manta Posted April 21, 2008 Share Posted April 21, 2008 do you really need the lights on with the blaring sunlight ? try turning them all off to see if that is in fact the cause of the long render times...if it is, there may be a work around... and be sure your glass material has "affect shadows" checked, so that the sunlight will go through it...

blade911 Posted April 21, 2008 Author Share Posted April 21, 2008 thanks for ritin in man those shops turn out real dark without the lights and if i increase the exposure the sunlight burns out. n i figured the lights are turned on in the shops after visitng a mall with a large skylight n so on. n yeah the affect shadows is on. oh n im supposed to fill the whole place with foliage. neone got ne ideas as to how to go abt it? i have some evermotion plants but they make my machine go crazy. even when theyr proxies.. need some pointers guys.. thanks Link to comment Share on other sites More sharing options...
manta Posted April 21, 2008 Share Posted April 21, 2008 so are you saying that the lights are the source of the long render times ? what do you mean when you say that vray proxies make your machine go crazy ? Link to comment Share on other sites More sharing options...
kippu Posted April 21, 2008 Share Posted April 21, 2008 alrite try this ...remove the glass on top from GI calculations .. use the lights in the offices just as if they are on and instead use bigger vray lights which covers the whole room and make that store with irrmap ...and see how these affect your rendertime Link to comment Share on other sites More sharing options...
blade911 Posted April 21, 2008 Author Share Posted April 21, 2008 @manta machine goin crazy meant it takes so long to calculate irr and render . not sure if its the lights, ive worked on scene with more lights n didnt face ne trouble. i really suspect its all the glass in there. is there ne way to counter that? @maria doin tat to the skylight doesn make ne difference. there is also tat stone map tat u see which has a bump on it as well as the floor texture which has reflection properties as well. how do u suggest adding lots of foliage in there as well?

manta Posted April 22, 2008 Share Posted April 22, 2008 Start eliminating possibilities then you'll be left with only one possibility, that's called deductive reasoning...guessing isn't going to get you anywhere... Link to comment Share on other sites More sharing options...
RobNJ73 Posted April 23, 2008 Share Posted April 23, 2008 Just a passing thought, but you could keep those lights in the shops off and just balance the resulting darkness with some adjustments to your color mapping. Link to comment Share on other sites More sharing options...
blade911 Posted April 24, 2008 Author Share Posted April 24, 2008 thanks guys. yeah turnin the lights off seem to be helping. i really need help with the foliage. wats the best way to show large amts of plants n thins? Link to comment Share on other sites More sharing options...
jreben Posted April 28, 2008 Share Posted April 28, 2008 Might also exclude glass objects from casting shadows. Use 3d plants if possible and if there are more than a few use vray proxies. Link to comment Share on other sites More sharing options...
Claudio Branch Posted April 28, 2008 Share Posted April 28, 2008 i really need help with the foliage. wats the best way to show large amts of plants n thins? Onyx trees as proxies and/or Forest Pro... Link to comment Share on other sites More sharing options...
Claudio Branch Posted April 29, 2008 Share Posted April 29, 2008 ...the stone texture on the ground needs to be mapped better. I agree. The stone surface shown in the forground is an ideal candidate for V-Ray displacement. The camera is so close that you really should consider using it.

blade911 Posted May 6, 2008 Author Share Posted May 6, 2008 I agree. The stone surface shown in the forground is an ideal candidate for V-Ray displacement. The camera is so close that you really should consider using it. oh yeah very much know abt vray displacement. i didnt turn it on cus tat was makin the render times even crazier. anyway i solved the issue by jus creating light objects n applyin vray light mats to them instead of using vray lights. turned down the time a lotl. thanks for all the tips guys cheers Link to comment Share on other sites More sharing options...
