Sketchrender Posted December 18, 2013 Share Posted December 18, 2013 Hi Interior of an Auditorium. Image attached, I can't get the lighting sharp enough to get rid of the artefacts. I am sure it is subdivisions issue. I am using Vray light material, I had tried Vray light also, but to the same end. Any help would be grateful. Thank you.

Ismael Posted December 18, 2013 Share Posted December 18, 2013 Do you have V-Ray 2.something? Maybe try the Retrace threshold parameter. http://help.chaosgroup.com/vray/help/200R1/examples_lightcache.htm Link to comment Share on other sites More sharing options...
Francisco Penaloza Posted December 18, 2013 Share Posted December 18, 2013 I am not sure what I am looking at, what it the light? the one on the ceiling or the one on the wall? did you check your normal or double geometry? are you using dirt map in any close surface?
