posted May 5, 2010 Ok, those settings are no good if you want a quality render. The first thing you need to do is decide what size your output needs to be. 8-1/2x11"? 11"x17"? Bigger? Use the print size assistant in the "Rendering" menu. It will allow you to pick your output paper size and resolution, (I generally use 150 DPI). Once you pick your settings, click the "Render Setup" button. Set Minimum Samples to 4 and Maximum to 16 Set Filter type to Mitchell But be aware that by using the settings above, your render time will increase substantially.
