Hi there! First time writing in the Forum
Just found this thread and super interested in Arch Viz conferences as well!! I've never been to one and looking into what to choose for next year.
Regarding OneTwo's comment the event in Italy is called Immersive Architecture Conference ! http://www.im-arch.com/ and I've also found ADX The Architectural Visualization Event. Any others around Europe that are solely focused on ArchViz?
