Hi there!

My current project needs some rendered images from the entrance of a bath
which is currently build.

In the attached image i marked the positions of my lights and some Problem areas.

The artefacts from the top-light-field are probably caused by the shadows of the
arealight directly beneath the light-ceiling.
My main question is how to achieve more realistig lightning (specialy under the tables).
It all has this "unnatural flat" looking.

Thanks in advance for your comments and help!

Have you tried an HDRI to light your scene? That along with radiosity might produce the desired effect.

Try adding a second set of lights along with your first lights with the falloff set higher and the brightness down to simulate more natural falloff. (a tip o the hat to MV) You might try appropriate negative lights to stop the flat look.

before you get into GI, radiosity nonsence, you don't have to use area lights, they're slow as hell.you could replace them with let say 5 (1+4 instance) soft shadows 256 or 512 map size but no more because this overhead is very soft and difuse, Trouble shoot your image, turn all lights off but one (or groupe) and ask yourself if it looks as it should, then move to another. cherrios!

Hi

I'm going to give your advices a try as soon as i can get back to it.

The GI-Results are surely great, but rendertimes are not quite reasonable.
(just have an AMD 3000+, 1Gig RAM) With a better (dual / quad Xeon) this could
become more handier...Or having a Maya-Renderblast-like functionality 8-)

With a small room and some windows I can achieve nearly GI-Quality Images with
just some pointlights (light-source, corresponding bounce-lights, fill-lights...).
For scenes like this i'm not quite sure where to begin and what to look for.

Would be great to get some more hints and tips regarding this....

Bye...
