Hi guys, this is the first test, I try to learn how to illuminate correctly a iterior scene…
C&C are welcome!

Re: Done’s interior
Jackson gave me about a thousand tips in this topic:

I can’t thank him enough
Edit: Oops… just realised this is a Rhino thread.
Re: Done’s interior
It’s still relevant, because it’s about vray. And since vfsu and vfr has the same V-Ray core those tips can fit for VfR also. 
Re: Done’s interior
thanks for the tips!
;D
Re: Done’s interior
Hi, i saw your settings and there’s a wrong things ;D
Your LC settings are incomplete, pre-filter and Glossy rays are important options. You should check it both For final renders you should decrease Sample size - 0.005 or 0.002
For IM - Samples are too big, this value may increase “flying” effect.
Value for Samples 20 or 30 are quite enough. For final renders you may increase HSph Subdivs to 80-100-120. For bring more detail you may increase Distance Threshold to 0.2-0.3-0.4. You should check - Sample vizibility.
Re: Done’s interior
Alexander, thank you very much, ill’try it, but i want to use the combination qmc and light cache…
You think, it’s a better combination of engine???
;D
Re: Done’s interior
No, DMC is too slow especially for complex scenes, like interiors. IM+LC is perfect. In some cases, you may try DMC like secondary engine. What’s your inconveniences about IM? It makes great job, when it’s set-up correctly
Re: Done’s interior
Hi
As Alexander said, the best combination for interior scene are IM for the primary engine and Light Cache for the secondary engine. For product design I use to use IM and DMC, usually the product render is a close up shot and you need to get all of the product detail and DMC is the most accurately solution.
Re: Done’s interior
wonderfull, now it’s all my hand, next week ill’post the results of the suggestion of alexander about done’s interior, with the correct setting.
The last question is:
I need to put a rectangular light nearest of the window for simulate the diffusion of the light, or vray sun it’s enough???
???
davidooone.
Re: Done’s interior
Use the Rectangular Light (Alexander Tip too)
;D
Re: Done’s interior
Yes, Rec light on the window(s) with big intensity (as an example - above 100). You should check - invisible, and store with IR
Re: Done’s interior
Hi David.
Looks a lot better, but try to use a blueish color for the rectangular light in order to simulate the natural light color of the sky.
Re: Done’s interior
hi, i0ve stetted the IM & LC how Alexander say, but something goes wrong, the reflection on the wall near the window… the settings of the light isn’t correct???
rec light
Is necessary modify the sampling value of the rec light???
Ferdinando thanks for the tip, ill’change it…
;D
Re: Done’s interior
Fernando, i’m sorry ;D
Re: Done’s interior
I thing that there’s no correlation between IM+LC settings and these artefacts. These settings are only for FINAL renders, for tests you should decrease them. The reasons for these artefacts may be complex. What is your Color mapping setting? Did you use Clamp output and Subpixel? What is position of the sun - it’s too dark outside? What is your image sampling settings?
Re: Done’s interior
Your setting are pretty high, so your scene should be splotchiness free. Where you have place the rectangular light? Try to place the rectangular lights inside the room, in front of the windows.
Re: Done’s interior
i’ve putted it nearest behind the windows… now i move…
thanks.
