Hey guys,

This is my second tried for night scene. I really need help to fix this. Anyway where the noise come from?

Thanks.

I think a lot has been already answered here: http://www.kraytracing.com/joomla/forum ... pic#p13583

Thanks and yes Jure. But it does work although I follow all the steps, it's still unsuccessful, i keep wondering why? Need some advise.
I saw from Evermotion website, in Vray they has on light source for example like Vray Light etc. Should I use native background image?
I'm not really sure if Physical Sky doesn't work for night scene.

Ok here is 1 of the example perspective what I really want to do.

Well if you check your example then you can see that the image is very bright. Your image is totally black because your sky is black. Don't use physky, it's not meant to work well for night/evening shots. Find a nice evening sky texture and use it as a Textured enviroment or map it to hemisphere that will act as skydome. Check here for some nice evening sky images http://www.cgtextures.com/textures.php?t=browse&q=26543

Thanks for the link Jure. Now I understand a little.

Anyway here is 1 of the test render for the same project but some part on this image too darker. I already increased the lighting, physical sky, power etc but still darker. Any idea?

Thanks.

I think your tonemaping is too strong. What QLWF and Tonemap blending values are you using?

I used same setting for both QLWF & Tonemap. Should I adjust that setting for this part of the darker area?

Show the screenshot of your settings.

Here is the setting.

Looking at your render it looks that the contrast between areas in shadows and areas lit by sun is realistic. This is how it would look in real life too. If you want to cheat you can use more gamma or add it in post process.

What may not be perfect though is your materials. Check for your surfaces and increase diffuse parameter so more light will bounce off surfaces.

Hi Azmen,

the problem with the "nightly" images you generally see on magazines and websites is... they're not nightly at all! Take the one you linked for instance - that's early evening, at best. And there's a ton of coloured light sources around, too - what makes people think "oh yeah, that's dark" is the artificial lighting, something you don't usually see in renders. I'm attaching a couple of images as a comparision: this is a render I quickly put together (so please ignore the lighting artefacts):

and this

is an actual photograph of the same buildings, at night: if you notice, it looks pretty much like your first render, black black black! So your image was, in a sense, very photorealistic

Thanks Jure. I will double check the diffuse on the surface.

Also thanks ADP for the tips. Yes, I finally find out how to do that. But how about the glow inside the building? As I know Kray doesn't support glow in LW right? So everything about the glow, shiny, lens flare will do in PS? If there have something special plug-in for PS, what and where can I find it?

OK guys, this is the latest night view. If you see at the bottom building (podium/car park level) was not too brighter (less luminosity).
I already put about 2000% on that area even for the street lamp. Also at the podium/car park area, the surface something have a noise.
