OT

okay, thanks

It seemed that the picture is noisy (for a high quality render)... maybe it's because of the resolution... 0.007 is very good.

thanks, did you mean to increase the noise ? I'm already using .007

1. try to find new material for the glass from the windows try http://www.vray-materials.de/ 2. use vray lights to project some natural light from the outside. Even better - use HDRI 3. there's not much reflectivity in your materials, they seem too "paperish". http://www.vray-materials.de/ 4. use bumm mapping. Especially on the carpet material. 5. change noise threshold to 0.02 (for the latest Vray) or 0.01 for older versions. Good luck!

3ds max it is

What software are you using?
