Stan Zaslavsky Posted May 7, 2009 Share Posted May 7, 2009 Hi guys, here is a job i'm working on atm. i'm trying to light up the interior so it gets that nice look inside. For some reason when i put in lights - they don't light up quite as much. i've got sky portals in front of windows with the flux light pointing inside. any tips?

maciejwypych Posted May 7, 2009 Share Posted May 7, 2009 1.Your glass is quite reflective so it will be difficult to see what's inside. (go and take a photo of a house next door and compare the glazing with yours) 2. You can cheat a little by adding a light inside the house with non realistic illuminance levels 3. Turn on GI if you didn't already it will help to make the light distribution inside the house more realistic. Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted May 7, 2009 Author Share Posted May 7, 2009 thats brilliant - i didn't think of nu3 - in exteriors i've only used fg w/out gi. thanks so much for the tips maciej Link to comment Share on other sites More sharing options...
WAcky Posted May 7, 2009 Share Posted May 7, 2009 You might want to look up light portals as well. They're used to "push" lighting in a direction (so line one up with window sets) and im almost 100% sure mental ray has this function... Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted May 7, 2009 Author Share Posted May 7, 2009 hey james thanks for that - i am using light portals (in mr they're called sky portals) maciej was absolutely right - my glass was too reflective and wasn't letting light in - i've modified this now and should have an updated image with some interior showing through up soon cheers Link to comment Share on other sites More sharing options...
Horhe Posted May 7, 2009 Share Posted May 7, 2009 Well seems youve sorted out how to lit up the interior, but the vegetation is too saturated and overexposed, turn it down a knotch or two. Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted May 7, 2009 Author Share Posted May 7, 2009 hi jakub thanks for the comments - this is where i'm at currently the vegetation is a bit unnaturally green ... i wonder whether thats in my material settings rather than exposure of the image?

You can turn down the diffuse property on those green guys in front. Link to comment Share on other sites More sharing options...
cjjat puresilica Posted May 7, 2009 Share Posted May 7, 2009 I have found that I have to incease the interior light levels quite significantly i.e by 100's if not 1,000's to get the interior lights to show up. Link to comment Share on other sites More sharing options...
Horhe Posted May 7, 2009 Share Posted May 7, 2009 (edited) hi jakub thanks for the comments - this is where i'm at currently the vegetation is a bit unnaturally green ... i wonder whether thats in my material settings rather than exposure of the image? Yes I meant tuning down the diffuse value (like Robert said). Either change the output value if a bitmap is mapped onto the leaves, or just turn down the brightness of the leaves colour.

WAcky Posted May 8, 2009 Share Posted May 8, 2009 It looks like the leaves being that bright are contributing a large amount of green light bouncing off the front of the building too... Link to comment Share on other sites More sharing options...
