Thanks Pilou, i found one very useful plugin in tuts you sent, and yes u are right, it is torsio chair from Bosnian wood furniture manufacturers Artisan http://www.artisan.ba/
They have great designs, all made from solid wood and hand crafted.
Yeah, you guys are right, about half file size goes to vegetation ( That big tree is 2.5 Mb ), and I am hiding it for every different view along with all unnecessary geometry, i even render from 2 different models with same scenes because together they would be huge. Ill try look into vray proxies, anything that can ease handling of models is a great help .
