Hi,

This is my test scene of interior. 10 min each on GTX260 just to see the effect. On the left side of the first image I try to simulate windows with glass (simple glossy material and opacity) and on the right side no glass. Result:
on the left - no environment shadows (in the area of the ceiling and column)
on the right - there are shadows (in the area of the ceiling and curtains)

If I delete glass everything is fine.
What is wrong with my glass material? What is the easiest way to do the glass material that gives a good reflections and gives shadows and its fast to calculat?

Thanks!

to make a glass you use a specular material, set trasmision and reflect almost all the way up and ior 1.45.
Also I might be wrong but it seems like you are using directlight instead of pathtracing (which is the unbiased one and gives better results althou it'll take a little more time)
And btw, I might be sleepy yet, but I think you got your left and right mixed ;), like I said I was slept, I was just looking at the second image... lol

The chromatic aberration is way to heavy, it should be very subtle and barely visible.

Thanks Kubo but when I change material to Specular I can't find "Reflect" option. This is pathtacing but the openings are on 3 sides. BTW KUBO - my name is KUBA ;)

Thanks Chris. This is the first time I am using chromatic aberration and I will chang it in final version. I was too excited about new opportunities :)

the first channel in a specular material is "reflection" either set a floattexture with a high value or a rgb with almost white.
I thought it was directlight for the lack of shadows, but if there is light coming from 3 sides it could explain it. HDRI lighting gives a good mood to the scene, but it's hard to come with good shadows unless you use really high quality ones with really high ranges.

:lol:
Kubo is a misspelled name for "cube" in spanish, althou it really comes from a longer nick from way back when I used to play CS with my mates and we all had sesame street names and mine shared my real first name, so I just went for a description (trashcan).
Kuba sounds like a cool name, I like it.

Thor. I model curtain in 3D Max using "Cloth" modifier. There are a lot of tutorials in internet even in youtube. But actually the one I use in the scene is a free model so I can share it:
