Hello, I have a question about exterior rendering. My problem is a dark light inside the house.
I don't know is that normal or not?
I'm working on sketchup + vray from about 3 months, and I'm learning all the time new things. Before exterior render I've done some project with interior renders with good results I think 
What I've learned is that the exterior and interior renders need different light settings (camera, and so on)
So my question is: the lightening inside of the building can only be achieved by inserting there a source light like rectangle lights? - what I've done in this renders below.
Is there other option (maybe in vray sets) to light up some interior?
I'm using sketchup 2013 + vray 2.0
That's my main sets of vray:
Camera: Shutter speed 250 / ISO 100 / F-number 8,0
Environment: GI 1,0 (sun) / Background 1,0 (sun) / Reflection - HDRI file
DMC sampler: adaptive amount: 0,85 / Noise threshold: 0,008 / Min samples 12
Color mapping: Reinhard - Burn valee decreaed to 0,8
Inderict illumination (GI) - Turned on Ambient Oclussion -> amount 0,8 / subdivs 32 / radius 10
Irradiance map: min -4 / max -1
I think that's the most important vray sets
That's strange because I've wade through a massive number of tutorials about sketchup vray, about alone vray, etc and didn't find the answer about it
Some pictures of my test - low sets renders
1st - with a curtain and rect light in face of it to light it up because it was very dark
2nd - render with inserting rect light across inside the width of the house
3rd - render without any source of light in house.
Sorry for my english and regards
