Interior Daylight.

This is what I have after 150 passes on E0. I believe it could be better. Feel free to tweak materials and adjust light as the need be.

Finally got the drawing file upload. Looking forward to your contributions.

I always have an invisible omni-light to help with the shadows that is what you probably seeing.  

They are about 11 light sources, 9 you can see and 2 you cannot, daylight from behind the camera and the invisible omni-light. 

The coloured lights to help add dynamics to the space and to enhance the colour bleed.

It's the inner glow of the lamps I have to work at but now have no idea how to archive that.

With a bit of photoshop I have this.

That's nice picture Akin!

It's not a horrible picture-- but it is a terrible simulation.  The thread is entitled "Daylight Interior" but you've turned the sky off and no direct sun is entering the space-- so you're not simulating daylight at all.  This space will not look like your picture during the day.

For these, I did the following:

Turned the daylight settings on correctly-- I actually cut the default daylighting in half using Channels.

Fixed the units (was inches instead of mm when I loaded this into ACA 2013-- appears to be OK in yours)

Deleted the invisible omni light (a really bad idea.)

Changed the light colors back to white (a bad idea unless you want colored lights in the real space.)

Using e4 I get this:

Without daylighting:

There's still something wrong with the lights that I haven't figure out yet-- but they're pretty good.

Here's what I get with e4 when I turn reflective caustics on for the metal housing of the pendant lights.

I still think there's something wrong-- either with the construction of the light sources or with my stuff-- I can't explain the asymmetry on the ceiling and I don't have time to check right now.  Kind of cool, though-- I think this has possibilities.

thanks.

Will follow your advise since the clients wants more changes on the model. By the way like how many passes of e4 produced this?

I just stopped it after 166-- just over 6 minutes.  However, I did have the daylighting turned on even though I had the daylighting channel turned all the way down.  If I would have turned the sun/sky off this would have taken about 3 minutes on my machine-- perhaps 8 minutes on an average 4-core.  

The first rendering I sent, without reflective caustics, ran for about 13 minutes.

Here no coloured lights but bounces are at 2 and bleed down to half.
