Heres something I started to work on yesterday, and I dont even know
whats its gonna be... A gallery, office-space, café, something like that.
Anyway, I will work on it when time is given.
Idéas, C&C are welcome.

First Render - Concept
Second Render - Satin curtains
Third Render - Velvet curtains
I think it would be nice to have SSS in the curtains, but, Im new to that.
How should I start?
UPDATE 25/8
Fourth Render - First floor, Day
The curtains looks great here I think...
Fourth Render - First floor, Night
Fifth Render - Outside, Day
Fifth Render - Outside, Night
... but somehow, the curtains does not apear red here anymore. I have my theory that its because its only a one-sided mesh.

it's looking great, even at this early stage. It would be superb to see the light coming in through the velvet curtains but I'm no expert on SSS either. If someone could help you out the final result would look fantastic.

Indeed, you seem to got a very good start here for your scene

i like it so far.
About those curtains, perhaps try to keep the absorption low, to a .01 or around there, and the rest you figure out
Keep up the good work and update this piece

Looks like the beginnings of a space-station viewing lounge to me.

More hints, more hints. Just kidding...

No seriously, give me more hints.

I know That I need transmittance in my material, but how much do you think? And what about scattering? I dont even know what it is.

Could be, could be.

I dont know.

Im no expert on sss yet, but in the tutorial section herve put a lamp shade material that simulates sss, but is faster to clear the noise. That may be worth taking a look. I like the room so far.

...in addition to using sss, drapes seem to do well with very fine clip-maps...seems more realistic to me: the sss represents light coming through the individual fibers, but you need also to simulate the voids (air ~ Nd=1.00 in Maxwell) in the fabric for a really convincing result.

I have seen that Tutorial (seen but not tried it), and Im not sure if this is one of the cases where it should be used. But I could be wrong.

Hmm, I remember someone did a test on that a while ago (was it you?)... I will look for it later.

Was that the image 3dgeek did with the lounge chair and white curains?

Nice renders. Looks very promising.
If you are trying to do the shades as velvet I wouldn't give them transparency or sss; velvet is usually a quite opaque thick cloth. If velvet is not the goal then you can do what JD said: transparency or clipmap.
For the project (if you have something to do with the design): man, you have made a greenhouse; if sun hits there you'll have too much hot inside. I have just checked you are from Sweden; maybe it's ok there but here in Madrid you could die just by staying inside in summer. If you think you need to change that may I suggest a "ventilated facade"? That is a facade with two layers: the inside one closed as the one you have now and on the outside one that let's the air come through easily and receives the direct sun hit. This last one could be reflective or tinted glass. The chamber left inbetween gets as hot as in a greenhouse but, as it's ventilated, can easily take that hot out.

Im making a SSS vs transmittance-test right now. The difference is huge. I will post it here later on.

LOL. Thats funny. In the summer, your right, it will get really hot, even here in sweden. But, big fans and the possibility to open the windows, would be enough... I think.
But maybe I´ll place the building on the moon or something.
