living room - light tests

hstokholm · Post by **hstokholm** » Fri Aug 17, 2007 4:38 am

Hey all..

I haven't used indigo for a while but I finally found some free time to play with it again

I have been recreating a living room in blender, and I thought I would use it to test different lightning..

But I have a few questions.. Is there a way to make the room more bright without it getting all burned out at the window..? And how do I make the lampshade more realistic in the night version..? Right now it is a blend between white diffuse and white diffuse transmitter..

Any help is apreciated

Regarding the window burnout, you need to use Reinhard tonemapping with lots of range compression. Try messing around in Violet; you will probably need to crank the pre-scale right up.

You're on the right track with the lampshade material. Try using less diffuse transmitter, and more diffuse.

p.s.: a couple more things: You need to bevel your edges, and this room is perfect for exit portals

Your bulb is probably too strong, and you should pick an off-white colour for the shade. The darker the colour the more you will see the lampshade with the bulb glowing inside.
Also, I would normally use very different light intensities for the emitters that actually light the scene and for those that are visible but mainly there for "artistic" effect. My neons, lightbulbs, etc, have very low efficacy/power. Just enough for them to appear lit. Remember this is pretty much like taking a photo. If you were to shoot an interior like this one, you would flush your scene with very strong softboxes positioned outside the frame. What you're getting here - the washed-out lampshade - if what you would get with an automatic-exposure camera - which is what Reinhard is - and only that light source in the scene. so make your hidden lights left and right of the frame a lot more powerful than the bulb.

That was fast

I will try to mess around with the tonemapping in violet.. Haven't really used that yet, but probably time for me to learn to use it.. And I will try out your suggestion with the lampshade..

I actually use a exitportal in the window.. It really speeded things up:)

You can download violet from the the download menu / Violet tone mapper above.

Good that exit portals are helping

One more thing, at least for the final render, make sure your supersample_factor is at least 2 (possibly 3 if u can afford the RAM).

BbB:

Didn't see your post before.. Some very good tips from you.. Will try it out this evening

Ono:

I will raise the supersample factor for the final render but I kinda needed my ram for other things during these test renders.. But now i'm of to blender

No problem. Would be cool to see the results. It's a nice scene.

Very nice pics

Is that a blender screeny, there in the first pic?

Thanks guys.. And yes Kram it's a blender screenie.. Needed a widescreen pic and didn't had patience to find anything else.. But now it's a image from a muse concert

I tried some of the suggestions, and I really like how it turned out.. Still a long way to go with this image, but it moving the right direction..

Edit:

Just some cleaner renders...

yes, that lamp shade is much better, now

Just a small update...

if anything seems off to you please don't hold back

Kram1032 · Post by **Kram1032** » Mon Aug 20, 2007 9:00 am

I see...
you moved the lamp, added some glasses, moved the pic and added some boards, where it was. On the boards, you also put some glasses...

Very nice

Any changes I missed?

New pillows.
I also just saw that your pic is a render. You can't see it if you don't know the picture.

yep you missed a few Kram

Sry if my update was to small for you but I figured I couldn't hurt anybody by posting it..

Just fooling around and trying some new stuff.. sry for the grainy render..

Sry, if my post appeared to tell you that... I actually simply played "spot the difference"

- it wasn't a too small update, else, I wouldn't have seen ANY difference
