and another try..optimized.FInally got a clean result using very few samples..still there are artefacts but can be eliminated by increasing the fg samples a bit.

same light set up as before

gi
photons = 500 radius 2.2m
samples = 100 radius 2.2 m

max trace depth = 10,10,sum = 10
fg = 500 max = 1.0
min = .1m
max trace depth = 15,15, sum = 15

global light settings
same as before except decay = 1.4

second image was rendered using the same settings except the fg samples was raised to 700 and decay to 1.6.
render time with all computations took 18mins:46 seconds on a 3.0ghz
P4 with HT laptop with 512 ram

another optimized render.lowered the settings the number of samples and compensated with little adjusments in fg.


settings:
gi
500 at 2.75m radius
samples 100 at 2.75 samples
max trace depth 10,10,10

fg 300 max = 10
min = .1
max trace depth 20,20,20

global light settings
energy = 1600000
decay = 1.6
photons 1,000,000

render time 9mins:58secs

here's my go at it
rendertimes : 9 mins 16 sec for the first, 36 m 26 s for 2nd image
(only diff is the final gather : 100 and 3000 for scnd)
this is just to get rid of the splotches in the deep cieling areas
rest is completly similar

10000 gi photons 75cm radius
energy 50000 decay 1.9
fgather 100 in first - 3000 in scnd (no min or max)
no log exp control

glass in windows is hidden
did some finetuning on the materials (nothing big)

used 2 mr area omnis infront of each window
and 1 mr area spot for sun

edit : added gray versions
same deal : fg 100 and 3000 rndr times 6m49 and 27m03

max file in attachment
try to make your own setup first pls and post that one on this thread

and then mabey have a look at mine to get out some settings or change your own setup
there's no point in doing exactly the same scene over and over again...

cheers

Hopefully "alternative" lighting solutions will be accepted for this latest test. Here's my setup:

1 Mental Ray spotlight for the sun.
Energy = 90000
Decay = 1.5
GI = 500 photons with a radius of 50.0
No Final Gather.

I then used the materials that were pre-applied and simply added a photon shader and set the photon shader to transparant. I did this to allow all the photons to enter the room for my ambient light pass. In hindsight, I should've used more decay so the room would be brighter where the sun enters the room. As it stands now, it's too evenly lit....but it's late and already rendered so I'll continue.

Once I rendered the ambient light pass (1 minute 28 seconds), I used the material override to globally use the dirtmap shader for the shadow pass, which rendered in 2 minutes and 10 seconds.

So, with a total render time of 3 minutes and 38 seconds here's the images. A little photoshop tweaking on the contrast would probably help the final composite.

<i'd rather call it a very innovative lighting solution. very good to have somebody "unhaul the box"
<most useful for evening shots u think? i feel the source of light to be from the center of the volume(maybe because of the ambient source). not for scenes with light coming from window. hope to see soon ur render with decay.
<pardon for asking...from where did u do "final compositing"?

In photoshop, I started with the ambient light pass as the background then added the dirtmap pass in a new layer and set the new layer's mode to multiply.

Yeah, I think it would work better for night renders, but I will give it another try tomorrow...I have an idea but I need to sleep on it first..

<here's my shot @ it.

<GI:1000 photon accuracy radius 0.8
<FG:fg 3000, radi 2,0.2
<global: photon count 300k,energy 100k,decay1.6
<with log exp control

hey jeff,
you can do similar stuff with my endresult (i mean the dirt mix in photopaint-photoshop)
you do not need to use the ambient 'washed out' ground layer you made
(if you do not mind the speed diff. that is)
that way you will have more 'dirt' in the corners of the walls and all, but still have a lightning feel coming from outside...
i'll give it a try if i have some time later on...

great thinking about the transparent photon shader !!!
this might be the solution to make reflective glass in windows but that still lets the photons go inside !!! instead of just hiding the glass.
mabey the use of caustic photons might not be needed anymore for glass tables inside the room to get transparent shadows with this 'transparent photon shader'...???

i'll give it a try later on as well.
