Awesome, the block render is very realistic.

Hey pal, this is Indigo we're talking, did you really expect anything else?

Means a lot coming from you :) Thanks. It took about 2h to model and texture. I went a touch too far with the bump on the wood but didn't feel like re-rendering. I'm on a 2006 iMac so EVERYTHING takes a long time.

Oh and this is Sketchup with Skindigo.

I'm guessing from the noise that it was rendered with MLT, I strongly suggest you render simple exteriors like this with non-MLT, non-bidir PT. It'll be about 4-5x faster to converge, if not more :)

No MLT. This was either straight PT or bi-dir (can't remember) with super sampling factor of 3. If you're talking about the noise on the floor, that's a ISL shader for bump to make the surface less uniform.

i tested 5x5x2,65m box with walls,floor, 6x IES lights and one small window with environment color (pinkish)
quite impressive result for room lit by IES lights only, all IES are 35w and 3600k temperature.
aperture diffraciton : ON

Dcm: Nice test!
IES lights don't have the most efficient sampling right now, I'll have to work on improving that soon :)

ono : thanks.
would be great to have option to select shadow "shape". I prefer softer shadows from spotlights. As you can see, ies are generating quite sharp shadows tbh

i used AD because of nice light effect comming from spotlight`s reflector beams. Without AD, reflectors are empty because IES is not physically based light and its looking weird. I prefer using AD instead of placit emitters to reflector beams and doubling rendertimes having x2 emitters in scene.

Yeah, there is an issue with IES lights that there is no light coming out 'sideways', hence they sometimes appear black. I think a solution to this that I could implement is to always emit a little bit of light in all directions, in addition to the profile described in the IES file.

and something like "shadow smoothness" ? 1 - smooth shadows, 2-3-4-5 = very sharp shadows ?
possible ?

Do you mean shadow smoothness as cast from IES lights? If you want smoother shadows, you can always make the light source bigger.

but making bigger IES which is built in spotlight = big aperture diffraction effect, no?

Making the IES emitter bigger will change the A.D. effect a little, but will still look mostly the same.
