I am trying to render this exterior view in the daylight with the interior lights on.  Even with the "sun and artificial" lighting scheme the interior is very dark.  I know there are enough lights because when I render a night view with the same lights the interior is very bright.  Also I am getting very long render times - a few days - even with a Windows 7 machine with 16 GB RAM.  Does anyone have any thoughts are tricks to get the interior to glow?

By the way, I have also tried Cloud Render and it changed most of my materials so I don't think that is an option.

Here are my render settings:

Best

Exterior: Sun and Artificial

Summer Solstice: 11am

Sky: No Clouds

No Haze

Exposure: 12.5, Highlights: .06, Mid Tones: .5, Shadows: .2, White Point: 6950, Saturation: 1.8

After rendering did you try to "play" with your "Adjust Exposure"?

Thanks for the tip; I didn't realize I could adjust those settings without rendering again.  The interior looks better at exposure 10, but the lights still look like they are very dim.  Perhaps I just need to crank up the wattage?  Also the exposure change makes the exterior sunlit portions too bright.  I guess I could save both exposures and combine them in photoshop.

You might try adding a bunch of studio lights just for the render,

make sure you group your lights, and turn off any that don't cast light to the exterior.

Cheers

Okay I am trying one with the Studio Lights; will post if I get good results.  I turned on the the daylight portals as well and that seems to help in my quick tests.  Why would I turn off the lights that are not casting to the exterior?  I want the interior to be lit up as well.  Also is there any advantage to grouping the lights other than being able to control them easily?  CryingDoes this help render time at all?)  It does not keep my light grouping when I close the view and reopen.

Thanks

Lasher,

Regarding the lighting groups, click on a light fixture, you will see a Modify|Lighting Fixtures Bar,

select the Light Group: Create a group and add the approiate fixures to that group, this way they will be saved.

Then in the Render Dialog, Lighting Sceme: select Interior: Sun and Artificial or Exterior: Sun and Artificial

then the Artificial Lights Button, and uncheck the lights that you don't need for the render. This will speed up the render times.
