shikodesign2000 Posted October 19, 2009 Share Posted October 19, 2009 Hi, I have to make a night render shot for a shopping mall, I face the problem of the high number of vray lights I have to put...... anyhow, the render is very slow at the end cause of these light objects....can anyone tells me a solution for that.. In other words: what the best way to make a good night render scene for a large building without using too much lights?? Link to comment Share on other sites More sharing options...
shikodesign2000 Posted October 19, 2009 Author Share Posted October 19, 2009 i tried to use vray light material, but it didn't give the good effect of the light objects.. Link to comment Share on other sites More sharing options...

LuckyST Posted October 20, 2009 Share Posted October 20, 2009 did you try to limit the lights falloff distance? Link to comment Share on other sites More sharing options...
SandmanNinja Posted October 20, 2009 Share Posted October 20, 2009 I read about someone using a NIGHT HDRI to help with something like this... Link to comment Share on other sites More sharing options...
kippu Posted October 20, 2009 Share Posted October 20, 2009 well you dont have to put individual vray lights for all fixtures that you have ....just put a vray light material in that slot and put some bigger vray lights for the illumination part Link to comment Share on other sites More sharing options...
LuckyST Posted October 20, 2009 Share Posted October 20, 2009 havent tried it, but it might work. instead of using many omnies, try it like this. create one light source (instead of all of the interior lights) turn off the "cast shadows" (that way all of the objects in the scene would be equally illuminated). exclude from illuminating all of the objects in the exterior. (that way only the interior objects would be illuminated by this light source). after that; add a couple of omnies in some of the interiors to make the thing less monotonous. use vray dirt (AO) to simulate the light falloff in the interior. I've used a similar method for lighting up my interiors and results were impressive with impressive render times. Link to comment Share on other sites More sharing options...

Lis Posted October 3, 2011 Share Posted October 3, 2011 Don't use VrayLight. Use Planes with vraylight Material as a light emiters. You can even hide those planes for rendering in Object Properies if you don't want to show emiter object. It's render really fast. Link to comment Share on other sites More sharing options...
