Night Rendering - Lighting method & efficiency??

I'm starting to set up an existing project that we did as a daytime render and switch it over to a night time render. While inserting fake massing interiors and light sources behind all the glass I'm starting to wonder whats the most efficient.

 

It's actually turning out to be a fun Frankenstein stitch together.... a coworker did the exteriors originally on the building. So I deleted his lobby, and inserted the interior lobby model that I did. And then xref'd all that on top of the entry garden that I setup for rendering. I've attached a quick render so you can see what I'm working with. I'm working on realistically illuminating all the extra building windows now. Then I want to get some low level lighting on the walking paths through the entry garden....

 

I remember someone (may have have been chris nichols) mentioning the method of just placing objects throughout the scene with a vray light material assigned to it..... other option would be to place an array of vraySpheres throughout the scene... I know using the spheres would give me independent control over parameters such as subdivisions, but I'm also thinking that objects scattered throughout then joined as a single mesh object and turned into a light might be better for the scene. I really don't know I'm totatlly guessing here. Does anyone know which option would have more weight on the rendering in regards to time and efficiency in irradiance calculation.... or if one has has some factor that gives it a more realistic approach?

 

thanks - bk

just a hi-res still right now for marketing...... but I'm liking the way it's going and if I get a few seconds on a friday I may set it up quickly and toss it out to the renderfarm for fun.

 

why do you ask..... does that make a difference in using vraylights vs. object lighting?

Hope to see the finished work soon ..

been poking around on chaos's forums and got some good tips on exposure and setting a night scene. Basic comments were how using night film to get a proper night exposure the interiors will burn out and go alot warmer.. so here's the next iteration.

 

We pulled back the shot a bit so I have some more areas to light up.

 

c&c if i plz :D

The reason i asked if its a still or an animation is because you approach the lighting in entirely different ways. If doing a still, you just want it to look good and render times are fairly irrelevent (within reason). For an animation, especially with a deadline, render-time is paramout. Looks nice.
