Sun Light in Interior scene

[40th]

I have an interior scene where sun's light penetrates the the window and hits (directly) the wall and floor.
My question is what's the best* way to intensify that specific illuminated place?

By increasing:
Sun's size multiplier ?
Sky's multiplier ?
GI multiplier ?

For illumination of the interior scene i use 4 rectangular lights.

*Best result in Minimum render time

I think the Sun/Sky is meant to be set to 1.0 - so I'd adjust the exposure to the point where the sunlight is the way I want it. Then adjust the interior lights to fit.

And maybe , play a little with "corrections control" in the frame buffer, after the rendering it's done.

Re: Sun Light in Interior scene

Thanks for the suggestions.
I'm more of exterior guy, so i could use some tips here. I have 4 visible windows int the scene so i placed rec. light behind each window.
Do you have any tips so my final render won't be (time) endless ?

Teofas has shared his visopt, witch is well balanced, and, you will not have so much color bleeding. I mean, if you have white walls, you will get white walls. Another thing, the lights from the windows, has to be white. The sun will do enough, regarding worm colors and everything. It;s not a rule, but in this way I usually work.
Good luck and show us the result!

Can you direct me to his settings?
The lights are set to white color.
I enabled "store with iradiance map" for all 4 rect. lights. I read that it's speeds up the render time and doesn't deffect the quality.

Good luck and show us the result!

Thanks. Sure'll do

Can you increase the sun intensity in sketchup? If the rest of your scene is perfectly lit then I would just increase that if you can.

Thanks John.
I think i got it right.

Re: Sun Light in Interior scene

I'm gonna throw a curve ball atchall...I would certainly play with exposure, but this can blow out the area exactly where the sun comes in. There's another alternative that's cheep, easy, and you won't have to call it a cab in the morning. In the color mapping rollout, every color mapping mode has a Light Multiplier and a Dark multiplier (although in Reinhard its refered to as Burn and Multiplier, respectively). In Linear, along with exponential modes, both of these values should be set at one, but if we spend a little time to tweak these we can get the appearance of more light in our scene with out touching anything. I would start by increasing the Dark multiplier ever so slightly, doing tests, then seeing if it can handle a little more. You've got to be just a little careful with this as it can throw off your colors slightly and/or cause some interesting results where your shadow tones meet your mid tones. It is however a simple adjustment that's worth the 5-10 min to test, and if for some reason you don't like it...set it back to 1 and forget that it ever happened.

aaah! I've been looking for the Light and Dark multiplier. I never though it was dependant on the type of Colour mapping. doh!
