Hi guys,

I just tried to render the the night scene with Kray. I'm not sure what was wrong with my scene. Need some tips and help from you guys.

Anyway how to make more glow on the objects in Kray? Already put the higher amount but not much different.

You need some light from environment. Glow you can do in photoshop...

Ho ho You put level very high. Nights views are difficult All ideas are welkome, even creazy...Personaly I think light coming from rooms are to weak, so good idea is put lumi panels in windows positions to outside direction. Also many lamps outside (spot lights, IES fundament lights ) is good idea. I suggest watch Evermotion for that and get idea.

Jure - What do you meant by 'need some light from the environment'? Light from the Physical Sky or native LW? For the glow do in Photoshop? How about the animation?

Janusz Biela - Yes, it's very difficult compare using native LW radiosity. Ok, actually all the windows surface are luminosity. I made a random amount 75%-250% for luminosity and the glow about 50-100%. I still can't get it what do you meant by 'many lamps outside (spotlight, IES fundamental lights)? Can you share the link for Evermotion?

Thanks guys.

I suggest you first find a good reference photo of what you are trying to achieve. Your building is completely black so for start you need to add some light from environment so your facade gets some light. Best night renders or photos are taken just after the sunset when the sky still has some interesting colors. You have several options on how to light your scene: physical sky, light dome with texture, LW textured enviroment.... I think the best way is to find a nice spherical texture of a evening sky and map it to lumi sphere or LW textured enviroment. Then you add some lights outside that will make render more interesting. Search on web for tutorials and watch other renders for inspiration.

Errm. Windows' lights need to be more varied imho. I would use either a procedural of some kind (IFW nodal for instance) on the luminosity channel or, if you can, get Vroom - although it will raise rendertimes, the results are usually worth it. Also, the difference in luminosity between the windows and the street lamps is a trifle too high - those lamps don't seem to be doing anything at all, in fact. As for glow... Kray doesn't do glow - it's a post effect. But you can add it easily enough in PS or AE: just duplicate the layer, play with levels a bit until you get the appropriate contrast, apply a gaussian blur with the "right" size and then use "screen" for layer mode. Adjust transparency if needed... you should get something like in the attachment.

Thank you so much for the information Alexos.

Ok, I've the vRoom plug-in but seriously tell the truth that I'm 'not really like' the library from vRoom. I just starting make my own library for vRoom but need to hold for awhile because of this project. . Ok so about the lamp post that's meant should I put the light source on each lamp post to get the 'area light on the ground'?

Anyway thanks for the tips for the glow. Will try it later on.

Yeah, I've been thinking of building my own library as well but, you know... it is a rather time-consuming task, so yeah, it's on hold here too

As for the street lamps, their wattage is usually pretty high - take a photograph of a street at night and see how overexposed they look - so the fact that, in your picture, you only see a small white dot which doesn't light the road at all makes it look a bit strange. Depending on the shape of the actual thing I usually use an inverse-distanced point light or a spotlight, which will give you those romantic-looking pools of light... just my opinion of course!
