I recently saw a thread about lighting on CGTalk, where they were competing to light a bedroom scene. So I thought I'd have a go at it. I'm not using the same scene they used, because it'd probably melt my computer, but it's close enough.
This isn't finished yet, I still need to add some stuff and change a few thing. So I'll be updating this thread as I progress. That is, if I don't get side-tracked and stop working on it. And if anyone wants to try lighting it better, I'm providing the .3ds file below.
Rendered using Blender 2.49b Internal Render Engine. Render time: 4 minutes 55 seconds.

Added a few lamps and a little table.

Is there only 1 light source in that scene or do you have a few omnidirectional lights in there too?
-
Very nice. I'm a sucker for brilliant lighting :)
-
I like the lighting from the window. If you want some awesome lighting, id make the lamp shades semi transparent and put low power light sources there. The shadows will look very nice.
I also suggest you try and not have pure white light sources, since in real life there arn't really any pure white light sources.

There is one spot light and one hemi lamp. The hemi provides some ambient light, not much though, and I probably don't need it.

Yeah, I was going to do something like that. But the more stuff I turn on, the longer it takes to render. The last scene I rendered took 44 minutes to render, just because I enabled AO on a surface. :-\

I stole Crunk's floor texture he used for his bullet and applied it to my floor. :)
Render time: 22 minutes 17 seconds.

Get the poly's going and add a quilted sheet :)

That's not as easy as you make it sound, but it's coming. I need to make a new bed first, that one is kinda just a place holder. :)
-
I figured out I could use Blender's Cloth Simulator to put a sheet on the bed easily. And yes, I realize there's a copy of the bed outside the window. ;)
Render time: 24 minutes 41 seconds.

Looks cool :thumbsup:

Well, I was talking to Spanky and we both agreed there should be a picture frame in the room, even though neither of us have one in ours. I also made a cube-like clock radio in like 1 second, it's pretty cool.
Render time: 25 minutes 24 seconds.

lol my suggestion: picture frame above the bed. either abstract art or a landscape painting.

woo all of this are crazy :P Nice nice!

I'll do something like that when I take the time to texture the scene.

That might actually be funny, but I'll just let you photoshop that in. ;)

Thanks!
Alright, I haven't had a lot of free time the last few days, but today I managed to get a little work done. Basically I just added a modern-looking shelve above the bed, with a few books and a picture frame. And I spent, probably, 20 minutes detailing the mini blinds, which you probably can't even see. I also added a window, which is kinda causing some shading problems.
Render time: 15 minutes 50 seconds.

Small update, I tried fixing the shading problem with the window, I think, it's a little better. And I added a pillow, it's a little weird still.
Render time: 19 minutes 41 seconds.

Alright, I'm trying out a new render engine called Yafaray. Yafaray has photon map based rendering, which simulates lighting much better than the method Blender was using. After playing with it all day, I think, I kinda got a result that looks alright. It still has a few problems, but I think I like it better than the Blender renders.
Render time: 25 minutes 32 seconds. Rendered using 2,500,000 photons, with 128 FG samples.

By the looks of that image, you have a light source on the ceiling?

Yeah, I couldn't get enough light in through the window to light the scene well. I guess because of the way the rendering works, not enough of the photons make it through the shades to light the room. The result kinda looked like when you take a picture without enough light, and there's a lot of noise on the image. So to make things look a little nicer I added an area light in the middle of the room, which kinda shows on the floor more than I wanted. I probably should position it more over towards the window or something.
Overall I still like the result better, and I think if I can get it right, it'll look pretty nice.

Yafray does physically correct lighting calculations on all surfaces from shadowing to light diffusion and diffraction (both seen on the wall where the bookcase is located). Nice pillow.

Yeah, like if I slap a green cube in the scene for no reason, I'll get a result kinda like this:

Nice pillow.
Thanks. :)
-
The noise is ... =\ not something you'd think about seeing. Im sure theres an option in there for photofiltering or something that adds noise at low light. Meh, Google.
Nice cube, looks edible.

I rendered that at lower quality so it wouldn't take as long. There's an option that will smooth the noise out, called "final gather". Basically you should use as many final gather samples as possible, which is like 4096, but I only used 32. in the image before the last I used 128. So you can see why it has more noise. Also you should use as many photons as possible, but I run out of memory anywhere above 5 million.

Cool cool. We should be sponsored for this stuff honestly. Theres no reason someone shouldnt give us kickass computers to work with :P

Go for it (http://support.dell.com/support/topics/global.aspx/support/dellcare/en/by_phone_DHS).

Everyone call 1-800-283-2210 and tell Dell that mAAp Pack is requesting sponsorship to improve and refine the research and development of technological video interactive entertainment for use with multi-dimensional modeling/scaling, aural synthesis, virtual construction, and dimensional collision detection.
P.S send cookies along with the computers.

Not to mention for fun too :)

Alright, I haven't done anything with the room today. But yesterday I moved the lights over by the window to make it look more like the window was the light source in the room. Hopefully that worked. I left it rendering when I went to bed, which didn't take as long as I thought.
Render time: 39 minutes 43 seconds. Rendered using 2,000,000 photons, with 256 FG samples.

Oh yeah, a 16 core server with 32 GB of memory would be real nice, running Linux of course. :P

Just ruined it.
Anyway, the lighting still looks weird/wrong since you wouldn't have lights turned on in a room that lit by outside light.

How did I ruin it?

Right, but I can't get enough light in through the window to light the scene. The spot light outside, that is acting like the sun, is already several times brighter than what you'd normally need. So I added lights around the window to kinda make it look like light is bouncing in around the shades. I don't know, maybe I can make the surfaces bounce light better, worth a look I guess.
-
I know UnrealEd is far far different than Blender but isn't there some Ambient Light setting? In UnrealEd, you don't need light sources to light a room, you can use Ambient Light. Just a thought.
-
There is an option to make a surface actually emit light. Which might actually help, I'm trying it out now; I'll post back when I have a render. :)
EDIT:
Alright, the only light lighting this scene is the spotlight outside. I kinda think it looks washed out, but it will probably improve with textures on everything.

Its trying to be realistic by washing out the light in the window since IRL in a dark room you cant see thru a light source that bright.
-
How is this going along?
-
I'm still working on it. I just haven't had as much free time lately.
-
Did you let this die off?
-
I haven't worked on it in a while, mainly because I have to texture everything and I hate doing that. But the last thing I did do was texture the dresser, which I think turned out alright. :)

I'm really loving the lighting.
Needs easy recognizable poster on a wall somewhere... requires minimal effort (just a plane or thin rectangle?) but could add alot visually.
I was thinking one of those over-used really common dorm posters would be funniest... http://www.collegehappenings.com/college/28-most-cliche-dorm-room-posters/

I'll be sure to do that next time I work on it, guys. I'm working on another project right now and really don't have time for this one.
