A great stream was posted to YouTube which takes us into a city under development. We get to view the massive city gates and also get the view the process which was used to build them.. from the initial concept art, through various refinement stages to the final full render. I'm constantly amazed to see how this is done and how no small detail is missed. 'll probably spend months of time just looking at small little details when the game is released!
Also fascinating was getting a glimpse "under the kimono". Inside of the massive city of Thronefast, we can see many buildings as well as what are placeholders of sorts through a process called "grey boxing". This is where in-game structures are roughed in using flat grey surfaces. This really helps the world builders calculate and adjust the scale of the different structures in relation to the other in game items like buildings, walls, decorative objects, etc. Once again, watching the time and effort which the team is putting into budding this world is simply amazing.
