I made a very ease diffuse depth test on simple model. I tested time and quallity.

GI Settings:
600/300/15, Acc. 60%, color mapping: exp - on, m. darker 1.2, rendering to 32 bits

LIghts: rectangle area light in door with area shadow, sun with hard shadow and really simple sky (a white color only).

Render time 00:02:21

tnx pzdm,
really interesting tests.
did you used the same illumination settings for the material of the white room?
i think that most photometric software use different percentages for lighting reflection (usually 80%-50%-30%) on ceiling-walls-floor materials.
(lighting reflection can be translated into gi generate/recieve settings).

ps: what happens if you use just the sky to illuminate the scene?

Hi George
in "white" test is one material only - default grey - Brightness 80%. I wanted to achieve a nice and clear result on clear modela and surfaces, thus there are not different settings on cells, walls and floor.

About sky: I use a Sky for "supporting" GI only, it is not major object in this settings.

Bye Pavel...

PS: OT - where are you from? Becouse I am looking for nice and complex byzantine wall material - texture, I plan a scene as a tribute to heroic Constantine XI.

Hi there
I have tried a georgeīs trick as well

Walls 100% (generating GI), Green wall 75% and Floor 50%

hi Pavel, really nice work you have done here,
i am from greece -> complex byzantine wall material - texture is not a problem to me
(i can scan my architectural books, or take a walk downtown, thessaloniki is full of buildings of that period and take some snapshots)

ps: i did some similar tests here (http://forums.cgsociety.org/showthread.php?f=176&t=419804), trying to achive natural look lighting, with natural light sources, i.e sky obj for daylight scenes, and using *.lvk files for luminaires for nightshots

Thx for it! I bought few books for my project (The walls of Constantinople AD 324-1453, Men At Arms Byzantine Armies 1118 1461), I have Rancimanīs The Fall of Constantiople, a notice from one defender of this beutifull city Nicolo Barbaro and really many pictures from my visite. A broken and destroyed defense system at Lycos river, a place of heroic Constantine death in his last lost battle against agressors - it given me an idea for 3D scene. I donīt know if I have a skill for it, but if I find a time, I will try it. THX again.

I know your thread...
