Other wood textures and the ones which contain dirt or scratches that reflect less, were made with similar procedures, where all of them use specular maps, but not the reflection glossiness maps, because it didn't seem necessary to use them in every case.
The curtains material was made with the help of the opacity map. I wanted some patterns to be less transparent, so I made a b/w map where the cherries pattern is almost white, which means that it has almost no transparency (black means 100 % transparent), and the other part of the cloth is medium gray.

Since everything else was more or less dirty or stained, I decided to make the glass on the windows in a similar way. I drew some quick dirt maps in a brown greenish color in Photoshop with a few different brushes for the diffuse map. Then I just converted them to grayscale, adjusted the contrast a little bit and they were ready to use as the refraction maps and specular also.

There is also some Vray displacement used in the process of making the image, you can see it on the ceiling lamp and the green vase on the window shelf. These displacement maps are just images with small white patterns on a black background.

2 Lighting & Rendering
For the lighting I used 7 Vray planar lights, one placed at each window. You can see the settings on the image below. That took care of the scattered, indirect light.

For the direct light that simulates the sun, I used another Vray light, but this time set to spherical instead of planar. Since I wanted to create a warm morning atmosphere, I set its color to a bright yellow/orange.
