stayinwonderland Posted August 2, 2012 Share Posted August 2, 2012 I've been struggling with an exterior scene which has dusk lighting so interior lighting will also be present. To get the interior lights to light up the rooms and look full and warm, I have to increase the power of those lights tremendously. I've just been playing with IES lights and had to ramp up the power so much I think it caused 3dsmax to crash repeatedly. And even then it still wasn't bright. Perhaps in such a scene I need to make the camera expose more but turn down the sun and HDR dome? What's the usual general procedure? Link to comment Share on other sites More sharing options...
Stephen Thomas Posted August 2, 2012 Share Posted August 2, 2012 If you have a mix of different interior lights it would make sense to expose the camera for your interior lights at their default intensity values, then introduce your dome light/sun and adjust them accordingly. There's no need to stick rigidly to having the sun at 1.0. Link to comment Share on other sites More sharing options...
stayinwonderland Posted August 2, 2012 Author Share Posted August 2, 2012 Yeah, I've just lowered the hell out of all my environment lighting and brought up the camera exposure. I think it's working better. Will see after a few renders. Thanks. Link to comment Share on other sites More sharing options...
Stephen Thomas Posted August 2, 2012 Share Posted August 2, 2012 I'd also tend to use a target direct light for dusk shots rather than a vray sun. More control over lighting colour, and sun can get a bit buggy when close to the horizon. Link to comment Share on other sites More sharing options...
Ismael Posted August 2, 2012 Share Posted August 2, 2012 A couple ideas although "expose the camera for your interior lights at their default intensity values" is invaluable advice. http://3dxmodels.com/index.php?option=com_content&view=article&id=29:exterior-scene-night-lighting&catid=9:tutorials&Itemid=10 http://cgworkshop.org/showtut/35 Link to comment Share on other sites More sharing options...
Umesh Raut Posted August 5, 2012 Share Posted August 5, 2012 One more humble suggestion. Wouldn't rendering and compositing different layers give better control in post? Link to comment Share on other sites More sharing options...
stayinwonderland Posted August 5, 2012 Author Share Posted August 5, 2012 Thanks for the links Ismael, I'd seen the second link but not the first one. And Umesh. I might do that. I just find I have to compete with edge contrast and if I have trees hitting the environment then I have to clip those out totally seemlessly, which I'd rather not have to do. I had noticed that, overall, I wanted more night than dusk. Or a later dusk. So I dropped the environment light right down and upped the exposure and also upped the burn value - something I never ever do but seems to work. Here's what I have so far...

Ismael Posted August 5, 2012 Share Posted August 5, 2012 Love the visual ques of the lawn lamps. They add a lot to setting the time and the overall mood. As a personal preference I would punch the contrast a bit up. I feedled with your latest so don't ask as I do not remember what I did but this look ok to me from afar... http://imageshack.us/photo/my-images/225/015015.jpg/ Link to comment Share on other sites More sharing options...
stayinwonderland Posted August 5, 2012 Author Share Posted August 5, 2012 Cheers I'm a ways off finishing it yet, this is still a WIP shot. But don't worry, I'll probably photoshop the hell out of it when it is done! Link to comment Share on other sites More sharing options...

I know of course that you are not done, judging by the caliber of your past work. Looking forward to your finishing touches, cheers. Link to comment Share on other sites More sharing options...
Umesh Raut Posted August 6, 2012 Share Posted August 6, 2012 Ismael : The imageshack image I see is way too dark, due to increased contrast and sharp, too. In real world case (especially with human eye+brain adjustments for exposure and sharpness) it usually would give out much more detail as in light information and filter out the sharpness of the grass blades nearer to view-point. We tend to focus only on a smaller part of the whole world (picture) around us at any given time, hence that illusion of blur. Its only a humble honest opinion, though.

etche Posted August 7, 2012 Share Posted August 7, 2012 (edited) May I ask how did you achieve that grass? Is it with a grass plugin? vrayfur? vray proxy? Thanks! p.s. loving the image so far Edited August 7, 2012 by etche Link to comment Share on other sites More sharing options...
braddewald Posted August 8, 2012 Share Posted August 8, 2012 I wouldn't worry about it too much now, and just take care of it in post afterwards. I'd also like to ask about the grass -- is it vrayfur or is it scattered geometry? Link to comment Share on other sites More sharing options...
